How to address supercritical logistics issues
Thread Content
When performing simulations in Aspen, a stream of naphtha, after passing through the heat exchanger, reaches critical temperature and pressure. Generally speaking, supercritical fluids are detrimental to heat exchangers; how can this problem be solved?
It’s difficult to determine the specific process, but it is recommended that you reduce the heat exchange area of the heat exchanger or increase the flow rate of naphtha.
Take a look at the property methods; often, there are issues with Aspen’s property methods
