Abstract

Gas condensates, including natural gas, industrial gases and petroleum gases, play a very important role in Iran's industry. Using these condensates as clean and renewable energy sources, in addition to reducing air pollution, saves fuel and reduces production costs. Demercaptanization unit in South Pars Gas Condensate Refinery is one of the most important refinery units that is necessary for producing high quality products and use of South Pars Gas Condensate. This process includes the removal of mercaptan from natural gas, which ultimately leads to the improvement of gas quality and increasing its economic value. Considering the importance and positive effects of improving the operating conditions in the demercaptanization unit, research in this field is very important. These investigations can identify needed improvements and provide solutions to improve unit performance. In this research, optimization of operating condition of the demercaptanization process, investigation to remove unnecessary equipment and addition of desalination part of the feed using Aspen Plus and Matlab software has been done.
