Abstract

Plates are fabricated e.g. by hot pressing extruded sheet, pref. of polystyrene expanded with CFCl3, with pressure applied mainly to central region, so that flow channel grooves and membrane supports are comparatively rigid, while edges, destined to be clamped in press of exchanger are compressible, to obtain a good seal with the membrane sheets with which they are interleaved. Alternatively the same advantages may be obtd. using a rigid central section welded to, or fitting in, an outer rim of expanded plastic. No gaskets are required, plates are light, easily fitted, and cheap enough to be disposable in sterile applications. Sterilisation may be by gamma-rays.
