Background of the Invention

FIELD OF THE INVENTION

This invention relates generally to systems for generating power and systems for producing gas products, and more particularly, to a system and method of employing exhaust and waste CO ₂ to enhance the growth of algae as a commercial product and as a feedstock.

DESCRIPTION OF THE RELATED ART

Prior to the 1980's it was normal and considered good practice to design, build, and operate dedicated manufacturing plants for most every product that was produced on a large scale in the world. Shortly after that period many industries became enlightened to the merit of flexible machining, and flexible manufacturing. Much of this paradigm shift was accomplished on the back of the modern microprocessors. This device allowed more enlightened design, and more importantly complex control, and precise control of involved processes. Many new inventions were required in the wake of this manufacturing revolution. Instead of an assembly line in the past making only one dedicated product, current best in class assembly lines make up hundreds of different products and models, in batch sizes of one, with no perceived loss of productivity or additional set up time. This clever thought process, and design, has netted many benefits to industries like the automotive world, heavy duty engines, and other hard goods manufacturers.

The energy world has not yet embraced this concept. There is a need to produce energy products in a more efficient and cleaner process than any carbon based process presently in use. One implementation of this concept does not use fossil fuels. In another implementation, the use of fossil fuels (such as coal) is minimized where possible. This is essential in developed countries, such as the United States, that have an elevated need for a "clean coal" electricity generation system, and for the manufacture of other fossil fuel energy dependent products, such as plastics, gaseous fuels, and fertilizers. In the United States and other developed countries, there is an ongoing effort to reduce the dependence on imported oil. It is, therefore, an object of this invention to achieve these goals in an environmentally friendly way.

Current power generation plants have only one primary process; i.e., to produce electricity by burning fuel and consequently emitting pollutants, such as green house gasses. One of the significant disadvantages of conventional power plants is that when they are brought off-line, and then restarted, they are unacceptably inefficient and produce exceeding amounts of harmful emissions. Modern power plants do not efficiently enable the throttling back of production of electrical power, and therefore they are operated continuously near the designed load limit. Since electrical power cannot be stored, power plants are frequently shut down and restarted in response to the varying demand for electrical power by consumers on a day- to-day basis, and as a result of differences in demand between day and night conditions. With few exceptions (e.g., hydroelectric, wind, and nuclear power generation systems) power plants burn huge amounts of fossil fuel at relatively low efficiencies. The average efficiency of coal power plants in the United States is approximately 34%. Natural gas plants are slightly more efficient.

The predominant green house gas produced by power plants is CO ₂ . In the present state of the art, coal plants in the United States produce on average approximately 2.01 Lbs of CO ₂ per KWH of power. Natural gas and petroleum plants produce about 1.6 Lbs Of CO ₂ per KWH. These are "carbon positive" green house gasses, in that they were removed from the ground and released to the atmosphere. In a carbon neutral process no new emissions are released into the atmosphere. In other words, nothing that has been removed from the ground is released into the atmosphere. Only existing carbon and green house gasses that are already in circulation are processed and released.

In a carbon negative process green house gasses are removed on a net basis from the atmosphere into a captured state. An example would be to extract CO ₂ from the atmosphere and capture it into a hard substance, such as a plastic. A better product would be fertilizer since it could then be used to grow plants and food that continue to capture CO ₂ .

It is, therefore, an object of this invention to provide a power generation system that reclaims heat energy that otherwise would be exhausted into the atmosphere.

It is another object of this invention to provide a power generation system that operates at higher efficiency than conventional power generation systems. It is also an object of this invention to provide a power generation system that eliminates the need for load cycling in response to consumer demand for power.

It is yet another object of this invention to provide a power generation system that greatly reduces emissions of CO ₂ . In addition to the foregoing, the current method of producing ammonia typically begins with fossil fuels such as coal, oil, natural gas, propane, butane, naphtha, etc. that are processed to liberate hydrogen. This known approach disadvantageously strains limited resources. The known processes liberate significant amounts of carbon dioxide and other green house gasses that are believed by some to contribute to global warming. In addition to environmental effects, the known processes have resulted in political unrest, such as in China where the population battled over the rationing of fertilizer containing ammonia. The political unrest resulted from the fact that the fossil fuels needed to produce the ammonia were preferentially redirected to other fuel starved areas. In 2006 the worldwide production of ammonia was approximately

146.5 million tons. It is believed that political problems will worsen in the future. For example, it was estimated that in 2003 83% of all ammonia produced was used to produce fertilizer. Moreover, it has been published that over 33% of the worlds food supply is generated through the use of fertilizer, and some have argued that the percentage is higher. It is therefore evident that with reasonably population growth and increasing competition for arid land, the reliance on fertilizer will only increase.

