延迟焦化装置吸收稳定系统流程模拟与优化

Process Simulation and Optimization of Absorption Stabilization System in Delayed Coking Unit

本文采用PROII模拟软件,以某炼厂延迟焦化装置吸收稳定系统为基础,考察补充吸收剂流量、增加吸收塔塔顶冷却器及分液罐对吸收稳定系统的影响,结果表明增加补充吸收剂流量和增加吸收塔塔顶冷却器及分液罐,在保证液化石油气及稳定汽油等产品质量控制不变的条件下,可有效降低干气中C3及以上组分的含量,给装置带来一定的经济效益。这些定量化的分析结果对如何调节干气不干问题具有一定的指导意义。

Based on absorption stabilization system of delayed coking unit in a refinery,this paper uses PROII simulation software to investigate the effects of supplementing absorbent flow,adding cooler at the top of absorption tower and liquid separation tank on absorption stabilization system.The results show that the content of C3 and above components in dry gas can be effectively reduced and certain economic benefits can be brought to the unit by increasing the flow rate of supplementary absorbent and increasing the cooler and liquid separation tank at the top of absorption tower under the condition of ensuring the quality control of liquefied petroleum gas and stable gasoline.These quantitative analysis results have certain guiding significance on how to adjust the dry gas drying problem.
