What is “Pretreatment” and why is it needed?
If feedstock contains FFA (Free-Fatty Acids) in excess of 1%, it is recommended that it be pretreated. Pretreatment options include (Acid Esterification or Caustic Stripping). SRS has designed an exclusive system (FSP-Series/Continuous Flow Acid Esterification System) which utilizes the proven method of using Methanol and Acid to convert FFA into usable oils as opposed to simply caustic washing them out leaving a considerable yield loss. SRS further adds to this process a proprietary process of utilizing a modified waste additive to remove excess water from the oil prior to a transesterifcation process to further prevent the development of soap production. Through the use of proprietary technology, (The SRS FSP-Series Unit) it is now possible to convert feedstocks containing up to 15% FFA into usable fuel, eliminating soap production, and provide a 100% yield even with the most inferior oils.
What technologies does SRS employ to be able to guarantee the performance of the FSP?
While the specifics are proprietary, SRS has engineered the FSP to use heat, pressure, static mixing, and special dosing methodologies to obtain optimal conversion rates at flow rates from 500K-150 million gallons per year.
SRS’ proprietary pretreatment unit is less expensive than other units that are designed to remove the FFA saving you lost volume and money and allowing you to render the FFA to salable oils. This increases product yield and bottom line profit. Without the pre-treatment/esterification process, a BioDiesel plant will operate with little to no profit margin.
The FSP-Series unit represents a complete package capable of handling all of your Biodiesel Engineering needs at a competitive price. The FSP is currently being integrated into numerous existing operational and unoperational Biodiesel plants throughout North America and are an essential component of an SRS BioDiesel “Turn Key” Plant.
