【摘要】：催化裂化干气制乙苯第三代技术是由中科院大连物化所、抚顺石化分公司和中国寰球工程公司辽宁分公司共同开发的。第三代技术采用气相烃化反应与液相反烃化反应,分别在两个反应器内进行,器内填充分子筛催化剂,该技术路线在干气制乙苯方面具有独特优势。本文对催化裂化干气制乙苯的一至五代技术做出了一定的介绍与对比。针对第三代干气制乙苯技术使用流程模拟软件PRO/II进行了全装置的流程模拟计算与动力模型分析,并在此基础上对流程的分离指标和能耗进行了优化与对比。PRO/II流程模拟所采用的数据为某化工厂的实际运行数据,选用软件内部嵌套的Soave-Redich-Kwong物性方程,该方法能够准确的计算汽液平衡与物料性质,通过选定适当的撕裂物流、收敛方法及设备计算顺序能使流程快速收敛。将全装置流程模拟数据与实际数据进行对比,结果较为吻合。
[Abstract]:The third generation technology for producing ethylbenzene from FCC dry gas was developed by Dalian Institute of Physicochemistry of Chinese Academy of Sciences, Fushun Petrochemical Branch and Liaoning Branch of China Global Engineering Company. The third generation technology adopts the gas phase reaction and the liquid opposite hydrocarbon reaction, carries on in two reactors separately, fills the molecular sieve catalyst in the reactor, this technical route has the unique superiority in the dry gas to produce the ethylbenzene. The first to fifth generation technology of producing ethylbenzene from FCC dry gas is introduced and compared in this paper. The process simulation calculation and dynamic model analysis of the third generation dry gas ethylbenzene production process were carried out by using the process simulation software PRO/II. On this basis, the separation index and energy consumption of the process are optimized and compared. The data used in the process simulation are the actual operation data of a chemical plant, and the Soave-Redich-Kwong physical property equation nested within the software is selected. This method can accurately calculate the vapor-liquid equilibrium and material properties. By selecting appropriate tearing logistics, the convergence method and the equipment calculation sequence can make the process converge quickly. The simulation data are compared with the actual data, and the results are in good agreement.
