Abstract :
Natural gas is one of the key human needs. The amount of gas impurities are, always, the most important factor and very specific in acidic conditions. Environmental issues, corrosion, reduced thermal values of natural gas, its transportation problems is dictating The amount of hydrogen sulfide and carbon dioxide gas produced to be less than 3ppm and mole %2 respectively. The most common method used to remove acid gases from aqueous solutions is the use of alkanolide amines, amines. Selective absorption technique for absorbing the hydrogen sulfide from natural gas has been used very extensively. Due to The wide use of these units, they always require further extensive work and research. The sour gas causes very strict problems to the bidboland towers in refineries. At present work an attention has been paid to the feasibility of constructing a new desalination unit at refineries, and how to achieve an economical LPG sweetening unit. To do so, an economical debate is required to assess and create more comprehensive analysis capabilities. After a thorough understanding of the problem, to obtain the optimal matching parameters of the functions of the towers, inputs and outputs, the simulation capabilities are studied and eventually the analysis results compared.
