Biofuels are made from renewable energy sources, which are inexhaustible by human standards.
Biodiesel, bioethanol and pure vegetable oils are already being used today in large volumes. The production of synthetic fuels from biomass is being tested in the first pilot systems.
Already at an early stage LEWA supplied several pumps for this development of 2nd generation biofuels to research companies.
LEWA pumps are used in a wide variety of processes for the production of biodiesel and other biofuels.
Depending on the particular application, different pumps that optimally meet the respective requirements are used:
Conventional process for biodiesel production: Esterification of vegetable oils with methanol.
Low pressure 1st generation
Alternative process for synthetic fuel production:
Gasification of carbon-containing raw materials for the production of synthetic gas (CO+H2), which is subsequently converted into a long-chained fuel using Fischer-Tropsch synthesis. In the last process step (hydrocracking), the desired BTL fuel (synfuel) is generated at temperatures < 200°C and a process pressure up to 90 bar.

High pressure 2nd generation
Similar process (conventional)
Esterification of organic fats or oils with methanol in a high-pressure process.
High pressure 2nd generation
Thermal decomposition of organic waste for the production of crude oil with a low boiling point as well as gas with a high hydrogen content.
High pressure 2nd or 3rd generation
The use of biofuels offers significant advantages in comparison to fossil energy sources:

Crude oil must be cleaned, separated, and converted (refined) until the final products suitable for sale are made (e.g., gas, diesel, heating oil, lubricants, propane, butane). LEWA supports you with pumps and metering systems, which are used in the refining process during chemical metering. Application with our products are distillation plants, coker, cracker, or visbreaker, for example. Ask our experts for more information!
