Biodiesel: Bulk Separation of FAMEs and Glycerin By-product

NO PRODUCTS AVAILABLE IN YOUR COUNTRY

One of the later steps in the manufacture of biodiesel is the separation of FAMEs and glycerin by-product into two fractions. The FAME fraction is then further purified for use as fuel. Residual glycerin not only lowers the FAME concentration (biodiesel quality), it can also damage automotive engine components. DOWEX DR-G8 dried cation exchange resin is designed as processing aid to reduce and remove trace levels of glycerin, salts, soaps, and other organics from crude biodiesel streams.
