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.

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

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

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

It is the simplest form of presentation.

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

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.
