Ethanol Fuel Storage Tanks

Ethanol Storage TankEthanol, an alcohol-like substance, is manufactured from corn, sugar cane, and other farm-grown plant sources.  Ethanol helps gasoline burn cleaner, reducing toxic air emissions; and because it can be produced from United States based agricultural sources; it reduces our dependency on petroleum imports and helps boost the economy as well. At Envirosafe Tanks, we produce double wall steel fuel storage tanks that are perfectly suited for the safe storage and dispensing of ethanol.

Ethanol Tanks: Tips for Safe Fuel Storage:

  • Speak with your consultant and ensure that your tanks, pumps, probes, and dispensers are compatible with ethanol-blended fuels.
  • Before the delivery of ethanol blended fuel, check your storage tank system for water and completely remove all moisture.
  • Keep a close watch on your systems for water and clogged filters during normal operations, especially after fuel deliveries, when water and filter problems can most easily occur.
  • In order to ensure quick removal of water in tanks, be sure to have a quick response plan in place.
  • When checking for water in ethanol-blended fuels, use the correct type of paste.
  • To reduce the chance of water infiltrating your system, ensure that all tank fill port seals are tight and that there is no pooling water on top of your tank’s associated manhole covers.
  • For E10 ethanol blends, install 10-micron filters on dispensers and 1-micron filters for E85 blends.
  • Always remember to advise your insurance carrier as to which tanks are being used for ethanol blended fuel storage.
  • Never use plated metal tanks
  • Never use aluminum tanks
  • Be certain hoses and all other rubber components are ethanol compatible

By implementing the above procedures, you can ensure quick and efficient delivery, storage, and dispensing of your ethanol blended fuels. In general, Ethanol is compatible with almost all aboveground fuel storage tanks, however high percentage ethanol blends such as E85 can corrode aluminum and certain grades of plastic and rubber.  Ethanol is actually more forgiving of water within a tank because it absorbs a small percentage of the moisture.

Ethanol Fuel Storage Tanks: About Ethanol

Ethanol is a high octane fuel produced from starch, sugar, or cellulose based feedstock. It is most easily derived from corn and sugar cane, but can also be made from grass, wood, crop residue, and old newspapers.

This high octane fuel prevents knocking and blending it with low octane gas to achieve a standard 87 octane rating is commonplace. Ethanol has gained such popularity that many automotive manufacturers produce vehicles that can use E85, an 85% ethanol blended fuel.

Ethanol is extremely easy on the environment producing markedly less air pollutants than gasoline, and it is fully sustainable within the United States of America. This means a reduced reliance on foreign oil producers by the U.S.
