Abstract: The invention provides a flow module comprising sandwiched plate elements, with at least one of each pair of adjacent plate element surfaces having a profiling which has a linear parallel construction so that a plurality of linear parallel flow ducts is formed between adjacent plate elements. These flow ducts can be charged with a first and a second fluid in an alternating manner by way of feeding and removal ducts formed by mutually aligned openings in the plate elements. To seal off the flow spaces and the feeding and removal ducts, seals are provided, and the openings for the feeding and removal ducts extend essentially across the whole end area of the profiling so that a distinct feeding and removal space is formed. According to the invention, for a mechanical stabilization several webs are arranged in the openings for the feeding and removal ducts in the profiled plate elements. These webs which are arranged in the inlet area or outlet area of the profiling end below the plate element surface.

Abstract: Apparatus for separating a gas-water vapor mixture having a cooling liquid space for circulation of a cooling liquid, at least one duct arranged in the cooling liquid space and a separation water space arranged adjacent the duct. The walls of the duct are made of a permeable membrane so that water condensed from the gas as it flows through the duct can permeate into the separation water space.
