SYSTEM FOR PRODUCING ENERGY FROM SEWAGE AND DOMESTIC AND AGRICULTURAL WASTE BY INTEGRATING FOUR APPARATUSES

WIPO Patent Application WO/2017/134505

Kind Code:

A1

Abstract:

The present invention relates to a system for producing energy from sewage and agricultural and domestic waste by means of four apparatuses. The waste or product from each apparatus is used as feedstock or a catalyst in a process carried out in one or more other apparatuses. The system consists of a digestor (1) by means of which biofuel is produced, the digestor being supplied with sewage and a diluted acid. This process produces biofuel, which is supplied to a power generator (3) that produces electrical energy and exhaust gases that are used to supply a gas generator (2) with heat and oxygenated gas. The gas generator (2) is also supplied with domestic waste, waste from the digestion process and agricultural waste, to produce activated charcoal, ash and synthesis gas that is purified to obtain tar. The purified synthesis gas is subsequently cooled in two stages. The first stage is performed in a pretreatment tank (9) the heat being used in the hydrolysis of the agricultural waste, and the second stage of cooling is performed in a radiator (4). Approximately half of the cooled synthesis gas is supplied to the power generator (3) while the remainder is converted into biodiesel. A solvent and catalyst are added to the agricultural waste, which is previously converted into glucose by means of hydrolysis in the pre-treatment tank (9), and said agricultural waste is then pumped to a reactor (6) to produce hydroxymethylfurfural. Part of the compressed synthesis gas is heated, and the hydroxymethylfurfural is subsequently purified of the solvent and the remaining biomass is pumped to the gas generator (2).
