化工行业属于国家的基础产业和支柱产业，是国民经济的重要组成部分。化工行业具有易燃易爆、有毒有害、腐蚀等危险性特点，化工生产过程常常伴随高温、高压及低温、负压等复杂工况。物料危险性大、工艺条件复杂、工艺过程控制难度高是化工生产的明显特征。化工过程的自动化控制是减少化工生产过程风险的有效措施。本文将对化工安全生产中自动化控制技术的应用展开论述“,”Chemical industry belongs to the basic industry and pillar industry of the country, is an important part of the national economy. Chemical industry is flammable and explosive, toxic and harmful, corrosion and other dangerous characteristics, chemical production process is often accompanied by high temperature, high pressure and low temperature, negative pressure and other complex conditions. The obvious characteristics of chemical production are high material risk, complex process conditions and difficult process control. Automatic control of chemical process is an effective measure to reduce the risk of chemical production process. This paper will discuss the application of automatic control technology in chemical safety production.