In 2004 China was the largest producer of fertilizer for the world at 28.4%, followed by India at 8.6%, Russia at 8.4%, and the United States at 8.2%. None of the operations in these countries use large scale renewable resources. Europe, up until the end of WWII, used a 60 MW hydroelectric power plant at Vermork, Norway to produce ammonia. The plant produced the required key ingredient, hydrogen, using an electrolysis process. Electrolysis is generally not economically feasible for producers who are not blessed with hydroelectric power. At that time, much of the ammonia was used to produce munitions for the war, and the economics of such application of resources was not questioned. The foregoing notwithstanding, the Vermork site was a prominent example of ammonia production using a non- carbon-liberating base of production to date. Plasma melters are now becoming a reliable technology that is used to destroy waste. At this time there are few operational plasma melter installations but the technology is gaining acceptance. It is a characteristic of plasma melters that they produce a low BTU syngas consisting of several different elements. If the plasma melters are operated in a pyrolysis mode of operation, they will generate large amounts of hydrogen and carbon monoxide. The syngas byproduct typically is used to run stationary power generators, and the resulting electric power is sold to the power grid.

It is, therefore, an object of this invention to provide a system for liberating hydrogen.

It is another object of this invention to provide a system for liberating hydrogen on a large scale and that does not require large electrical generation resources.

It is also an object of this invention to provide a system for liberating hydrogen that does not require consumption of natural resources.

It is a further object of this invention to provide a method and system of producing ammonia inexpensively.

It is additionally an object of this invention to provide an inexpensive method of using hydrogen to produce ammonia.

It is yet a further object of this invention to provide an inexpensive method of using a plasma melter to generate large amounts of hydrogen. It is also another object of this invention to provide a method of generating hydrogen wherein waste carbon dioxide is obtained from a renewable energy source and therefore does not constitute an addition to the green house gas carbon base.

Detailed Description

5 Fig. 1 is a simplified schematic representation of an embodiment of the invention wherein ammonia product is produced along with algae for use as a fuel. As shown in this figure, an ammonia producing system 100 receives municipal waste, or specifically grown biomass 110 that is deposited into a plasma melter 112. In the practice of some embodiments of the invention,o the process is operated in a pyrolysis mode (i.e., lacking oxygen). Steam 115 is delivered to plasma melter 112 to facilitate production of hydrogen and plasma. Also, electrical power 116 is delivered to plasma melter 112. A hydrogen rich syngas 118 is produced at an output (not specifically designated) of plasma melter 112, as is a slag 114 that is subsequently5 removed.

In some applications of the invention, slag 114 is sold as building materials, and may take the form of mineral wool, reclaimed metals, and silicates, such as building materials. In some embodiments of the invention, the BTU content, plasma production, and slag production can also be o "sweetened" by the addition of small amounts of coke or other additives (not shown), which in some embodiments of the invention includes fossil fuels. In other embodiments, the fossil fuels are combined to form a fossil fuel cocktail that includes, for example, a biomass material, municipal solid, waste and coal. In still other embodiments, the fossil fuels may be of a low quality,5 such as brown coal, tar sand, and shale oil.

The syngas is cooled, cleaned, and separated in a pretreatment step 120. The carbon monoxide is processed out of the cleaned syngas at the output of a Water Gas Shift reaction 122. The waste carbon dioxide 126 that is later stripped out is not considered an addition to the green house gas 0 carbon base. This is due to the fact it is obtained in its entirety from a reclaimed and renewable source energy. In this embodiment of the invention, the energy source is predominantly municipal waste 110.

In some embodiments, the carbon dioxide is recycled into the plasma melter 112 and reprocessed into carbon monoxide and hydrogen, or carbon and O ₂ . A Pressure Swing Adsorption (PSA) process, molecular sieve, aqueous ethanolamine solutions, or other processes are used in process step 124 to separate out carbon dioxide 126. Hydrogen from process step 124 is delivered to a conventional Haber Bosch process 128, which is a well- known large scale high pressure process for producing ammonia, or other similar process, to produce ammonia 134. The required nitrogen is extracted from air 132 through a PSA 130 or any other conventional method. As previously noted, the hydrogen is, in some embodiments of the invention, extracted from the plasma melter. Pretreatment step 120 and Water Gas Shift reaction 122 generate heat that in some embodiments of the invention is used to supply steam to the plasma melter, or to a turbine generator (not shown), or any other process (not shown) that utilizes heat.

