A spacer sheet for use together with another spacer sheet between adjacent membranes (17) in a fluid separation cell, for example an electroldilysis cell, has an open center (2), conduit passages (8 and 9) for the supply and withdrawal of fluid to the chamber formed by the open center (2) between th
A spacer sheet for use together with another spacer sheet between adjacent membranes (17) in a fluid separation cell, for example an electroldilysis cell, has an open center (2), conduit passages (8 and 9) for the supply and withdrawal of fluid to the chamber formed by the open center (2) between the membranes (17), and slots consisting of an offset slot stem (13) and a narrow mouth (14) opening into either the open center (2) or the conduit passages (8 or 9). The slots of the 2 sheets of a spacer assembly cooperate to provide a passage for fluid between the conduit passage and the open center. Identical spacer assemblies may be used between membranes in adjacent cell pairs by positioning the mutually perpendicular. The new spacers are suitable for use in an electrodialysis cell for use in a new method in which ions are removed from a liquid mixture comprising water and water-miscible organic liquid. The deionized liqiud is concentrated and used dowhole, for example in the recovery of methane.

A spacer assembly, for separating membranes of a fluid chamber in a fluid separation cell, said spacer assembly comprising a pair of spacer sheets (1) disposed in overlying coextensive relationship, and in which each spacer sheet (1) has sides surrounding an open centre (2) defining the sarea of the fluid chamber, conduit passages formed by holes (8, 9) in opposite sides of each spacer sheet (1), respectively, for supply and withdrawal of fluid to an associated cell and a plurality of slots (13, 14) arranged substantially uniformly along each of said opposite sides, each slot (13, 14) extending part way only between one of the conduit passages formed by holes (8, 9) and the open centre (2) and each slot having an open slot mouth (30) and a closed slot end distal from said open slot mouth, wherein the slot mouth (30) opens into either the open centre (2) or the respective conduit passage(s) formed by hole(s) (8), said slots (13, 14) being formed in said spacer sheet sides such that facing sides of adjacent slots define teeth (15, 16) that merge at said closed slot ends into a continuous web (20, 21), and in which the opposite sides of each spacer sheet (1) are in overlying relationship with each other so that the slots (14) in one sheet (1) which have their mouths (30) opening into the open centre (2) cooperate with the slots (13) in the other sheet having their mouths (30) opening into the respective conduit passage(s) formed by hole(s) (8) to provide a continuous fluid passage between the conduit passages formed by holes (8, 9) and the open centre (2), in which: the conduit passages formed by holes (8, 9) comprise a supply conduit passage and a withdrawal conduit passage extending along said opposite sides of the spacer sheet (1) and across substantially an entire width of the open centre (2), the slots (13, 14) are distributed substantially uniformly across a width of each conduit passage, a ratio of a width of the mouth (30) of each slot to a thickness of each spacer sheet (1) being in a range of 0.2:1 to 5:1, and at least some of the slots (13, 14) have a widened closed slot end, the width of said widened closed slot end, transverse to the longitudinal axis of said slot, being greater than the corresponding width of said slot mouth and in which substantially all of the slots (13, 14) which do not have said widened closed slot end in one sheet cooperate with a slot (13, 14) which does have said widened closed slot end in the other sheet such that the cooperating slots (13, 14) which do not have said widened closed slot end overlap with said widened closed slot ends of the slots (13, 14) that do have said widened closed slot ends.
