Process for the material and energetic utilization of biogenic residues of potato processing and arrangement for carrying out the process

摘要

Process for the material and energy recovery of biogenic residues from potato processing plants 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 are used as wet fermentation Hefefermentation for bioethanol production and / or methane fermentation for biogas production, that the resulting biogenic residues from the processing of starchy root crops, such as potatoes, sweet potatoes, cassava, tapioca, cassava, in the form of Peelings, starchy white waters, residues from the purification of feedstocks, sludge from the upstream ethanol distillation, aqueous media from the periodic plant cleaning and / or Sch lambing, that the available residues are subjected to a suspending process that is set using additives with dry matter contents of at least 25% in the biosuspension, a dry matter content between 12 and 18%, that the biosuspension produced is subjected to an aerobic hydrolysis process that the biosuspension hydrolyzate produced an anaerobic fermenter system from at least one hydraulically and partially mixed fermenter with initially used and constantly reproducing special culture is supplied that contained in the recovered feedstock potential of plant nutrients as a mixture of the solid phase of the fermentation residues and from the Hemmstoffentfrachtung the Biofiltrate resulting liquid washing media is obtained with high levels of ammonium and sulfur compounds and that the desulfurized, dried and compressed biogas for the coupled production of electrical shear and thermal process energy is used.
