Abstract

Abstract:

Acetylene hydrogenation is an important device in the ethylene plant. Assume that the reaction kinetic and deactivation model are known, we optimize the acetylene convert loads between two reactors in series. The result shows that the H₂/C₂H₂ ratio of the lead reactor should be less than 1.0 and the one in guard reactor can increase from 1.9 to 3.5 according the requirement. After taking account of the operation cost and product price, we further optimize the reactor switch strategy when the acetylene convert load is optimal. In order to get a net gain of ethylene, the lead reactor should run in 14 months while the guard one should run in 4 months.

Key words: convert loads, switch strategy, acetylene hydrogenation, reactor

摘要：

乙炔加氢反应系统是乙烯生产流程中的重要装置, 在催化剂反应动力学模型和失活模型已知的情况下, 研究两组串联反应器中除炔负荷的最佳分配。通过优化计算结果显示, 一段反应器入口氢炔比尽量控制在1.0以下, 二段反应器的氢炔比根据实际需要可以从1.9逐渐提高到3.5。考虑实际的操作费用和产品价格因素, 在负荷分配优化操作的前提下, 进一步研究了反应器切换再生对整体经济效益的影响。为使其整体效益最大, 一段反应器应该使用14个月后切换再生, 而二段反应器使用4个月后就需要切换再生。
