COSTELLO

 

 

 

 

The Costello process technology features process intensified reactors followed by separation of biodiesel from the glycerin with either centrifuges or phase separators. Next the biodiesel flows to the catalyst and soap removal step and finally to the biodiesel methanol distillation unit. Finished ASTM biodiesel flows to the bulk storage tank. The glycerin in turn flows to the glycerin methanol distillation unit. Recovered methanol from both distillation units flows to the methanol dehydration unit and back to the front end of the process. Recovered crude or unrefined glycerin flows to the bulk storage tank.

Optional process technology can convert the glycerin to high purity glycerin. Additionally glycerin can be partially hydrogenated to propylene glycol or fully hydrogenated to propane gas. These supercritical hydrogenation technologies are offered through our Swedish Technology Partner, Harrod Research.

Harrod Research has build and operated a pilot plant to convert fatty acid methyl esters into higher priced fatty alcohols using their supercritical hydrogenation technology. This technology is also available. The flow sheet and pilot plant are shown above.
