Let’s do some hysys optimization questions
Thread Content
The model is in the attachment. What I asked for was different from the results in the book. The optimization problem uses water with an initial temperature of t1=20 degrees to cool a certain process fluid from 80 degrees to 30 degrees, and the heat transfer is 100 kilowatts. A counterflow heat exchanger is required to minimize total cost. known: Total investment cost f = 1.3 * 0.65 * 276 * Heat exchange area raised to the 0.8th power * 0.2+water volume * 0.0004 * 8000 (annual start-up time). beg : Friends who are interested in the heat exchange area and water flow rate at the optimal time should take a look.
