BioDiesel Plant

Lastingly Regenerating Raw Materials – an Infinite Energy Source!

BioDiesel belongs to the renewable energies. Raw materials for BioDiesel are regenerating and in principle don`t create environmental damages. Thus it offers the solution for two main problems in the traffic sector:

Best reasons for shifting to BioDiesel production and commercial application: Worldwide limited energy resources and global climatic change.

The high demand for Diesel fuel in Europe and the rest of the world and the increasing price for crude oil, carry the production of bio diesel in the foreground and make it economically attractive for investors.

Lohrmann International provides a standardized technology for the efficient and safe production of BioDiesel.

Advantages of Lohrmann BioDiesel Packages

The Bio Diesel Plant

The Modern Technology of Transesterification

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 control (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.

Flexibility of the BioDiesel Plant Capacity

So far, it has only been possible to cover the costs for transesterification of vegetable oils and natural fats to produce BioDiesel by producing on a large industrial scale. Thanks to the intelligent design of the Lohrmann BioDiesel Packages, it has now become possible to eliminate cost-intensive parts without affecting the quality of the produced fuel. Therefore, the decentralised plant with a lower capacity of BioDiesel can for now be operated very profitably. No specialised knowledge is necessary to operate these plants. They run fully automatically under PLC control 24 hours a day.

Two plant sizes with annual capacities of 1800 and 3600 t p.a. BioDiesel are available. Capacity extensions are simple and easy by doubling or mutiplicating in parallel operation.

 

In Seven Steps to Tank-ready BioDiesel

1. A defined mass of vegetable oil (triglyceride) or fat is drawn into the central stainless steel process tank where it is heated.

2. Methanol and a catalyst are added to the heated product. The transesterification process can then start.

3. The glycerine formed settles compactly at the bottom of the tank and will be drawn off.

4. The raw BioDiesel is washed with water in order to remove impurities.

5. The water settles at the bottom of the tank within a short period and is drawn off.

6. The process tank is heated for distillation, completely removing the water and methanol that have not settled in the tank under a vacuum.

7. The finished BioDiesel is drawn off and pumped into the storage tank. The cycle can start again from the beginning.
