.Introduction The gas is present in two types according to its discovered in the wells ,so it could be called natural or associated gas. The gas which  present in wells separately is called natural gas and it is basically light gas in its composition contaminated with some impurities which should be removed before using it as fuel, while the gas which present in oil wells is called associated gas and its component is commonly heavy rich with worthy product which could be obtained in industrial  base as in LNG and NGL plants. The gas is commonly hydrocarbon gas phase components basically consists of methane , ethane , propane , butane , pentane and heavier in addition to some impurities such as .soured gas ( CO, !" # , $ercury , !O and wa%es &or going on and as common definition we will use the common 'abbreviations for the basic components of gas as follow formula abbrev C! C) C!+ C C-!) CC!)1 C C!)1 C 2!3 C2 2!3 C2 2!3 C2 //// C1

The main upstream process e%ecuted to the gas aim to prepare the gas to be used as final fuel source if it is a natural gas or to be delivered to the down stream plants for further process to obtain high economic .value products and residue gas which will be used as final source fuel
