Heat transfer intensification with packed open-cell foams in TSA processes for CO2 capture
Abstract
Packed open-cell foams are proposed as an alternative to standard packed bed configuration commonly adopted for the adsorption columns of a temperature swing adsorption process. In this contribution, heat transfer in an adsorption column with a packed foam configuration is investigated by experimental and modeling analysis, in comparison to a standard packed bed. The introduction of the packed foam allows for more rapid temperature transitions and substantial reduction of temperature gradients within the adsorption bed. The impact of this heat transfer enhancement on the separation performance of a temperature swing adsorption process is evaluated by modeling an example post-combustion CO2 capture application. Although the presence of the foam implies a loss of sorbent inventory (-26.5%), higher process productivity (+80%) is achieved thanks to faster temperature swings and more homogeneous temperature distribution within the adsorption columns.
