LPG Sample Cylinders
Specification of the hydrocarbon composition of LPG is required as traces of hydrocarbon impurities in LPG can negatively effect the fuel quality and processing. The compound distribution data of the hydrocarbons can also be used to calculate properties including relative density, vapor pressure, and motor octane number. This application note describes the gas chromatographic analysis of the hydrocarbon composition of LPG using the BRT Liquefied Gas Injector (LGI).

One of the specifications of commercial LPG is the amount of oily residue. Oily residue leads to troublesome deposits that will accumulate and corrode or plug the LPG fuel filter, the pressure regulators, the fuel mixer or the control solenoids. Currently ASTM D2158 or ISO 13757 are used. These methods main disadvantage is that large amounts of LPG need to be evaporated which is a safety risk. The preferred alternative technique is gas chromatography.
