The Ethanol Production Process | Process Systems & Design Blog
Wet milling initially accounted for most of the ethanol fuel production in the United States, but new construction has shifted to dry mills, partly because dry mills cost less to build. Dry-milling plants have higher yields of ethanol. The wet mill is more versatile, though, because the starch stream, being nearly pure, can be converted into ...

If ethanol is the primary product produced, dry mills offer the advantages of lower construction and operations costs, with improved production efficiency. Of the more than 70 U.S. ethanol plants currently being built, only a few are wet mills. The efficiency of ethanol production has come a long way during the last 20 years.
Corn Milling: Wet vs. Dry Milling - AMG Engineering
These dry fractionation efforts always result in co-products with less purity than those produced by the corn wet milling process. Consequently the ethanol yield from a dry grind / dry fractionation process is negatively impacted as the result of fermentable starch exiting the process with the co-products.

Ethanol Production - Dry versus Wet Grind Processing
Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.

DCO coming from dry-mill ethanol plants is viewed more as a co-product. The entire corn kernel is ground up for fermentation, and the oil is spun out later from the syrup. The energy component used to create this co-product is calculated to be much lower than that of a wet-mill plant, therefore allowing it to be a viable feedstock to generate RINs.
