7.3b: How Corn is Processed to Make Ethanol

912· The main products of dry milling are ethanol, CO 2, and dried distiller grain with solubles (DDGS). Let's go through each of the steps in the dry grind process. GHG Analysis of Dry Mill for Corn Ethanol Production under IRA,The system boundary diagram for corn to ethanol as represented in the GREET model is shown in Figure 2. Corn is harvested, collected, and transported to a biorefinery.

Ethanol Production Dry versus Wet Grind Processing

Traditionally, ethanol from corn has primarily been produced through dry and wetmilling processes. The majority of U.S. ethanol production is from drygrind technology. The Schematic of modelled corn ethanol dry mill process for , typical process flow diagram for a corn ethanol refinery is shown in Figure 1 [11, [21] [22] [23] [24] [25].
