Dehydration Technology Ethanol Production– Technologies Molecular Sieve (MS) - Technology of 90s Azeotropic Distillation(AD) - Old Polluting Technology Membrane - Yet to be stabilized - Membrane life Molecular Sieve technology under licensefrom US firms – Pressure SwingAdsorption (PSA) process Low steam consumption of 0.6 kg per L ofEthanol & long life of Mol sieve established– ahead of Brazil Higher level of Instrumentation andDCS/PLC systems being introduced inalmost all in new plants
Effluent Treatment & Utilities Distillery Effluent very rich in organic matter– very high BOD and COD Major Issue & also an opportunity to use richhumus and nutrients in effluent Zero effluent discharge Primary Effluent Treatment Bio-methanation Bio-composting using press mud from sugarmills and distillery effluent Reverse osmosis/Evaporation being used toreduce quantity of effluent, increase DS andreduce water consumption by recycling Incineration in Boilers or spray drying High Water use issues –being being addressed
