BIOGAS CONCENTRATION METHOD Russian patent published in 2001 - IPC

FIELD: biogas production. SUBSTANCE: invention provides method for concentration of biogas by way of exhausting carbon dioxide by protococcus algae and hydrogen sulfide by photosynthesizing sulfurobacteria on sewage disposal plants belonging to agroindustrial complex. Method involves production of biogas and transporting it from production source to transparent chlorella-generator for treatment by protococcus algae and sulfurobacteria, which is effected by bubbling biogas through clarified mash bed. Clarified water from chlorella-generator is subjected to dynamic and static disintegration of biomass and associates of heavy and light water. Disintegrate is then compacted and subjected to dynamic and static disintegration of associates of heavy and light water. Residual mixture of associates is subjected to electrolysis and alkaline solution after electrolysis is added to mash to increase alkalinity of medium for culturing of protococcus algae and photosynthesizing sulfurobacteria. Integrated utilization of manure and dung using present invention reduces expenses on production of commercial product at agroindustrial complex enterprises improves environmental condition. EFFECT: reduced biogas production cost. 1 dwg
