A gas separation element comprising a membrane sheet and a permeate spacer, wherein the membrane sheet comprises a porous support and a discriminating layer, CHARACTERISED IN THAT:

Gas separation elements and modules

A composite membrane comprising: a) a porous support; b) a gutter layer; and c) a discriminating layer which satisfies Formula (1): wherein: &#xd8; is &#x3c;4; x is the arithmetic mean of N measurements of the thickness of the discriminating layer and has a value of between 30 and 150 nm; N is at least 100; xis the thickness in nm of an individual measurement of thickness within the N measurements; x&#x3e;x&#x3e;0; and n is the number of individual thickness measurements where x&#x3e;x, &#x3e;0 

Membranes

A composite gas membrane comprising: a) a porous support; b) an activated gutter layer; c) a discriminating layer located on the gutter layer; and d) optionally a protective layer on the discriminating layer; wherein the said layers remain in place when a peeling force of 2.5 N/1.5 cm is applied to the outermost of said layers.

A composite membrane comprising: a) a porous support; b) a gutter layer, a portion of which is present within the support and a portion of which is outside of the support; and c) a discriminating layer on the gutter layer; wherein: (i) the portion of the gutter layer outside of the support has an average thickness (GL) of 10 nm to 900 nm; and (ii) the portion of the gutter layer present within the support has an average thickness (GL) of 10% to 350% of GL.

Curable compositions and membranes

A composite membrane comprising: (a) a porous support; (b) a gutter layer; (c) a discriminating layer having an average thickness of at most 90 nm; and (d) a protective layer having an average thickness 150 nm to 600 nm comprising dialkylsiloxane groups.
