19 Molasses Distillery Molasses Storage Fermentation Distillation Dehydration Evaporation Bio-methanation Storage Bio-Composting Evaporation Turbine Slop Boiler WTP, ETP, CT

20 Possibilities of Heat Integration & Effluent Reduction

21 Fermentation Steam Required (kg/lit) of Total Alcohol Spent Wash Generation (KL/KL) Alcohol % (v/v) in Fermented Mash Alcohol % (v/v) in Fermented Mash Alcohol % in Fermented Mash

22 Possibilities in Distillation Spent lees from various process columns can be used for pre-heating various column feed Flash steam from steam condensate pot can be used to drive columns with moderate energy requirement (DFOC / DAC) Fermented mash can be pre-heated using distillation column vapour through beer-heater. Also reduces load on CT Fermented mash can be pre-heated using hot spent wash using PHE Maximum column to be kept under vacuum to reduce steam consumption and scaling; hence increased plant uptime

23 Possibilities in Distillation Atmospheric Hydro column vapour can be used to drive atmospheric De-methanol column Pre-rectifier column can be kept under pressure and vapour can be used to drive both Hydro and De-methanol column Distillation vapour can be used for heating evaporation calendrias wherever possible. Also reduced CT load All feed streams such as RC feed, Hydro feed etc. to be preheated using waste streams Minimum use of DM water for dilution

24 Possibilities in Evaporation Increasing number of effects reduces steam consumption Improvement in design, CIP, use of stand by effects and process control to minimize downtime, thereby reducing energy loss in startstop process Integrating evaporation plant on various waste vapour from Distillation Automated CIP reduction in water requirement
