The flowsheet is the “road-map” of a process, and serves to identify and focus the scope of the process for all interested and associated functions of the project. As a project progresses, the various engineering disciplines read their portions of responsibility from the flowsheet, although they may not understand the process or other details relative to some of the other phases of engineering. Here is where the process and/or project engineer serves to tie together these necessary segments of work. This often involves explanations sufficiently clear to enable these other groups to obtain a good picture of the objective and the problems associated with attaining it.

The flowsheet also describes the process to management as well as those concerned with preparing economic studies for process evaluation.

A good process flowsheet pictorially and graphically identifies the chemical process steps in proper sequence. It is done in such a manner and with sufficient detail to present to others a proper mechanical interpretation of the chemical requirements.

There are several types of flowsheets:
