Determination of the Density of Liquefied Petroleum Gas

Liquefied petroleum gas (LPG) is a by-product in petroleum refining and in natural gas processing. The density of LPG is an important quality indicator and can be determined effortlessly and accurately with DMA™ 4200 M.


Liquefied petroleum gas (LPG) mainly consists of propane, butane, and mixtures thereof. These gases are by-products in petroleum refining and in natural gas processing.

At room temperature and barometric pressure, these substances are gases, but under pressure and/or low temperature they can easily be liquefied.

LPGs are used as fuels in industry, houses and cars, as well as starting materials in chemical industry, propellant gases in aerosol bottles, refrigerants in cooling systems, etc.

The density of these liquids is an important feature for quality control in processing and transporting these substances.
