High Pressure Ammonia Absorber Simulation
High Pressure Ammonia Absorber Simulation
(OP)
Hello All,
I want to simulate An ammonia absorber same as the attached sketch.The purpose of the simulation is to see the effect of increasing ammonia concentration in the solvent stream on the top product stream ammonia concentration. Could you please advise me what fluid package I should use in oreder to get more reliable results??

The other problem you've got is to convert the 20 real trays to equilibrium trays or theoretical trays - there are examples for this translation in the Gas Absorption chapters in Perry Chem Engg Handbook.

Solving separations I set the same model for both VLE and Enthalpy (for example, Peng-Robinson + NRTL with Huron Vidal mixing rules, PRX-NHV in Prode) , but I don't know if that is possible with your software.

Well I will be using aspen hysys software for the simulation.
