Also known as grain alcohol, ethyl alcohol, or ETOH, ethanol is typically produced from corn, wheat or barley by a fermentation process. Ethanol is bio-degradable and in the case of spills, readily degrades.

Containing about 35% oxygen, ethanol burns cleanly and cooler than gasoline, is used in certain racing engines and is rapidly growing in demand. When added to gasoline in the range of 5 to 10%, it increases the octane and oxygen content by 3.5% thus reducing smog forming emissions and greenhouse gases. It also cleans and reduces or prevents engine deposits and mixes well with any entrapped water in the gasoline and acts like a gas-line antifreeze. Because of this propensity to attract water it is common to blend the ethanol in gasoline close to the end-user.

PMEC has designed, installed and commissioned numerous blending systems for the injection of ethanol into gasolines at product loading racks including skid mounted unit and rack modifications that are completed with minimal interruption to the operations.
