chemical process engineering
The chemical process engineering has shell & tube heat exchangers. Which has TEMA types. There have 2 types heavy duty heat exchangers and lighter duty heat exchangers. In heat exchanger chemical industry they typically uses heavy duty heat exchangers (TEMA ‘R’). Each TEMA has main parts like channel, the tube bundle, the rear head and the shell. The heat exchanger deign handbook has all the details about TEMA types, comparisons & usage applications of each type.
