Design Process

• Formulating Problem

• Formulating Alternatives

• Generating Alternatives

• Analyzing Alternatives

• Evaluating Alternatives

It shows all major as well as minor equipment more realistically than on the process flowsheet. Included are sizes and specification classes of all pipe lines, all valves, and all instruments.

• Block Flow Diagram

• Process Flow Diagram

• Piping and Instrumentation Diagram

Formulating Problems...

• Establish functional requirements

• Determine parameters

• Determine constraints

• Set performance targets

P&ID's of a particular unit such as compressor, and inlet filter scrubber.

(a)  

Generating Alternatives: create alternative forms ( (a)   , materials, processes)

Evaluating Alternatives: best alternative design candidate (_____ _____, optimum design)

(a)  

P&ID's of utilities such as instrument air and oil system, oily water and wastewater, and tempered water.

(a)  

It is the simplest form of presentation.

(a)  

The blocks do not describe how a given step will be achieved, but rather (a)  

P&ID's of header distribution systems shown geographically. It should be noted that the system need not necessarily be limited to utility distribution and can be used for process distribution.
