烷基化反应系统控制方案的探讨

Discussion about Control Scheme for the Alkylation Reaction System

以苯乙烯装置中乙苯单元烷基化反应系统为例,简述了烷基化反应系统工艺流程,描述了乙苯的制取方法、生产过程以及主要流程。详细分析了乙烯压缩机防喘振控制、进料温度串级控制等控制方案。通过论述苯乙烯合成前期中乙苯单元烷基化反应的主要控制方案,探讨了复杂控制算法在烷基化反应控制系统中的应用。

To take the alkylation reaction system in the styrene unit as an example, the process of the alkylation reaction system is presented, the ethylbenzene production and main flowsheet is described, the ethylene compressor anti-surge control, cascade control of feed temperature is analyzed in detail. Through the discussion of the main control scheme of the alkylation reaction, the application of complex control algorithms is investigated.
