针对塔二联轻烃站脱硫装置天然气中 H2 S含量变化较大,脱硫不达标的实际情况,对脱硫装置的运行参数进行敏感性分析。分析结果表明,吸收塔操作压力、操作温度及M DEA 循环量对净化气中 H2 S含量影响不大,而再生塔操作参数对脱硫效果的影响非常显著。因此,只对M DEA再生塔操作参数进行调整。结果表明,在塔二联天然气中H2 S质量分数增加58%的条件下,对M DEA再生塔操作压力和温度进行微调,可有效降低净化气中 H2 S含量并使其达标。
針對塔二聯輕烴站脫硫裝置天然氣中 H2 S含量變化較大,脫硫不達標的實際情況,對脫硫裝置的運行參數進行敏感性分析。分析結果錶明,吸收塔操作壓力、操作溫度及M DEA 循環量對淨化氣中 H2 S含量影響不大,而再生塔操作參數對脫硫效果的影響非常顯著。因此,隻對M DEA再生塔操作參數進行調整。結果錶明,在塔二聯天然氣中H2 S質量分數增加58%的條件下,對M DEA再生塔操作壓力和溫度進行微調,可有效降低淨化氣中 H2 S含量併使其達標。

Aiming at the fluctuation of H 2 S content in natural gas and the unqualified natural gas , the sensitivity analysis of operating parameters that affect the desulfurization device were made .The analysis result indicates that operating pressure ,temperature of the absorber and MDEA circulation flow rate have little effect on H2 S content in sweet gas ,but operating parameters of regenerator have a great influence on desulfurization effect .Therefore ,only operating parameters of MDEA regenera‐tor were adjusted .The results show that when the mass fraction of H2S in natural gas increased by 58% ,it can effectively reduce the content of H2 S in the sweet gas to reach the standard by slightly ad‐justing operating pressure and temperature of MDEA regenerator .
