Process Operability

An integration of process design and operations

 

The material in this section provides teaching and learning materials for undergraduate education in process operability.  For the purposes of this presentation, operability is defined concisely in the following.

 

Operability encompasses characteristics that ensure the process has the capacity and flexibility to achieve a range of operating conditions safely, reliably, profitably and with good dynamic performance and product quality.

Operability must be considered at the design stage to ensure excellent dynamic operation can be achieved.  Therefore, the topic links the process control and process design courses, and the materials here are appropriate for either or both courses.

None of the content in operability is entirely new.  However, the integration of these many process systems engineering topics is novel.  They can be easily included in a process design course, with operability a natural topic after flowsheeting and before/integrated with equipment sizing and economic analysis.

 

In addition, the teaching and learning materials presented here are available at no cost to the student and to academic departments at not-for-profit academic institutions.

To introduce the operability concepts and present the compelling reasons for including operability in the undergraduate curriculum, a white paper and accompanying conference presentation are available.  If you are interested, they may be downloaded by clicking on the following icons.
