CDMS EthaMem G1: Advanced Ethanol Production Technology
Whole ethanol production process has four major units.
- Fermentation
- Distillation
- Dehydration
- Spent wash Treatment
CDMS precisely identifies the short fall of each unit and systematically replaces conventional low performing technology with high performance.
Process Highlights
2.1 Feed Water Treatment
Use of Ultra filtration Membrane for raw water treatment This will remove unwanted micro-organism present in feed water that might affect fermentation process.
2.2 Fermentation Unit
Use of the Oxygen enrichment membranes in aerobic process which helps to increase the fermentation rate and to reduce the process time.
2.3 Distillation Unit
Use of high efficiency Chemdist made contact material (column internals/packings) for improving distillation performance.
2.4 Dehydration Unit
Use of high life and high efficiency Pervaporation membranes for ethanol concentration/dehydration from 95% to 99.99%. This membrane dehydration unit gets rid of the high opex Azeotropic distillation or the high maintenance molecular sieve unit. The membrane life is in the range of 5-7 years.
2.5 Spent Wash Treatment Unit
Use of CDMS’s Membrane Distillation (MD) system replaces high opex multiple effect evaporator (MEE) and/or reverse osmosis system. Our MD unit is compact, highly energy efficient.
2.6 Turbulators
Turbulators is our patented heat exchanger insert used to enhance the heat transfer efficiency up to 30-40%
