程序系統工程學程 Process Systems Engineering 演講人: 張玨庭 民國九十年十一月十六日 成大化工系
歷史回顧(Historical Perspective) 關鍵觀念(KEY IDEAS) • 單元操作 - Unit Operations (1900 - ) • 化工科學- Chemical Engineering Science (1945 - ) • 程序系統工程 - Process Systems Engineering (1960 - )
‘Scientific Engineering’ ‘Since World War II, engineering education has moved strongly toward analysis, with courses dealing with individual process operations and phenomena. Transport Phenomena, Unit Operations, Process Control, Reaction Engineering, and other engineering science courses greatly strengthened engineering education by showing how things are and how they work. Unfortunately, there was not a parallel development of courses dealing with synthesis … This deficiency has been recognized for years, but the remedy awaited the development of sufficiently general principles of synthesis about which to organize educational material.’ (Dale F. Rudd 1973)
根據 Takamatsu (1983)在第一屆國際PSE研討會 (Kyoto,1982)所提出的定義,PSE是 "...academic and technological field related to methodologies for chemical engineering decisions concerning how to plan, design, operate and control chemical processes." Takamatsu更進一步建議將PSE列為化工的基本訓練之一,這是因為其他課程著重單元操作中的物理化學現象之瞭解,而PSE 則採取整體流程觀點,分析並設計由許多單元組成的系統。
PSE的內容 • 程序設計 (Process Design) • 程序控制 (Process Control) • 程序操作 (Process Operation)
設計『化學品製造程序』﹗ 一個創造的過程
在生產期間維持期望的程序狀態﹗ 一個追求安全與效率的工作
The way the plant is designed has a large impact on how it should be controlled and what level of control performance can be obtained. “You cannot make a garbage truck drive like a Ferrari!”
程序操作的實際工作項目 • 生產排程與規劃 (Production Planning Scheduling) • 線上最佳化 (On-Line Optimization) • 失誤偵測與診斷 (Fault Detection and Diagnosis) • 危害評估 (Hazard Assessment)
與PSE相關的必修及必選課程 • 計算機概論 (一上) • 質能均衡 (一下 ) • 工程數學(二上、下 ) • 程序控制(三上)及實驗(三下) • 程序設計(四上) • 工業安全與衛生(四下) • 其他﹕單元操作、化工熱力學、化工動力學
與PSE相關的選修課程 • 數值方法 • 製程最適化 • 電腦程序控制 • 製程安全技術 • 清潔製程 • 物件導向程式設計
工具軟體 • C/C++/FORTRAN 計算機概論 • ChemCAD 質能均衡、程序設計、單元操作 • Matlab 工程數學、程序控制

PSE領域之擴展 • Process Systems Engineering is concerned with the improvement of decision-making processes for the creation and operation of the chemical supply chain. • It deals with the discovery, design, manufacture and distribution of chemical products in the context of many conflicting goals. Grossmann and Westerberg (2000)
Process and Product Design • Molecular design • Process intensification • Design of sustainable and environmentally benign processes • Synthesis of microchips and bioprocess systems • Design and analysis of metabolic networks
Process Control • Integration between design and control • Applications in bioprocesses and biomedical devices • Plant-wide control • Hybrid systems • Sensors
Process Operation • Optimal planning and scheduling for new products • Supply chain optimization • Real-time scheduling and inventory control • Synthesis of operation procedure • Process verification
