Ethanol byproduct cleanup is generally less technology- and equipment-intensive than other sources. In the USA those include 21 ammonia plants, 18 reformer refineries, 15 natural sources and a handful of others such as flue and natural gas
Today 48 american ethanol plants also supply CO2 for the merchant market. The product is shipped in 105 ton rail cars as well as in 24 ton trucks as well as in small 20 pound cylinders. The location of a plant is very important if it will stable also to produce CO2 for the market. In US midwest is the market is saturated but new facilities are added in other regions.
