How to select moist air in Aspen? !
Thread Content
Define the water component, and then for the gaseous state? !
Just enter it based on its actual composition; at a constant temperature and pressure, water in the air should be in gaseous form, so it is naturally gaseous, and there’s no need to set it manually
I understand that the saturated humidity at a certain temperature is constant. But I need to check what the moisture content in the air is at this temperature, and then enter that value? ! Is there no component that can be selected directly?
Please take another look at this post for me: https://bbs.hcbbs.com/thread-2023387-1-1.html
There is a humidity module in HYSYS; I still don’t know how to set it up in A+
Yes, indeed. It may need to be defined by oneself.
Wet air is defined by you; of course, you need to know the humidity in advance
It’s not you who has to do the calculations; you just input a certain amount of air and an excess amount of water, and use the Flash2 module to automatically calculate the gas-liquid equilibrium – that is, to determine how much water is contained in the air
Won’t that excess water be carried into the subsequent processes? !
