Issues related to conducting sensitivity analysis in case studies

Thread Content

When first starting to learn ProⅡ, the questions might be quite simple. I’m using a case study to determine the curve of the vapor phase fraction at the outlet of the flash module as a function of the flash temperature. The parameters have been entered correctly, but in the results I cannot find the gasification fraction for the flash module – only the gasification fraction of the stream. Could any experienced colleagues provide some guidance? Thank you!

The vapor fraction at the top outlet of the flash tank is 1, while the vapor fraction at the bottom outlet is 0. Which exit do you say can be for the gas-liquid two-phase flow?

A calculator can be used to compute the ratio of the flash gas phase (by mass or moles) to the feed, ensuring that the units are consistent. Parameter: temperature parameter of flash. Result: value of the calculator.

I described it incorrectly; it’s the vaporization fraction in the flashing process

Then use a valve; by defining the outlet pressure, the gas phase fraction can be seen.
