石油化工自动化系统发展的新趋势

The New Trend of the Petrochemical Automation System Development

石油化工自动控制系统是一个极其丰富而广泛的技术领域,根据国家《石化产业调整振兴规划》的要求,炼油和乙烯将成为石化行业的龙头和核心。针对炼油和乙烯领域探讨了当前智能控制理论及控制算法的发展概况,如人工神经网络、大系统分散智能控制、模糊控制、实时智能优化控制等理论与应用,介绍了大型石化装置的一些控制难点与解决对策。顺应国家能源政策,分析了石油化工行业的能耗状况,最后提出了许多目前行业中行之有效的节能减排的先进方法。

The automatic control system in the petrochemical industry is an extreme rich and wide range of technical field. According to the requirement of national estate adjustment programmer of the petrochemical industry, the refinery and ethylene industry will become the head and core of the petrochemical industry. Then the development situation of the present intelligent control theory and control algorithm is discussed, such as the artificial neural network, large system distributed intelligent control, blurred control, on time intelligent optimum control, etc. theories and applications. The control difficult points and the methods for solving those points in large scale petrochemical units are introduced. For the state energy source policy the energy consumption situation in petrochemical industry is analyzed. At last the effective advanced methods for saving energy and reducing waste discharge in the profession are proposed.
