Question No: 01

For the problem given with minimum approach temperature difference, AT min

= 10 C, carry out the Energy Integration Analysis using Pinch

Technology by determining the following:

(a) Net amount of heat available in the streams based on I law.

(b) Shift of temperature scales with net heat in respective intervals.

(c) Construction of cascade diagram.

(d) Pinch temperature and minimum hot & cold utility requirement.

(e) Number of heat exchangers based on I law analysis.

(f) Number of heat exchangers based on II law analysis.

(g) Hot end design.

(h) Cold end design.

(i) Heat exchanger network for the maximum energy recovery (MER).

() Number of loops crossing the pinch.

(K) Identification of the loop (I) final heat exchanger network after breaking all the loops and restoring delta Tmin as and when there is a violation.

Assume the supply temperature of hot & cold utility are 300 C and 15 C respectively. Heat transfer coefficient of hot utility and co
