Abstract
A system and process for continuous production of fatty acid methyl esters (FAME) from the fatty acid triglycerides of waste oil via transesterification in the presence of a reusable sugar-based catalyst. The system and process incorporates re-cycling and re-use of waste bi-product streams to result in a near-zero emissions, with a 97% product yield mix consisting of almost pure biodiesel and a very small percentage of impurities including glycerol.
Claims29
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 bi-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 bi-product recycling section for receiving and recycling the methanol into the transesterification process;
- and
- a FAME separation and waste bi-product recycling section for receiving and processing the raw FAME mixture to produce purified FAME, FAME impurities and FAME bi-products,
- wherein the waste bi-product recycling section is further for receiving and recycling the FAME bi-products back into the transesterification and glycerol separation section for re-use by the transesterification reaction process.
