Abstract: Eliminating acid gases, the most prevalent method in natural gas sweetening, is through the application of alkanolamine reactions. Numerous alkanolamine approaches every one of these have been extensively studied processes can be used to perform acid gas removal depending on the both sweet gas and sour gas parameters., Never the less one of the remaining lingering concerns is the financial implications on the process. In the present investigation, (DEA+MDEA) And mixed DGA, DEA Procedures are used to natural gas sweetening that is generated in one of the natural gas fields with significantsH2S/CO2 Ratio. A total of seven cases are created for each procedure in order to examined how the coolers operational setting affect the process performance. To ensure that lean amine hitting the absorber is a specified temperature ,the cooler function is changed for each cases .ASPEN HYSYS is used to simulate each scenario ,and ASPEN Fiscal analysis is used  to access its economic viability .According to the finding of this investigation ,as the temperature of lean-amine rises so do the appropriate solution flow rate .Nevertheless ,performing both the DGA and DEA operations at greater quantities of lean amine temperature resulted in lower process capital cost and cooling duty .In the scenario of the DEA +MDEA  the proceeding running at decrease lean amine temperature also led to reduced hydrocarbon collection.
