Abstract: A filter device includes an inlet manifold, an outlet manifold and membrane filter units. Each membrane filter unit has an inlet opening for a fluid flow to be processed, a first outlet opening for a retentate portion of the fluid flow, and a second outlet opening for a remaining portion of the fluid flow. Each inlet opening is fluidly connected to the inlet manifold, and each first outlet opening is fluidly connected to the outlet manifold. The two membrane filter units are staggered and are not axially aligned with respect to each other. One of the membrane filter units is fluidly connected to the inlet manifold and to the outlet manifold via a first set of conduits, and the other membrane filter unit is fluidly connected to the inlet manifold and to the outlet manifold via a second set of conduits.

Abstract: An aqueous CO2 absorbent comprising a combination of 2-amino-2-methyl-1-propanol (AMP) and 3-aminopropanol (AP), or AMP and 4-aminobutanol (AB), is described. A method for capturing CO2 from a CO2 containing gas using the mentioned absorbent, and the use of a combination of AMP and AP, or a combination of AMP and AB are also described.
