SYSTEM FOR THE CONCENTRATION OF DISTILLERY SPENT-WASH AND METHOD OF DISPOSAL OF THE SAID SPENT-WASH CONCENTRATE

摘要

System for the concentration of distillery "spent-wash and method of disposal of said "spent-wash" concentrate comprises of:(i) generating steam and using it for running a turbo-alternator and utilizing the exhaust steam therefrom for evaporation of ''spent-wash'' in a multiple-effect evaporator; alternatively, using live steam for re-compressing the vapour from first body of said multiple-effect evaporator into the calandria of the same body by means of a thermo-compressor;(ii) concentrating ''spent-wash'' in a multiple-effect evaporator;(iii) flashing condensate from one effect to effect of the evaporator set;(iv) using flash vapour from the last condensate of the multiple effect evaporator to concentrate the product from the evaporator, into a vacuum pan;(v) utilizing the vapoure exhausted from the last body of said multiple-effect evaporator set of the system for distillation columns of the distillery for the recovery of alcohol from fermented wash thereby avoiding the use of live stem for-the distillation of alcohol; and(vi) mixing ''spent-wash'' concentrate with an absorbent material like dry bagacillo or dry filter-mud (both of which) are obtained as by products in a cane-sugar factory) and which is convenient for handling, transport and disposal.
