Recently, due to the very good market in ethane as a feedstock for petrochemical complexes, there are some plans to make a deep ethane recovery from the gases produced in Iran southern fields. In this work, the feasibility of different technologies for deep ethane recovery from a specified feed gas produced in one of the Iran southern fields is reviewed. Three different processes are selected and simulated for the specified feed gas. These processes are compared from technical and economic viewpoints and the advantages and disadvantages are discussed. The results show that RSV and CRR processes are technically more feasible for high levels of ethane recovery (greater than 95%). The economic evaluations show that the CRR process is the most appropriate one for the feed gas specified in this study.
