Biodiesel fuel is produced by the Transesterification of biological materials. Relative to standard diesel fuels, biodiesel produces significantly less carbon dioxide, making a major contribution to a healthier ecosystem.
Eslinger Biodiesel is using an emerging feedstock that is less costly than soybean oil with equivalent or better cloud point characteristics.
Enzyme Process: The lower temperatures needed by the enzyme process will result in 62.5% less heat used. This plant also has numerous heat exchangers and a closed loop hot oil heating system that reduces emissions and our energy consumption by recycling surplus heat.
The Novazymes process is new but proven in several plants across the country. Our engineering group followed the Novozymes protocols exactly and then added extra features to actually speed up our reaction times. Other inovations include how we deliver the enzyme, how it is mixed to enhance and how we heat the system. In this fully automated plant, our process engineers in the control room have a number of options to assist in the conversion of low grade feedstock that will exceed ASTM quality standards. Most importantly, the reactor design offers a reverse process that enables the plant to use the traditional sodium methylate approach if we choose.
The entire plant is heavily oversized, with the latest process technologies including secondary FFA reduction (if needed) and distillation columns for both our biodiesel end-product and our glycerin by-product. The Eslinger Bio-refinery is a fully optioned and oversized plant designed to process any quality level of feedstock into a clear ASTM certified B-100-D product.
