【摘要】:以惠州石化有限公司200×10~4t/a连续重整装置为研究对象,采用英国先进技术公司KBC的流程模拟软件Petro-SIM,建立了预加氢部分、重整反应部分以及重整全流程模型,以期优化装置操作条件,改善装置的生产瓶颈。应用该模型分别对重整加权平均反应入口温度以及重整装置的3条分馏塔进行了优化分析。模拟结果得出,重整加权平均反应入口温度在520.7~521.7℃时,重整操作条件最优;预加氢产物汽提塔底温度在235℃、塔压在1.01MPa、进料温度在171℃时达到最佳的分离效果;重整脱戊烷塔塔压在1.02MPa、重整脱丁烷塔塔压在1.0MPa时塔的操作最优。通过实施优化措施,将重整加权平均反应入口温度由517.7℃提高至521℃,可增产芳烃2.7×10~4t/a,氢气1.126×10~7m~3/a;分别将汽提塔塔压、脱戊烷塔塔压以及脱丁烷塔塔压由1.1MPa降至1.0MPa,共节约燃料气3.528×10~6m~3,多回收C6环烷烃2.306×10~4t/a。核算装置效益,全年可实现节能效益197.9万元,提升装置经济效益3128.8万元。
[Abstract]:Taking the 200 脳 10 ~ 4 t / a continuous reforming unit of Huizhou Petrochemical Co. Ltd as the research object and adopting Petro-SIMM, a process simulation software of KBC, a British advanced technology company, a pre-hydrogenation part, a reforming reaction part and a whole reforming process model were established in order to optimize the operation conditions of the unit. The model was used to optimize the average reaction inlet temperature of the reforming unit and the three fractionators of the reforming unit. The simulation results showed that the weighted average reaction inlet temperature of the reforming unit was 521.7 鈩,
