Abstract: The content of organic sulfur in natural gas of No.2 Gathering Centre Light Hydrocarbon Station of Tahe Oilfield is so high that the content of sulfur in LPG after wet desulfurization treatment is higher and fluctuates violently.In order to solve this problem,the removal efficiency of organic sulfur by UDS complex amine solution absorption method is analyzed,evaluated and optimized through solubility analysis and absorption experiments.The application results of the improved desulfurization process in the Station show that UDS solution can bring about a good effect on the removal of hydrogen sulfide and organic sulfur.Compared with the treatment by MDEA solution,the average content of hydrogen sulfide in the produced dry gas decreases from 20.3 mg/m3 to 15.1 mg/m3,and the average total sulfur content in the LPG decreases from 199 mg/m3 to 39.5 mg/m3.This technology provides technical support for the selection of organic sulfur removal process for other similar natural gas treatment stations.
