Abstract
A module (1) for rigid cylinder membrane elements (2) for separation, filtration, or catalytic transformation, the elements (2) being received in a vessel which is generally cylindrical and parallel thereto, and closed by a first end plate (4) and a second end plate (5) to which the ends of the elements (2) are fixed by means of seals (6,7). The end plates are interconnected by at least one spacer constituted by at least three juxtaposed oblong parts (10, 20, 30) made of materials selected for reducing the expansion differences that would otherwise occur on a change in the temperature of the vessel and its membrane elements.
