Contacter

A distillation column, extraction column or gas scrubber comprising a contactor for contacting at least two fluid flows, comprising a structure with pores and/or capillaries having a mean diameter of 200 μm to 1 mm for conducting a first fluid, whereby the structure comprises a contact zone not comprising pores and/or capillaries having a mean diameter of 200 μm to 1 mm, which contact zone is designed to conduct a second fluid, and whereby in the contact zone the first fluid can be brought into contact with the second fluid, wherein in the contact zone at least one flow breaker (120.0) is provided for interrupting a flow of the second fluid, wherein the flow breaker (120.0) comprises at least two ledges (120.0), wherein a distributor for distributing the first fluid in the structure is provided at a first end of the contactor and a collector for collecting the first fluid from the structure is provided at a second end of the contactor opposed to the first end, wherein the ledges (120.0) comprise a region (122.0) proximal to the structure, which has a first wettability, and wherein the ledges (120.0) have a region (121.0) distal to the structure, which has a second wettability that is different from the first wettability.
