Exercise 3 handout: Design a heat exchanger network for crude oil preheat
Q1: Started with “EX-3 Template.net”, with the following stream data, design a heat exchanger network with DTmin=10°C.
Q2: Design a network with minimum total Cost (Set the NLP optimizer option to DTmin = 1, see Appendix). This question is only for competition. The winner will receive ONE additional bonus mark.
Requirements:
(1) All exchangers’ DTs ≥ 10°C ± 0.1(Network report)
(2) All dTT =0 ± 0.1 and dDH = 0 ± 0.1 (Stream balance report)
Submission Deadline:
Report should be submitted by the Coming Thursday noon to Canvas.

Appendix:
To allow the NLP optimizer to vary DTs below 10°C, please change the Minimum Approach from 10 [C] to 1 [C] before running the optimizer.