In accordance with a highly advantageous embodiment of the invention, the waste CO ₂ 126 that is issued at process step 124 is delivered to a bioreactor 140 that produces algae at an output 142. The algae is produced using the waste CO ₂ and is delivered as biomass 110 to plasma melter 112. In addition to the foregoing, bioreactor 140 generates O ₂ at an output 144.

Fig. 2 is a simplified schematic representation of an embodiment of the invention wherein ethylene product is produced along with algae that is used as a fuel. Elements of structure that have previously been discussed are similarly designated.

In this specific illustrative embodiment of the invention, a portion of the CO and hydrogen obtained from pretreatment step 120 is diverted by a flow control valve 150 and supplied to a Fischer Tropsch Catalyst process 155. In some embodiments of the invention, the Fischer Tropsch Catalyst process is an iron-based Fischer Tropsch Catalyst process. This diverted flow is applied to achieve an appropriate molar ratio of CO and hydrogen, and thereby optimize the production of ethylene 157 or other carbon-based products.

Pretreatment step 120, Water Gas Shift reaction 122, and Fischer Tropsch Catalyst process 155 generate heat that in some embodiments of the invention is used to supply steam to the plasma melter 112, or to a turbine generator (not shown), or any other process (not shown) that utilizes heat.

Fig. 3 is a simplified schematic representation of an embodiment of the invention 300 wherein methane product is produced along with algae that is used as a fuel. Elements of structure that have previously been discussed are similarly designated.

In this specific illustrative embodiment of the invention, a portion of the carbon monoxide and hydrogen obtained from pretreatment step 120 is diverted by a flow control valve 150 and supplied to Sabatier Reactor 165. This diverted flow is applied to achieve an appropriate molar ratio of carbon monoxide and hydrogen, and thereby optimize the production of methane. In addition, in this specific illustrative embodiment of the invention, a flow valve 160 diverts a portion of the hydrogen and carbon dioxide that is produced at the output of Water Gas Shift reaction 122 to Sabatier Reactor 165.

Pretreatment step 120, Water Gas Shift reaction 122, and Sabatier Reactor 165 generate heat that in some embodiments of the invention is used to supply steam to the plasma melter 112, or to a turbine generator (not shown), or any other process (not shown) that utilizes heat.

Fig. 4 is a simplified schematic representation of a still further specific illustrative embodiment of the invention, utilizing a Europlasma plasma melter and wherein methane product is produced along with algae that is used as a fuel. Elements of structure that have previously been discussed are similarly designated. In addition, other embodiments can, in light of this teaching, be produced by persons of skill in the art using other forms of plasma melters, such as an InEnTec plasma enhanced melter, or a Westinghouse plasma melter.

As shown in this figure, a carbon dioxide recycling system 400 includes a power plant 201, which in this embodiment of the invention is a conventional coal power plant having a base load, in this specific illustrative embodiment of the invention, of 1830 MW per day. In some embodiments of the invention, however, power plant 201 is powered by natural gas. In embodiments where power plant 201 is a modern coal plant, it will emit on average about 3,458,700 Lbs of carbon dioxide per hour, or about 13 to 18% of its exhaust stream by volume.

Carbon dioxide recycling system 400 additionally is provided with an oxygen enriched coal power plant 202. Oxygen enriched coal power plant 202 issues a higher concentration of carbon dioxide in its exhaust stream, i.e., about 65% by volume. Other industrial plants 203 and 204 are also included in carbon dioxide recycling system 200. Industrial plant 203, for example, includes in this specific illustrative embodiment of the invention an ammonia plant, an H ₂ plant, an ethylene oxide plant, and a natural gas plant. These plants issue a carbon dioxide output concentration of approximately 97% by volume. Ethanol plant 204 is, in some embodiments, a modern plant that issues approximately 99% carbon dioxide by volume.

Carbon dioxide collectors 210 and 211 (or flue gas reactors) are carbon dioxide sequestering systems. Such systems are commercially available from suppliers such as Alstrom. In this embodiment, carbon dioxide collector 210 receives the carbon dioxide output of power plant 201, and carbon dioxide collector 211 receives the carbon dioxide output of oxygen enriched coal power plant 202. The carbon dioxide outputs of carbon dioxide collector 210, carbon dioxide collector 211, plants 203, and ethanol plant 204, are combined, in this embodiment of the invention, as carbon dioxide 219 and delivered to a Sabatier reactor 218. A water gas shift reactor 242 is included in this specific illustrative embodiment of the invention for applications that require maximum hydrogen yield to optimize the methane conversion in Sabatier reactor 218. This will further reduce the greenhouse gas carbon dioxide by increasing the processing capability of the Sabatier reactor. Carbon dioxide waste stack 244 emits "carbon neutral" carbon dioxide since the carbon dioxide will, in some embodiments, be reclaimed from waste.

