Abstract
Apparatus, and components for use in apparatus, for changing the concentration of a selected gas in a liquid, for example for degassing liquids. In one apparatus, the apparatus has a flow channel (a) through which the liquid is passed, and (b) which comprises a wall comprising a planar separation membrane, and (c) has a height of 0.00025-0.01 and an aspect ratio (width to height) of at least 25:1. One component, which can be used to support a separation membrane, comprises (a) an inner selection plate surface which comprises (i) a selection plate base and (ii) selection plate elements which (a) extend from the base, (b) are separated by intercommunicating selection areas, and (c) have outer surfaces remote from the selection plate base. Another component is a planar separation membrane which comprises (a) a membrane transmission section, and (b) a membrane peripheral member which surrounds the membrane transmission section and which includes location features which facilitate the location of the membrane at a desired position relative to another component.
