Process for the material and energetic utilization of biogenic residues of bioethanol recovery plants and arrangement for carrying out the process

摘要

Process for the material and energetic utilization of biogenic residues of bioethanol production by using the residues in a wet fermentation, by concentrating the total nutrient potential in the form of nitrogen, phosphorus, potassium and sulfur in a fertilizer fraction obtained from the fermentation residues, and by providing the desulfurized biogas for the energetic Utilization, characterized in that the resulting biogenic residues from the distillery process, such as vats, filter dusts, aqueous media from the periodic cleaning plant and fusel oils, a suspending process are subjected to that using additives with dry matter contents of at least 25% in the bio-suspension a dry matter content between 12 and 18% is set, that the produced biosuspension is subjected to an aerobic hydrolysis process, that the hydrolyzate produced from the biosuspension an anaerobic fermenter system of at least a hydraulically and partially mixed fermenter with initially used and constantly reproducing special culture is supplied that contained in the recycled feedstock potential plant nutrients as a mixture of the solid phase of the fermentation residues and resulting from the Hemmstoffentfrachtung the Biofiltrate liquid washing media with high levels of ammonium and sulfur compounds is obtained and that the desulfurized, dried and compressed biogas is used for the coupled production of electrical and thermal process energy.
