A process for producing ethanol by evaporative distillation comprising: a. preheating a fermented wash to about 60 °C in heat exchanger forming a first stream; b. subjecting said first stream to a degasifying column, wherein said degasifying column removes gaseous part of said fermented wash, forming a second stream and a first vapour stream; c. condensing and collecting said first vapour stream in a collection tank forming a high ethanol stream; d. subjecting said second stream to a first evaporator forming a second vapour stream and a depleted ethanol stream; e. condensing said second vapour stream using a second evaporator forming a third stream and collecting it in said collection tank forming said high ethanol stream, wherein said second evaporator is energized using said second vapour stream; f. supplying a small part of said second vapour stream to said degasifying column as heat source to run said degasifying column; g. subjecting said depleted ethanol stream to a mash column through heat exchanger, wherein said depleted ethanol stream is used to preheat said fermented wash, and then via second heat exchanger, where it gets heated to higher temperature, forming a third vapour stream and a spent stream, wherein said mash column is operated using steam energy as necessary; h. condensing said third vapour stream using said first evaporator forming a fourth stream and collecting it in said collection tank forming said high ethanol stream, wherein said first evaporator is energized using said third vapour stream; i. supplying said spent stream to said second evaporator and concentrating it to form a concentrated spent stream and a process condensate stream, wherein said spent stream is used to preheat said depleted ethanol stream to about 80 °C in heat exchanger; and j. subjecting said high ethanol stream to a rectification process to recover rectified ethanol. a. preheating a fermented wash to about 60 °C in heat exchanger forming a first stream; b. subjecting said first stream to a degasifying column, wherein said degasifying column removes gaseous part of said fermented wash, forming a second stream and a first vapour stream; c. condensing and collecting said first vapour stream in a collection tank forming a high ethanol stream; d. subjecting said second stream to a first evaporator forming a second vapour stream and a depleted ethanol stream; e. condensing said second vapour stream using a second evaporator forming a third stream and collecting it in said collection tank forming said high ethanol stream, wherein said second evaporator is energized using said second vapour stream; f. supplying a small part of said second vapour stream to said degasifying column as heat source to run said degasifying column; g. subjecting said depleted ethanol stream to a mash column through heat exchanger, wherein said depleted ethanol stream is used to preheat said fermented wash, and then via second heat exchanger, where it gets heated to higher temperature, forming a third vapour stream and a spent stream, wherein said mash column is operated using steam energy as necessary; h. condensing said third vapour stream using said first evaporator forming a fourth stream and collecting it in said collection tank forming said high ethanol stream, wherein said first evaporator is energized using said third vapour stream; i. supplying said spent stream to said second evaporator and concentrating it to form a concentrated spent stream and a process condensate stream, wherein said spent stream is used to preheat said depleted ethanol stream to about 80 °C in heat exchanger; and j. subjecting said high ethanol stream to a rectification process to recover rectified ethanol.
