Method for the production of ethanol from corn fibers. Invention relates to a process for the preparation of ethanol from a corn fiber containing feedstock by using a set of process steps specifically identified for the treatment of the said feedstock. It particularly relates to the use of a soaking followed by mix acid and enzyme treatment that release fermentable C5 and C6 sugars from said feedstock. It further relates to using a recombinant yeast to convert both C5 and C6 sugars to ethanol.

Method for the production of ethanol from corn fibers

The present invention relates to a system and method for distillation to reduce steam consumption has been disclosed. The system comprises of an analyser column, multiple pressure booster units (fan set-I, fan set-II, and fan set-III), a rectifier column, a plurality of evaporator units (), a splitter unit, a plurality of de-superheating units (), and additional DDGS dryer unit. The integration of pressure booster units (fan set-I, fan set-II, and fan set-III) and additional DDGS dryer unitincreases the steam (vapor) production and reduces the steam (vapor) consumption in the system from external source and balances the optimization of process energy requirements, energy cost, and process carbon intensity.
