A process for preparing membrane layers employing an apparatus suitable for plasma surface treating (e.g. forming a membrane layer on a substrate) which comprises a plasma generation section which is operable at least at substantially atmospheric pressure and is in communication via at least one plasma inlet (e.g. a nozzle) with an enclosed plasma treating section which is operable at a lower pressure than the plasma generation section, and wherein the plasma treating-section is in communication with an inlet for a fluid (e.g. polymerizable) reactant. A plasma beam generated in the apparatus and containing at least one fluid reactant impinges on the surface of a substrate to form a membrane layer.

Method for plasma surface treating and preparation of membrane layers

The invention relates to a process for preparing non-porous, selective membrane layers by contacting a permeable, continuous substrate (e.g. comprising a non-porous, permeable intermediate layer and a microporous support layer) with the glowing zone of a plasma.

Process for preparing non-porous, selective membrane layers

An apparatus suitable for plasma surface treating (e.g., forming a membrane layer on a substrate surface) comprises a plasma generation section which is operable at least at substantially atmospheric pressure and is in communication via at least one plasma inlet (e.g., a nozzle) with an enclosed plasma treating section which is operable at a lower pressure than the plasma generation section, and wherein the plasma treating-section is in communication with an inlet for a fluid (e.g., polymerizable) reactant used to form a layer on the substrate surface.

Apparatus for plasma surface treating and preparation of membrane layers

A low melting, eutectic melt salt composition comprising Li.sub.2 CO.sub.3, Na.sub.2 CO.sub.3 and K.sub.2 CO.sub.3, also containing MnCO.sub.3, is disclosed including its use as a melt in the process for the removal of contaminants, e.g., H.sub.2 S, COS and/or fly ash, from gases obtained by partial oxidation/combustion.
