represent heat exchanger networks Pinch rules

Matching sequence, in which the design engineer starts by placing HX matches at the process pinch and works away

CP inequality, which states that for any given heat exchanger match, the CP for the stream coming out the pinch must be greater than that of the stream entering the pinch

Using these rules, a design engineer can systematically design a network that uses the minimum amount of utilities. Pinch technology software is available from Linnhoff March Inc., 107 Loudoun Street S.E., Leesburg, VA 22075.
