I'm having difficulty when trying to estimate costs using HYSYS economic analyzer.

 

For example, assume the model is just a single heater. Input, lets say water, enters at 100C and output exits at 200C at some pressure, let's say 2MPa. I can run the economic analyzer and it calculates the costs. But if I increase the outlet tempetrature to 500C, the I get the below error message.

 

"Specified utilities are unable to perform the heat transfer. Please check utility specification.

No appropriate utility available. Please check the utility specification file."

 

Also, if I choose a high temperature utility that is already in the list I can choose from, then the previous error disappears, but the following pops up:

 

"ERROR> 'HE -   15' STRESS FOR SHELL MATERIAL IS ZERO."

 

Is there a way to calculate the costs of a heater that operates at such high temperatures?
