摘要
中原油田石油化工总厂催化裂化装置脱硫系统的乙醇胺再生塔在运行过程中经常出现冲塔现象，不仅使乙醇胺损耗增加，也严重影响干气和液化气的产品质量。通过分析并查找原因，对主要参数进行优化调整，将再生塔塔底的汽返温度控制在115～120℃，液化气重组分体积分数控制在1．5％以下，干气重组分体积分数控制在2％以下，富液闪蒸罐压力控制在0．30MPa左右，乙醇胺过滤量调整到3t／h，经过调整，平稳了脱硫系统的操作，保证了干气和液化气的产品质量，减少了乙醇胺的损耗。
The reasons for operation fluctuation in the ethanol amine solvent regeneretion tower of the sour gas desulphurization system were analyzed. The flood phenomena increased the loss of dietha- nol amine and affected the quality of dry gas and liquefied gas. Based on the analysis, the following operation parameters were required to solve flood problem： the steam temperature from the bottom of the regeneration tower was controlled at 115--120 ~C, the volume fraction of the heavier component in liquefied gas and the dry gas were reduced to less than 1.50/oo and 2%, respectively, the pressure of flash tank of rich diethanol amine solution was set at 0.30 MPa, the load of filtered diethanol amine was ad- justed to 3 t/h. These measures make the operation stable, and assure the qualities o{ dry gas and LPG products. The loss of diethanol amine is reduced and the economic benefits of enterprises are increased.
