LPG, Butane en Propane

LPG stands for Liquefied Petroleum Gas.

LPG is widely used as a fuel in mixture engines for cars, forklift trucks and boats, among others. LPG is a mixture of propane (C3H8) and butane (C4H10). Depending on the usual outside temperature on site, the two gases are mixed in a certain ratio. Propane evaporates from −40 degrees and butane from about 0 degrees Celsius. More butane is used at higher temperatures, while at lower temperatures more propane is added to the mixture because butane does not evaporate enough at low temperatures.

Mixtures of propane and butane are also used as aerosol propellant, using the ratio of propane to butane to achieve the desired vapor pressure.

It is also possible to cook on LPG, after refining propane and butane merox (fragrance) are added to the odorless mixture in order to better detect any leaks. Furthermore, there is no difference between LPG (as a collective term for gases from liquid fuels) and LPG that is used as car fuel.

LPG is produced during the production and treatment of natural gas and petroleum and is therefore a fossil fuel. Today about 60% of LPG is extracted from gas fields against 40% from oil refining. Also when liquefying natural gas, the LPG is separated from the gas mixture because otherwise the mixture would freeze.



Bedu pumps supplies the Sero side channel impeller pumps for pumping LPG. These pumps have a very favorable NPSH value, are self-priming and can process gas bubbles up to 50%. The Sero LPG pumps are used, among other things, for loading and unloading tankers and for pumping propellant gas for filling aerosol cans.
