Hello

I want to simulate deaerator in hysys,but there is no heat exchanger like deaerator in hysys, can any one help me to simulate it? thanks

or can anyone help me in data extraction from deaerator due to heat integeration problem..

in my deaerator 4 stream enter it and only 1 stream exit from it...

A deaerator is for removing dissolved gases like oxygen.

A simple shortcut distillation module should suffice.

I have 4 stream that enter the deaerator and 1 stream that leave it.... but shortcut column accept only one steram...how can I simulate it??

There is no problem to introduce 4 streams into a vessel and to specify the outlet stream at saturated conditions (Deareator Function) in Hysys.  The tough part of a deaerator simulation is its converging process because more steam needs more BFW and more BFW needs more steam for deareation.

The MIX unit module.

i think you should simulate it by according of packing column or tray column,  not heat  exchanger..
