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)
什麼是
『程序系統工程』﹖
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)
什麼是程序設計﹖

什麼是程序控制﹖
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
Home Heating Control System
Preheater/Reactor Process  Cascade Control
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!”
什麼是程序操作﹖
支援生產的活動！
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)

未來展望
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
