1 前言乙烯氧氯化反应单元是一个易燃、易爆、易腐蚀的单元。我厂氯乙烯装置现有两套氧氯化单元,一套老的是引进日本三井东压公司的70年代的技术,一套新的是引进德国Hoecst公司90年代技术,两者技术各有其特点。本文试就两者的稳定安全性作初步的分析。2 氧氯化单元稳定安全性比较 (1)反应器结构与反应工艺及安全性新老氧氯化反应器均为流化床反应器,反应温度控制均要求小于240℃,反应的热量移去均通过反应器里的蛇管中冷却水的汽化而吸热进行的,反应器顶
1 Introduction Ethylene oxychlorination reaction unit is a flammable, explosive, corrosion-prone unit. Chlor-ethylene plant in our plant has two sets of oxychlorination unit, an old one is the introduction of the Japanese company Mitsui East pressure of the 70’s technology, a new set is the introduction of the German company Hoecst 90’s technology, the two have their own technology Features. This paper tries to make a preliminary analysis of the stability and security of the two. 2 Comparison of stability and safety of oxychlorination unit (1) Reactor structure and reaction process and safety Both the old and the new oxychlorination reactors are fluidized bed reactors. The reaction temperature control requires less than 240 ° C, and the heat of reaction is removed Are through the reactor tube cooling water vaporization and endothermic, the reactor top
