摘　　要：本文根据丙烯腈反应器的工艺特点,提出了反应器在DCS系统基础之上的专家控制、GPC控制技术,以及相应的控制策略;论述了装置主要质量参数反应气中的尾氧、丙烯醛含量软测量预测技术;阐述了专家控制、GPC控制、软测量原理。专家控制、GPC、软测量技术在丙烯腈反应器结合应用,取得良好效果,解决了丙烯腈装置生产瓶颈,提高了装置运行平稳率,降低了操作人员的劳动强度,提高了丙烯腈产品收率,收到了良好的经济效益和社会效益。According to the characteristics of the Acrylonitrile Unit Reactor, the expert Control technique and GPC technique are applied on DCS, and the corresponding control strategy is adopted. The soft sensor technique about oxygenic content and acroleinin content in the tail gas of reactor is discussed, the expert control theory, the GPC theory and the soft sensor theory are introduced. These techniques are successfully used in the Unit. Thereafter, the production bottleneck in the Unit is solved, the process stability is improved, the operation intensity is reduced, the acrylonitrile product yield is increased, and the economic benefit and the social benefit are obtained.
