CO2 capture process study using gPROMS and Aspen Properties

Researchers in the Department of Chemical Engineering at National Tsing Hua University have developed models of a packed bed and of a rotating packed bed in gPROMS in order to make a comparison of the two technologies for CO2 capture by monoethanolamine and dilute aqueous ammonia solutions. They have linked their gPROMS models with Aspen Properties through CAPE-OPEN in order to access an electrolyte-NTRL thermodynamic model provided by Aspen Properties and fitting their needs in terms of accuracy. These researchers have reported today their work in a paper published in the International Journal of Greenhouse Gas Control.

Use of the CAPE-OPEN thermodynamic socket in gPROMS to perform calculations provided by a CAPE-OPEN Property Package, here one exported from Aspen Properties, is a proof of the interoperability that can be achieved through the CAPE-OPEN technology.
