Production of Biodiesel with LEWA Pumps

Solution

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 producing biodiesel with LEWA ecosmart pumps for metering of additives (up to 300 l/h, up to 80 bar, ambient temperature)
Alternative process for producing synthetic fuels with LEWA ecoflow or LEWA triplex as high-temperature process pump for increasing reactor pressure (15 m³/h, up to 250 bar, up to 350 °C)
Esterification of organic fats or oils with methanol in the high-pressure process with LEWA triplex, process pump as feed pump for oil or methanol, (100 to 2400 l/h, up to 250 bar, up to 100°C)
Thermal decomposition of organic waste with a LEWA metering pump as feed pump for biomass (100 l/h, up to 320 bar), ambient temperature and a recirculation pump (250 bar, 350 °C)
Newly developed synthesis process for the Bioliq^® pilot system at KIT Karlsruhe with various LEWA metering pumps and high-temperature pumps

Process description

Process

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

Background

The use of biofuels offers significant advantages in comparison to fossil energy sources:

Environmentally friendly by reducing CO₂ emissions in accordance with the Kyoto Protocol
Excess capacities of industrial agriculture can be used sensibly
Political independence from oil states, global availability of the raw material
Can be used with current and future engine technology, because production of a synthetic fuel can be "customized"
