Problem 15.22 below for reference:

have the following film heat transfer coefficients, estimate the optimum minimum approach

23. If the streams in Problem 15.22 have the following film heat transfer coefficients, estimate the optimum minimum approach temperature for this problem. = OL = h = 75 BTU/hr/ft2F h = 25 BTU/hr/ft?F h3 = 10 BTU/hr/ft2F ha=45 BTU/hr/ft?OF h = 30 BTU/hr/ft2F ho = 30 BTU/hr/ft2F = = = 55/ Six streams in a chemical process need to be heated or cooled. The thermal data for these streams are given in the following table: Stream No. C, (109BTU/hrF) Tin (F) Tout (F) 1 1.0 620 320 GOD 2 6.0 420 120 3 3.0 420 220 4 5.0 400 600 5 2.0 200 300 6 4.0 100 400 a. Calculate the minimum hot and cold utility loads for this process subject to a minimum approach temperature of 20F. b. Calculate the pinch temperatures for this process. You may assume that there is only one hot and one cold utility available. C. Calculate the minimum number of exchangers needed for the minimum energy case for above and below the pinch. d. Design the MUMNE network for the process. 23. If the sto
