SRS & BEI Partner to Develop Enzyme Catalyst Transesterification
SRS and Biodiesel Experts have developed a transesterification system for biodiesel production process that utilizes enzymes efficiently to produce quality biodiesel on any scale. While using high-FFA feedstock, the primary job of the enzyme becomes the conversion of FFA to FAME. The enzymes are able to convert high-FFA feedstock with reaction chemistry into FAME by performing both transesterification and esterification simultaneously.
SRS and Biodiesel Experts have developed a transesterification system for biodiesel production process that utilizes enzymes efficiently to produce quality biodiesel on any scale. While using high-FFA feedstock, the primary job of the enzyme becomes the conversion of FFA to FAME. The enzymes are able to convert high-FFA feedstock with reaction chemistry into FAME by performing both transesterification and esterification simultaneously. This occurs in two steps. (1) The glycerides are first hydrolyzed to FFA (2) The FFA and methanol are esterified to produce FAME. Careful monitoring during the reaction of methanol, water and enzymes, temperature, and rate of conversion are critical to ensure high-quality finished biodiesel and optimize the number of enzyme reuses.
“We are excited to be working with Biodiesel Experts. Incorporating their enzymatic technology into our biodiesel refinery processes is an important milestone to add to our current technologies,” said George Hawranik, Senior Engineer of SRS International. “The hurdle of making enzyme catalyzed transesterification economically viable on a commercial scale has been overcome. The enzymatic process works at a production cost per gallon that is comparable to that of traditional biodiesel, requires lower capital investment, allows the use of less expensive, more varied feedstocks with free fatty acid content as high as 100 percent and the enzymes are immobilized so they can be used for long periods without replenishing, making it economically feasible.”
SRS International looks forward to continued expansion in their relationship with Biodiesel Experts and to ultimately increase the product scope and utilization of enzymatic biodiesel process systems.
“Working with SRS International has been an amazing experience,” said Ernie DeMartino, President of Biodiesel Experts. “They (SRS International) have proven biodiesel technology and process equipment. Incorporating our enzymatic process knowledge will revolutionize the biodiesel industry by allowing producers to cut production costs and allowing them to use up to 100% FFA feedstock. We are looking forward to offering this new process.”
