Disregard question number 1, make a hot and cold composite curve + combine hot and cold composite curve + energy cascade analysis and determine q_net, q_c, and q_h

PROBLEM NO. 1 Given the following streams: 1. Design a heat exchanger network so that all the streams achieve their target temperatures. The temperature difference (TMIN) for all exchangers >/10K. Suitable hot and cold utilities are available. Try to minimize the use of utilities and also try to avoid networks having many exchangers. 2. For this problem, the target utility requirements (which can be calculated by the 'Problem Table' procedure given on pp.25-28of the I.Chem.E. Guide) are Qh=170kW and Qc=50kW. Thus, starting at the cold end and using these targets, design a network which satisfies these targets and has six heat exchangers (including heaters and coolers)
