At Green Energy Chemicals, we leverage advanced dry milling technology to convert corn into ethanol, embodying efficiency, and sustainability in our process. Starting with the transportation of corn from the silo to the milling phase, where it is ground, our method meticulously blends the corn with water in a tank. This mixture is then heated, with enzymes and other substances added to initiate the biochemical transformation.
The process continues with fermentation, where the mixture undergoes recycling, and additional enzymes are added to facilitate the conversion of glucose into alcohol. This reaction naturally generates heat, necessitating careful temperature control to ensure optimal conditions for the alcohol to reach the desired concentration.
Following fermentation, the mixture enters the distillation unit. Here, in our eight-column system, we meticulously remove impurities and unwanted materials, resulting in Extra Neutral Alcohol (ENA) with a purity of minimum 96%. The ENA is then transferred to stainless steel storage tanks for further use.
The carbon dioxide released during fermentation is captured and stored in a separate unit with 99.9% purity to be converted into liquid carbon dioxide.
The solid residues obtained from the distillation process undergo decantation, evaporation, and drying to produce Distillers Dried Grains with Solubles (DDGS), a feedstock that provides a high protein source for animals. In addition, valuable distilled corn oil, a biofuel, is also produced at this stage.
