I want to design/simulate an adsorber in Aspen Plus. As adsorber is not a part of the Aspen Plus, it needs to be exported from Aspen Custom Modeler. Can anyone help me in coding in Aspen Custom Modeler for design of Adsorber and export to the Aspen Plus? Thanks.
Simply use the RADFRAC block to model an absorber. In Specifications-Setup: Set the Condenser and the Reboiler to "none" and add the liquid on stage1 and the gas on the last stage.
Be sure to use correct vle-models and parameters! It´s crucial! Calculation type Rate-Based is recommended anyway. If convergence is hard, set Convergence to custom and supply estimates for the composition and temperature profiles.
Dear Markus H Bauer , Sir, I am asking about Adsorber, not Absorber :-)
What type of Adsorber and how much detail do you need? A H2 Pressure swing adsorption adsorber can be modelled as a simple component separator that has the correct product recovery and purity or it could have some more sophisticated calcs for cycle time adsorption, desorption and pressure equalization steps
Dear Sir Rick Manner , I want to design an adsorber to dry air..

You can use the tutorial of Aspen Costum Modeler that existed in Aspen site and databankes. You can always use the Fortran codes in Aspen Costum Modeler.
Good luck
