What type of tanks can I use for the storage of vegetable oil, methanol (methylate), potassium or sodium hydroxide, biodiesel and glycerine?
You can store the biodiesel, the chemicals and co-products in plastic. You can also use stainless steel which is very high quality (and more expensive). Plastic is obviously less expensive but still of acceptable quality. Plastic degrades with extreme light and many plastics will melt around 140 degrees F (or less). What are the costs of storage tanks? The costs depend upon the material type of tank that you purchase, whether it is the less expensive option of plastic or more expensive option of stainless steel. Circle Biodiesel & Ethanol Corporation can fabricate stainless steel tanks at any size for you.