In a highly advantageous embodiment of the present invention, a plasma enhanced melter 240, which may be of the type known as a Europlasma Plasma Melter, is used generate, inter alia, syngas comprised of CO and H ₂ . Conventional electrolysis can be used in some embodiments to generate hydrogen, but the feed stock of municipal waste 205 with its paid tipping fee and its liberation of significant energy and reclaimed useful materials make the use of a plasma enhanced melter the preferred choice.

Europlasma Plasma Melter 240 generates a net positive outflow of usable energy (ignoring the stored energy in municipal waste) and produces no additional pollution, or carbon footprint. The primary desired output of plasma enhanced melter 240 is hydrogen rich synthesis gas (syngas) that is piped to Sabatier reactor 218. As shown in this figure, the hydrogen rich synthesis gas is delivered in parallel with carbon dioxide 219 to Sabatier reactor 218. In one implementation of the invention, Sabatier reactor 218 is a ceramic foam Sabatier reactor. However, other forms of fuel producing endothermic reactors can be used in the practice of the invention. The close coupling of a sympathetic endothermic reaction is not required, but renders the process more energy efficient. The Sabatier reactor operates to effect the following reaction :

CO ₂ + 4H ₂ = CH ₄ + 2H ₂ O

The primary desired output of carbon dioxide recycling system 400 is methane (CH ₄ ) at the output of Sabatier reactor 218, which is reburned, in this specific illustrative embodiment of the invention, in power plant 201 and oxygen enriched coal power plant 202. Reclaimed metals 214 and silica based construction materials 215 are additional benefits of plasma enhanced melter 220.

In essence, the carbon dioxide that is emitted by power plant 201 and oxygen enriched coal power plant 202 is continuously recycled, bringing its carbon foot print closer to zero and vastly increasing the efficiency of such plants, thereby reducing the amount of coal required per kilowatt-hour of power produced. However, the use of bioreactor 140 in this embodiment can reduce the carbon foot print to less than zero

In some embodiments of the invention, Sabatier reactor 218 is jacketed (not shown) in a steam generating heat transfer system (not specifically designated). Such jacketing is particularly advantageous when combined with the alumina ceramic design of the Sabatier reactor in this embodiment of the invention. The combination of the superior heat transfer of the alumina ceramic material with a steam generator increases the heat recovery efficiency of the system. Steam 217, as well as stored energy recovered from Sabatier reactor 218 is in this embodiment of the invention, returned to power plant 201 and oxygen enriched coal power plant 202, or it can be sold locally to surrounding industries (not shown), or as municipal steam for heating. In this embodiment of the invention, there are provided pressure swing absorbers 232 and 234 (PSAs) that serve to separate the hydrogen from the CO ₂ . A number of other methods such as molecular sieves, and the like can be used in the practice of the invention.

Fig. 5 is a simplified schematic representation of yet another embodiment of the invention showing a primary plant system 500 wherein algae is produced that is used as a fuel. As shown in this figure, a plasma reactor 310 will process a feedstock 312 that in this specific illustrative embodiment of the invention can consist of 100% coal, 100% municipal solid waste (MSW), 100% biomass, or any combination thereof. Other heat sources other than plasma could be used in the practice of the invention. In this embodiment, feedstock coke 315 may optionally be used. Feedstock air, or oxygen enriched air 117 also optionally may be delivered to plasma reactor 110.

Direct or indirect acting plasma torches 320 are used in this specific illustrative embodiment of the invention to excite plasma reactor 310. In a preferred mode of operation plasma reactor 310 is operated in a pyrolysis mode with compressed MSW as the feedstock. However, plasma reactor 310 can be operated in a non pyrolysis mode in the practice of the invention. Additives 322 are optionally delivered to plasma reactor 310 to neutralize the acid or base content (not specifically designated) of a product gas 325 that is conducted along an outlet duct 330. Product gas 325 exits the plasma reactor at approximately 1250° C, and approximately 27% of the total energy that is present in product gas 325 from the plasma reactor 310 primarily is in the form of sensible heat. Due to the extreme temperature and composition of product gas 325, most of the heat energy has heretofore usually been wasted. The present invention includes within its scope several methods of utilizing this energy more effectively. In this embodiment, the heat contained in product gas 325 is recovered in a high temperature heat reclamation system 335

It is shown in Fig. 5 that heated/super critical steam 350 is piped to a steam turbine 300. Steam turbine 300 is coupled to rotate a generator 302 to produce electrical energy at an electrical output 305 that is used to operate plasma torches 320. A further electrical output 307 issues electrical energy that is used to operate miscellaneous process systems (not specifically designated), and a net carbon free electrical output 310 from generator 302 constitutes net power to the distribution grid (not shown).

