茂名石化公司炼油厂第一套常减压蒸馏装置采用改进的Ｓｍｉｔｈ预估器，实现了常压炉和减压炉支路平衡控制；采用抑制波动的广义预测控制理论，实现了蒸馏塔顶、常压二线、常压三线馏出口温度和初馏塔侧线温度控制；采用化学模式识别理论的多重判别矢量方法，实现了常压塔和减压塔的在线优化。有效地稳定了生产，提高了产品收率，经济效益显著。软件投用半年，已获经济效益５６９万元。该项目首次在国内实现了化学模式识别方法在过程控制在线优化中的应用，经中国石化总公司组织的技术鉴定，属国内首创，具有国内先进水平。
Maoming Petrochemical Company Refinery first set of atmospheric and vacuum distillation unit using an improved Smith predictor to achieve atmospheric pressure furnace and vacuum manifold branch balance control; using generalized predictive control theory to suppress fluctuations to achieve the distillation overhead, Atmospheric pressure second-line, atmospheric pressure three-stage distillation outlet temperature and the temperature of the stripper side line control; using the chemical pattern recognition theory of multiple discriminant vector method to achieve the atmospheric and vacuum tower on-line optimization. Effectively stabilize the production, improve product yield, significant economic benefits. Software investment for six months, has received 5.69 million yuan of economic benefits. The project for the first time in the country to achieve a chemical pattern recognition method in online optimization of process control applications by the China Petrochemical Corporation technical appraisal, is a domestic initiative, with the domestic advanced level.
