Abstract
The present disclosure provides improved systems, assemblies and methods to remove and recover COfrom emissions. More particularly, the present disclosure provides improved membrane contactors configured to remove COfrom flue gas by temperature swing absorption. In exemplary embodiments, the present disclosure provides a novel hollow fiber membrane contactor that integrates absorption and stripping using a nonvolatile reactive absorbent (e.g., 80% polyamidoamine (PAMAM) dendrimer generation 0, and 20% of an ionic liquid (IL)). Equilibrium COabsorption in the nonvolatile viscous mixed absorbent is as high as 6.37 mmolCO/g absorbent in the presence of moisture at 50° C. A novel membrane contactor is provided for COabsorption and stripping via a process identified as temperature swing membrane absorption (TSMAB). The contactor integrates non-dispersive gas absorption and hot water-based COstripping in one device/assembly containing two sets of commingled hollow fibers.
