1. The temperature interval diagram for a process is shown below. For this process, do the following: Stream 1 2 3 4 st 5 en 6 HCFR (kW/C) 1.0 ? 3.0 5.0 ? 4.0 ZHCFR AT (kW) 600 (C) 580 (C) 400 500 (C) 480 (C) B ? 3 400 (C) 380 (C) 4 -600 300 (C) 280 (C) D 300 200 (C) 180 (C) 5 E ? 100 (C) 80 (C) 6 a. Compute the missing values of HCFR for Streams 2 and 5 and the missing Q values for temperature intervals B and E. b. Calculate the minimum hot and cold utility loads for this process subject to a minimum approach temperature 20 (-C). c. Calculate the pinch temperatures for this process. Assume that there is only one hot and one cold utility available. d. Calculate the minimum number of exchangers needed for the minimum energy case, for above and below the pinch. e. Draw the heat exchanger network for the process. f. Calculate the % savings for hot and cold utilities