In a 2,500 Ton per Day (TPD) MSW plant the net continuous carbon free electrical output from this stage would be approximately 31 MW. Spent steam 315 is returned through a condenser 318 and a conduit 370, and is recharged through high temperature heat reclamation system 335, as previously described. In this specific illustrative embodiment of the invention, the spent steam that is conducted through conduit 370 includes steam obtained from a Richardson reactor 340.

It is noteworthy that the generated electrical power is actually carbon negative in this application since the typical make up of MSW contains significant amounts of biomass that captures CO ₂ from the atmosphere prior to being processed in the plasma reactor 310. No additional greenhouse gas credits are produced due to the avoidance of escaping gaseous pollution from landfills. Pure biomass will produce greater power with reduced greenhouse gas emissions. At the other extreme of the feedstock 312 scale is coal with an illustrative BTU content of approximately 14,120 btu/lb. If coal is used as feedstock 312 in a 2,500 TPD plant, the net electrical output 310 of this stage will be approximately 90 MW. This power is carbon free since no exhaust gas is released to the atmosphere in the production of this power. A combination of biomass, MSW, and coal will produce a proportionate amount of net electrical energy 310.

Product gas 325a that has been passed through high temperature heat reclamation system 335 is routed, in this specific illustrative embodiment of the invention, through control valves 330-333 to produce various products. It is to be noted that plant system 500 can employ one or more, in any combination, of reactors 340-343. In addition, some embodiments of the invention are provided with a secondary power generation system 360, wherein the CO and H ₂ that are passed thought control valve 361 is compressed and provided to a secondary gas turbine (not shown) that drives a secondary generator (not shown). In still further embodiments of the secondary power generation system, heat is extracted from the exhaust of the secondary gas turbine and is used to drive yet another turbine (not shown) and further generator (not shown).

Product gas 325a that is issued by high temperature heat reclamation system 335 is routed, in this specific illustrative embodiment of the invention, through a Richardson reactor 340, which in some embodiments is a Fischer Tropsch style reactor. During off-peak electrical generation hours (e.g., at night), a base amount of carbon free, or carbon negative electrical energy is sent to the grid through generator 302. The product gas is directed to make selectively C ₂ , C ₃ , C ₄ , and C ₅ products 350 such as plastic feed stocks through Richardson reactor 340. A small amount of CO product gas 351 is collected and sold for industrial use or product feed stock, such as detergents and polycarbonates. The CO product gas 351 is, in some embodiments of the invention, gas shifted, such as in a water gas shift process 342, to produce more hydrogen and more products 350 with a slight release of carbon neutral CO ₂ or carbon positive CO ₂ , depending on which feed stock 312 is being used.

Product gas 325a is additionally directed to water gas shift process 342, and the shifted CO ₂ and H ₂ are delivered in this specific illustrative embodiment of the invention to pressure swing adsorption processes (PSAs) 334a and 334b. The CO ₂ separated by the PSAs is provided to bioreactor 140 for enhancing the growth of algae 142, as noted above, as well as O ₂ at outlet 144.

Each of reactors 340-343 reclaim any heat possible using steam loops, such as that designated as steam loop 353. The additional steam loops to the balance of the reactors are not shown for sake of clarity of the figure. A Sabatier Reactor 341 produces CH ₄ as its output product. An ammonia process 342 produces feed stock for fertilizer or munitions, and a methanol reactor 343 produces methanol as its output product, specifically CH ₃ OH. In this specific illustrative embodiment of the invention, during peak electrical demand hours reactors 340-343 are bypassed by the closure of control valves 330-333, and product gas 325a is directed to secondary power generation system 360 via a control valve 361. Also, each of reactors 340- 343 is shown to issue some CO, which in some embodiments of the invention, is delivered to water gas shift process 342 (conduits not shown). Although the invention has been described in terms of specific embodiments and applications, persons skilled in the art can, in light of this teaching, generate additional embodiments without exceeding the scope or departing from the spirit of the invention herein claimed. Accordingly, it is to be understood that the drawing and description in this disclosure are proffered to facilitate comprehension of the invention, and should not be construed to limit the scope thereof.
