Title:
A METHOD FOR PURIFYING LIQUID HYDROCARBON MOTOR FUELS FROM SULFUR AND FOR FURTHER REDUCING THE SULFUR DIOXIDE CONTENT IN EXHAUST GASES UP TO ZERO DURING COMBUSTION OF THE FUELS
Document Type and Number:
WIPO Patent Application WO/2019/139558
Kind Code:
A1
Abstract:
The invention relates to the oil-refining industry, in particular, to methods for purifying a fuel from sulfur-containing compounds. The method for purifying liquid hydrocarbon motor fuels from sulfur and for further reducing the sulfur dioxide content in exhaust gases up to zero during combustion of the fuels by modifying the sulfur-containing fuel molecules in a fully-developed cavitation mode, by separating the sulfur-containing modified molecules from the remainder of the fuel molecules on polymer membranes and by activating the fuel purified up to 20 ppm in the fully-developed cavitation mode prior to the combustion. What is novel is that the reduction of the sulfur content in the fuel is achieved by means of treating the fuel or a fuel fraction in the fully-developed cavitation mode with addition of a hydrogen peroxide aqueous solution and/or a strong aqueous solution of iron oxides to the fuels, followed by separating the obtained emulsion into a fuel fraction and a water-paraffin emulsion, followed by separating the fuel fraction on the membranes under the temperature of from 90°C to 180°C under the atmospheric pressure into a fuel fraction having a low sulfur content and a fuel fraction having an increased sulfur content. Reduction of the sulfur dioxide in the exhaust gases during combustion of the purified fuels up to zero by means of activation of the fuels having the low sulfur content in the fully-developed cavitation mode is performed without addition of other chemical substances. Production of a reduced oil-water emulsion from the water-paraffin emulsion and the fuel fraction having the increased sulfur content that increases the efficiency of reduced oils combustion is performed in boiler units. Reduction of the sulfur content in the fuel or fuel fractions is performed up to the required level of 20 ppm or less. Treatment of the initial fuel or fuel fraction by the cavitation is performed under the pressure of 1.0-.5.0 atm and the temperature of 20°C - 70°C.
