Research on the application of advanced chemical process control will be conducted. In one project, predictive control will be applied to simple distillation towers, to towers with sidestreams, and to trains of towers. The use of variable combinations such as the separation factor instead of the product purities directly as control variables also will be tested. In a second project, short cuts on simple approximate dynamic models will be investigated. Correlations will be attempted between the tower time constants and the key process variables. These notions will be extended to include the control loop as well as the dynamics of the system.

开展先进化工过程控制应用研究。在一个项目中，预测控制将应用于简单的精馏塔、带侧流的塔和塔组。使用变量组合，如分离因子代替产品纯度直接作为控制变量，也将进行测试。在第二个项目中，将研究简单近似动态模型的捷径。将尝试在塔时间常数和关键过程变量之间建立相关性。这些概念将被扩展到包括控制回路以及系统的动力学。
