Abstract
A contactor media includes continuous surface segments, wherein a first continuous surface segment has at least 50% of its surface area follow at least one of: (a) a contour of a first zero-thickness surface having a Gaussian curvature (“Gc”) of −400 mm−2≤Gc<−0.01 mm−2; and (b) a contour of a second zero-thickness surface having at least one principal curvature (ki) of −20 mm−1≤ki<−0.1 mm−1; and wherein the first continuous surface segment provides at least: (a) a total liquid hold-up of between about 1 kg/m3 to about 800 kg/m3 or (b) a static liquid hold-up of about 0.1 kg/m3 to about 800 kg/m3.
