Computer Controlled Biodiesel Process Unit (EBDC)
PL-527390
The Computer Controlled Biodiesel Process Unit, “EBDC,” performs the conversion of fatty acids from vegetable oils into a high-energy biofuel. This process is structured in two main stages:
- Stage I: Mixing and Reaction with Agitation. This first stage begins by introducing vegetable oil into the main reactor, while the catalyst is prepared separately in a smaller secondary reactor. The catalyst and reagent are then combined, and the mixture is subjected to intense agitation and consistent heating. This process is facilitated by a centrifugal pump for recirculation and an electric resistance heater, both of which are computer-controlled for precision. The stainless steel reactor is equipped with a temperature sensor and level switches, ensuring safe and accurate operation throughout the process.
- Stage II: Product Separation and Washing. After the reaction phase, the primary product (biodiesel) is separated from by-products. This is achieved through an initial biphasic decantation process, which is ideal for immiscible substances like biodiesel and glycerin. Due to its higher density, glycerin settles at the bottom and is extracted through the conical base of the reactor. The biodiesel is then directed to a washing stage, where it circulates through an ion exchange column to remove remaining impurities and water. Finally, the biodiesel is filtered through a diesel filter to ensure purity before being stored.
Additionally, the unit’s performance and biodiesel quality can be assessed using a load cell in the product tank and a titration kit, which includes a pipette and droppers.
The EBDC system is integrated with the EDIBON Computer Control System (SCADA), which provides the main unit, a Control Interface Box, a Data Acquisition Board, and software for process control, data acquisition, and data management to oversee each aspect of production.
