Study on Desulfurization and Decarbonization Technology of Natural Gas on Bohai Offshore Platform
Abstract Based on the latest developments of desulfurization and decarbonization technologies of acidic natural gas, the process characteristics, product purity, consumptions, occupied area, advantages and disadvantages of various desulfurization and decarbonization methods are analyzed and compared, and the adaptability of the methods on offshore platform is fully considered. According to the actual situation of a Bohai offshore gas field, the low temperature separation method is adopted and the desulfurization and decarbonization process is simulated by using HYSYS software, and then the technical scheme is put forward to meet the requirements of the gas turbines on surrounding platforms and the transportation quality index of the southwest Bohai gas supply pipeline network. This research has a certain reference value for technical programs of natural gas desulfurization and decarbonization on similar offshore projects.
