EBDC Gerät für den Biodieselprozess, computergesteuert.
The Computer Controlled Biodiesel Process Unit, "EBDC", produces biodiesel fron vegetable oil and allows the user to analyze the process and all the variables involved.
The process carried out by the Computer Controlled Biodiesel Process Unit, "EBDC", consists on transforming the fatty acids contained in vegetable oils into a high energy content biofuel.
Basically, the process consists of two well-defined stages:
- Stage I: Mixing the products with the stirring technique. It consists on combining and stirring the raw materials required to make biodiesel (vegetable oil and a catalyst) under a homogenous heating provided by a computer controlled heating element. This stage is carried out in a reactor made of polyethylene that includes a temperature sensor and level switches to guarantee a safe operation. The stirring consists in recycling the product driven by a computer controlled pump.
- Stage II: Separating and washing the products obtained. A second stage fundamental after the reaction is the separation of the main product from the rest of by-products. It is usually done with a first two-phase decantation, thanks to the conical shape of the reactor, to remove the glycerin and a biodiesel washing through ion exchange resin.
Finally, the efficiency of the unit and the quality of the biodiesel can be assessed thanks to a load cell installed on the unit and a titration kit (pipettes, droppers, etc.).
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
