Developing an ethanol plant with a dry fractionation process comes with capital costs of $83.35 million to $84.91 million, less than $1 million more than a process without fractionation. "If you have more capital, you would rather go for wet fractionation," Singh says. Because of the high value of coproducts, ethanol production costs in ...

How is Ethanol Made?
Dry Mill Ethanol Process. In dry milling, the entire grain kernel is first ground into "meal," then slurried with water to form a "mash.". Enzymes are added to the mash to convert starch to sugar. The mash is cooked, then cooled and transferred to fermenters. Yeast is added and the conversion of sugar to alcohol begins.
