Ethylene production by oxidative pyrolysis of natural gas is based on a complex chemical engineering process. One of the main stages of this process is hydrogenation of acetylene in the ethane-ethylene fraction using catalysts that increase the efficiency of the process. Acetylene hydrogenation produces byproducts that cause coking of the catalysts and thereby reduce their activity. This article presents a catalyst coking prevention system based on use of an advanced control system (ACS) and a genetic algorithm. The proposed control system can be used to switch from planned catalyst regeneration to its regeneration based on the actual state of coking.

乙烷-乙烯馏分中的焦化控制系统乙炔加氢催化剂

通过天然气的氧化热解生产乙烯是基于复杂的化学工程过程。该工艺的主要阶段之一是使用提高工艺效率的催化剂对乙烷-乙烯馏分中的乙炔进行加氢。乙炔加氢产生的副产物会导致催化剂结焦，从而降低其活性。本文介绍了一种基于先进控制系统 (ACS) 和遗传算法的催化剂结焦预防系统。所提出的控制系统可用于根据焦化的实际状态从计划的催化剂再生切换到其再生。
