Abstract
A method for processing organic material, in which method bioconversion is performed on the organic material in at least one first reactor, the biogas formed in the bioconversion is treated with ammonia in at least one second reactor and buffer solution produced in the second reactor is recycled to the bioconversion in the first reactor. Thus, the carbon dioxide of the mixed methane/carbon dioxide gas reacts with the ammonia and forms a buffer compound, such as ammonium bicarbonate and/or ammonium carbonate.
Claims33
A method for processing organic material to produce a hydrolysed product and a cleaned biogas, wherein the method employs at least two reactors and comprises the steps of
- a) performing a bioconversion on the organic material in the first reactor;
- b) treating the biogas formed in the bioconversion with ammonia in the second reactor which is pressurized;
- and
- c) recycling buffer solution formed in the second reactor to the first reactor.
