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

摘要

Process for the material and energy recovery of sugarcane processing residues, including the removal of ready-to-eat sugar cane and sugar cane straw and cane straw from the sugarcane plantation, crushing and pressing of the crop in the processing plant, intermediate bagasse bagging, bagasse energy recovery for electric energy and process steam production, the Rohsaftreinigung with the recovery of Pressmud and the Zuckersafteindickung with the recovery of crystalline sugar and molasses, characterized in that at least parts of the costs incurred in the sugar cane processing bagasse, the Pressmuds and / or other liquid and solid residues of sugar cane processing be ensiled together that shares of the resulting bagasse and other solid residues of Zukerrohrverarbeitung and / or silage from the ensiling process comminuted to millbase with fiber lengths of less than 10 mm that the biosurfactant is hydrolyzed separately from the fermentation, that the hydrolyzate obtained in the hydrolytic treatment is fermented in the mesophilic medium using culture-conserving fermentation techniques, that the biosuspension is produced together with press mud and liquid process media anaerobic methane fermentation is maintained over a minimum treatment time of at least 15 days, that at least the biogas produced during the fermentation are biologically desulfurized separately from the fermentation, that the fermentation residues in a solid phase with an average of 30% dry matter content and biofiltrate with less than 6 % Dry matter content are separated and that the biofiltrates are used proportionately or completely for the production of a biosuspension from the residues of sugarcane processing.
