Experienced flowsheet layout personnel all emphasize the importance of breaking processes into systems and logical parts of systems such as reaction, compression, separating, finishing, refrigeration, storage, etc., for detailed drafting. This point cannot be overemphasized, since considerably more space is needed for final completion of all details than is usually visualized at first. The initial layout of the key equipment should be spread farther than looks good to the eye. In fact, it probably looks wasteful of drawing space.

Later as process and sometimes service lines, valves, controls and miscellaneous small accessories are added this “extra” space will be needed to maintain an easily readable sheet. As this develops, attention should be given to the relative weights and styles of lines to aid in the readability of the sheets.
