In HYSYS simulation of natural gas dehydration, when using the PR property package and the Glycol property package, the calculated results for heat exchanger duty and water dew point show a large discrepancy. What causes this error, and which property package should be selected in the calculation

Hi.

a search using Google AI:

Natural gas dehydration with a glycol properties package involves using a glycol solution, typically triethylene glycol (TEG), to absorb water from a natural gas stream. The process relies on the physical properties of glycol, such as its high boiling point and hygroscopic nature, to remove water vapor. The "glycol properties package" in simulations helps model this process by using specific thermodynamic models like the TST (Twu-Sim-Tassone) equation of state to accurately predict the phase behavior of the glycol-water mixture.
