Gas condensate (sometimes referred to as condensate) is a mixture of low-boiling hydrocarbon liquids obtained by condensation of the vapors of these hydrocarbon constituents either in the well or as the gas stream emits from the well. Gas condensate is predominately pentane (C5H12) with varying amounts of higher-boiling hydrocarbon derivatives (up to C8H18) but relatively little methane or ethane; propane (C3H8), butane (C4H10) may be present in condensate by dissolution in the liquids. Depending upon the source of the condensate, benzene (C6H6), toluene (C6H5CH3), xylene isomers (CH3C6H4CH3), and ethyl benzene (C6H5C2H5) may also be present. Additionally, gas condensate has trace amount of hydrogen sulfide (H2S), carbon dioxide (CO2), mercaptans (RSH, R= -CH3, -C2H5) and aromatics.
Generally, gas condensate contains more than 50% motor spirit (regular octane/petrol) in the boiling range of 21-145 , 23% kerosene in the boiling range of 140-221 and 24-25% diesel in the boiling range of 178-335 . Remaining 2-3% is found as residue and system loss.
