The article presents criteria that should be considered in preparing a short list of acid-gas removal processes that seem to be appropriate to meet treated-gas specifications. Final selection is on the basis of technical and economic criteria. Natural gas usually contains acid gas impurities such as hydrogen sulfide and carbon dioxide. It is usually desirable to remove these impurities to prevent corrosion and freezing at low temperatures and to increase the heating value of the gas. Many processes are available for removing acid gases from natural gas, including chemical solvents, physical solvents, and membrane systems. Selecting among these processes depends on economic feasibility and cleanup ability. Oil treatment is designed to stabilize the crude oil and condensate to achieve pipeline specifications. The liquid hydrocarbon is then pumped through the nearest pipeline for export. For the development of these fields, an evacuation strategy has been performed to design central gas processing and oil treatment. The main objective of central gas processing is to provide minimum gas treatment.
