Historically, the high cost of enzymes has outweighed any benefits they might offer, such as their ability to convert low quality, high free fatty acid feedstocks, savings on energy consumption, and co-production of technical grade glycerin. Recently, the hurdle of making the process economically viable on a commercial scale has been overcome. Biodiesel Refining The use of enzymes results in a crude biodiesel with 1.5 - 2.0% unreacted FFA. Viesel initially used a caustic wash to turn this FFA to soap, followed by washes and centrifugation to remove the soap and water. The recovered soap was acidulated back to FFA, for re-use as a blend component in the feedstock Viesel has most recently adopted the use of resin technologies; both as a catalyst to convert FFA to FAME and in an ion exchange capacity to adsorb any remaining FFA. The optimization of resins makes the refining process simpler, reduces yield loss, and has allowed Viesel to transition to a continuous flow process for the biodiesel refining section of the plant. Viesel will further develop the capability to convert the current batch enzymatic reaction process into a continuous process throughout 2014.
