| 针对塔二联轻烃站脱硫装置天然气中H2S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MDEA循环量对净化气中H2S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MDEA再生塔操作参数进行调整。结果 表明,在塔二联天然气中H2S质量分数增加58%的条件下,对MDEA再生塔操作压力和温度进行微调,可有效降低净化气中H2S含量并使其达标。 |

| Abstract: |
| Aiming at the fluctuation of H2S 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 H2S content in sweet gas, but operating parameters of regenerator have a great influence on desulfurization effect. Therefore, only operating parameters of MDEA regenerator 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 H2S in the sweet gas to reach the standard by slightly adjusting operating pressure and temperature of MDEA regenerator. |
