Patent ID: 8192696

Claim:
A system for the production of purified fatty acid methyl esters (FAME), the system comprising: a feedstock treatment section for receiving and processing an input feedstock to produce waste oil and input feedstock by-products; a transesterification and glycerol separation section for receiving the waste oil and an input methanol feedstock and reacting the waste oil and the input methanol feedstock via a transesterification process to produce a raw FAME mixture and raw glycerol; a glycerol purification section for receiving and processing the raw glycerol to produce pure glycerol and methanol; a waste by-products recycling section for receiving and recycling the methanol into the transesterification process; and a FAME separation and waste by-products recycling section for receiving and processing the raw FAME mixture to produce purified FAME, FAME impurities and FAME by-products, wherein the waste by-products recycling section is further for receiving and recycling the FAME by-products back into the transesterification and glycerol separation section for re-use by the transesterification reaction process, and wherein said waste by-product recycling section is further comprised of: a methanol recycling section receiving and recycling methanol turning it back to the transesterification and glycerol separation section for use in the transesterification reaction process; and a waste oil recycling section for receiving and recycling un-reacted waste oil by returning it back into the feedstock treatment section to be used in the transesterification reaction process.
