Study on the causes and solutions of liquid flooding in desulfurization process of oilfield associated gas
The reasons for the liquid flooding in the associated gas desulfurization process were analyzed from two aspects of the main pollutants in the amine solution and the mass transfer mechanism of the traditional tray,and the technical route to solve the problem was determined.The work principle of CJST and the advantages used in associated gas desulfur-ization process were introduced.The structure of CJST was optimized with CFD simulation technology and the CJST was realized industrial application in the associated gas desulfur-ization process.Industrial application results proved that the liquid flooding was effectively solved and the absorption efficiency was significantly improved,and the energy consumption of amine liquid regeneration was reduced by about 20%.
