专用化学品联合装置的分布式协同调控与智能集成优化

Specialty chemicals industry is an important component of the economy of Zhejiang Province. Many products have become the largest volume ones in the world. However, the plants also face the difficulties and challenges for the low competitiveness and high pressure in safety, pollution, and energy cost. In this project, how the advanced automation techniques can be well applied into the specialty chemicals production is studied. By analyzing the features of the process, the project is planned to develop theory and methods by investigating different layers of the automation, including advanced control, operational optimization, production scheduling, process integration, and online monitoring. The detailed contents include the following issues. To deal with the control of the long flowsheet with a large number of units including both continuous and batch operations, a distributed cooperative control strategy will be developed. To optimize the profit, an integration of the production scheduling and dynamic optimization for process transition will be studied. To reduce the energy and waste, the synchronized design of the heat and mass exchanger networks will be synthesized. To meet the requirement of safety and environment, online monitoring and diagnosis of the safety and environmental indexes will be developed. Finally, the proposed methods will be demonstrated on a chemical intermediate plant.
