·         General information

·         Heuristics

For pressure drops, approach temperatures, utilities, refrigerants, etc.

·         Access Engineering (McGraw-Hill books, available free for AIChE members through their site)

·         Heat Transfer in Process Engineering

·         Perry's Chemical Engineers’ Handbook, 8th edition

·         Marks’ Standard Handbook for Mechanical Engineers, 11th Edition

·         Handbook of Chemical Engineering Calculations, 3rd Edition

·         Working Guide to Process Equipment, 3rd Edition

·         Typical heat transfer coefficients

WARNING:  The values of U originating from Walas are extremely misleading and confusing.  They should not be used.  (That is, the heuristics posted here, those in Turton et al., and those from AIChE.)  Use instead one of the following sources:

·         Heat transfer fluids

·         Simulation using HYSYS or UniSim
It is a very serious error to show a pressure increase for a stream going through a heat exchanger

·         Heat exchanger design using UniSim
If UniSim’s Heat Exchangers is also installed along with UniSim Design, then heat exchanger details can be calculated rather than estimated.  The following methods are available:
