Liquefied petroleum gases (LPG) is a group of hydrocarbon gases, primarily propane, normal butane, and isobutane, derived from crude oil refining or natural gas processing. These gases may be marketed individually or mixed.

Dry gas is a natural gas or associated gas which has been treated to remove mechanical impurities, water, bupro and condensate in the gas processing plant. Its main composition is methane (CH4).

Condensate is a mixture of liquid hydrocarbons separated from associated gas fields or natural gas fields. The composition of condensate mainly consists of paraffin, including pentane and heavier hydrocarbons (C5+). Its density is about 562 to 780 kg/m3 at 15^oC (50-120 ^oAPI).

CNG (Compressed Natural Gas) is a natural gas which of main composition is methane (CH₄). It has been treated and compressed at high pressure (from 200-250 bar at ambient temperature) for advantage storage and transportation due to decrease the gas volume to 200-250 times

LNG (Liquefied Natural Gas) is a natural gas liquefied by cryogenic refrigeration at minus 162^oC after removal of impurities. LNG composition is primarily methane.
