Standardized Modular System Oecosys 4000 for the Production of Biodiesel with a Capacity of 3600 tons p.a.
Basic Components
Lohrmann International provides a standardized technology for the efficient and safe production of BioDiesel.

An important prerequisite for the esterification process is an excellent (or good) vegetable oil quality. To guarantee such quality, we recommend the use of a reliable oil press as follows:

Net-Weight: 9200kg
Installed Power: 45kW
Scope of Supply:
- 2 worm extruders – Type Oecosys 15/45

The whole process runs in a single tank and is completed after six to eight hours, depending on the quality of the input material. The plant technology is controlled automatically by means of a programmable logic controller (PLC). The process is visualised on a touchscreen monitor. The operator thus has the plant status in his sight at all times. Continuous data recording ensures the process control and reproducible process parameters, consequently minimising the labour and monitoring work. The process can also be telemonitored by means of a data teletransmission system.
- A defined mass of vegetable oil (triglyceride) or fat is drawn intto the central stainless steel process tank where it is heated.
- Methanol and a catalyst are added to the heated product. The transesterification process can then start.
- The glycerine formed settles compactly at the bottom of the tank and will be drawn off.
- The raw biodiesel is washed with water in order to remove impurities.
- The water settles at the bottom of the tank within a short period and is drawn off.
- The process tank is heated for distillation, completely removing the water and methanol that have not settled in the tank under a vacuum.
- The finished biodiesel is drawn off and pumped into the storage tank. The cycle can start again from the beginning.
