摘要：以具有工业应用背景的XDS为溶剂进行了1.5 MPa压力下脱除模拟川东北高酸性天然气中有机硫等有害组分的研究,与MDEA溶剂的净化效果进行了对比,并对XDS溶剂脱除有机硫的机理进行了分析。在操作压力1.5 MPa、温度40℃、气液体积比为126的条件下,MDEA溶剂吸收的净化气总硫含量符合二类气指标,而XDS溶剂的净化气H2S含量小于0.5 mg/m3、总硫含量小于20 mg/m3,达到一类气指标,表明XDS溶剂对天然气中有机硫的脱除效果明显优于MDEA溶剂。
Using XDS solvent to remove organic sulfur containing compounds from high sour natural gas was investigated. Meanwhile,a comparison of the sulfur removal performance of XDS solvent and MDEA solvent was carried out and the sulfur removal mechanism of XDS solvent was discussed. Results showed that under the conditions of an operation pressure of 1.5 MPa,an absorption temperature of 40 ℃ and a gas to liquid volume ratio of 126, the total sulfur content of the purified gas treated by MDEA solvent met the requirements of second class gas;the purified gas treated by XDS solvent having a H2S content of less than 0.5 mg/m^3 and a total sulfur content of less than 20 mg/m^3 well met the requirements of first class gas, which indicated that treating high sour natural gas the sulfur removal performance of XDS solvent was better than that of MDEA solvent.
