Chapter 11
An Overview:Design of Simple and Robust Process Plants

11.1
Design Philosophies

An overview is prepared of what the design of simple and robust process plants
includes. It summarizes the key elements, starting with a definition of a simple and
robust process plant and followed by the 10 design philosophies. The list is contin-
uous with the key elements in sequential order of the chapters. A simple and robust
process plant can be defined as:

An optimal designed safe and reliable plant, operated hands-off at the most economical
conditions.

11.2
Ten Design Philosophies to Achieve a Simple and Robust Process Plant

The ten design philosophies are as follows:
1. Minimize equipment, piping and instruments. The keywords for simplifica-
tion and minimization of functions are: Avoid/Eliminate, Substitute, Com-
bine/Integrate, Added value?
2. Design for single reliable and robust components, unless justified economic-
ally or safety wise.
3. Optimize design.
4. Clever process integration.
5. Minimize human intervention.
6. Operation optimization makes money.
7. Just-in-time production (JIP). With key elements: avoid or minimize logistic
facilities.
8. Total quality control (TQC). With the key elements: prevent versus cure and
first-pass prime production.
9. Inherently safer design. With the key elements: Minimize, Substitute, Mod-
erate, Simplify.
10. Environmentally sound.
