Disposal Technology Research Of Natural Gas That Contains Full Carbon Dioxideof Changling Gas Field

As the world is increasing emphasis on energy saving and clean energy, of a large gasfield discovery and exploitation of the high content of carbon dioxide gas field. The presenceof carbon dioxide will lead to corrosion of equipment and piping, and carbon dioxide levelscaused by excessive heat value of natural gas below standard, can not meet the technicalindicators of the commercial natural gas requirements. natural gas decarbonizationtechnologies and natural gas processing program to deal with the high content of carbondioxide gas.This article describes the method at home and abroad deal with high content of carbondioxide gas applications, the advantages and disadvantages of membrane separation methodby comparing the activity of MDEA, Selexol method, the cold methanol method, withimproved hot potassium alkali, low-temperature separation of six commonly useddecarbonization technologyChangling gas fields of Yingcheng raw gas temperament,conditions and product gas quality requirements, as well as natural gas decarbonization ofindustrial applications, the decarburization process using activated MDEA France andmembrane separation.From the membrane separation device applications, the requirements of the aminedecarbonization device to purify the amount of gas, process plants, power consumption, theamount of circulating water, electricity, resulting in the amount of steam and the steamtreatment, fuel gas, process plants, unit energy consumption, liquid CO₂production, theenvironmental situation than eight years of the project investment cost (present value),8-yearrevenue (present value), income-costs-investment point of comparison the pure amine adecarbonization process and a membrane separation amine the advantages and disadvantagesof the method two decarburization, and ultimately determine the project decarbonization plantconstruction program to a decarburization of the pure amine. Teng of Lou library group areanalyzed, to finalize the material containing CO₂gas gas gathering pipeline and corrosioncontrol by the impact of temperature, CO₂partial pressure, flow rate, formation watercomposition of pipeline corrosion and Changling gas field approach.The high content of CO₂gas decarbonization process, for the Changling gas field and gasdecarbonization process, the practical application of certain guiding significance.
