Gas separation elements and modules

A process for separating a feed gas comprising a polar gas and a non-polar gas into a permeate gas and a retentate gas, one of which is enriched in the polar gas and the other of which is depleted in the polar gas, the process comprising passing the feed gas through a gas separation module comprising: (i) a feed carrier comprising a membrane envelope and a feed spacer located within the membrane envelope; and (ii) a permeate carrier comprising: (a) a macroporous sheet; and (b) a protective sheet; and wherein: i) the feed gas is fed along the feed spacer of the feed carrier and a part of the feed gas passes through the membrane envelope and into the permeate carrier to give the permeate gas and a part of the feed gas is rejected by the membrane to give the retentate gas; ii) the protective sheet shields at least a part of the membrane envelope from contact with the macroporous sheet; and iii) the protective sheet comprises a non-woven material.

Spiral wound membrane module for gas separation with protection layer

A process for separating a feed gas comprising polar and non-polar gases into a gas mixture enriched in polar gas(es) and a gas mixture depleted in polar gas(es), the process comprising passing the feed gas through a gas separation unit comprising at least two gas-separation modules in order of increasing selectivity for the polar gas(es), wherein the feed gas entering the gas separation unit comprises more than 35 mol % and up to 90 mol % of polar gas(es).

Gas separation process

A process for separating a feed gas comprising polar and non-polar gases into a gas mixture enriched in polar gas(es) and a gas mixture depleted in polar gas(es), the process comprising passing the feed gas through a gas separation unit comprising at least two gas-separation modules in order of decreasing selectivity for the polar gas(es), wherein the feed gas entering the gas separation unit comprises 1 to 35 mol % of polar gas(es).

Spiral wound gas filtration modules and components thereof

A gas separation module comprising gas separation elements, said elements comprising at least two membrane sheets and a permeate carrier sandwiched between the membrane sheets, wherein the permeate carrier comprises at least two macroporous layers and a gas-impermeable sheet located between the macroporous layers.

Spiral wound gas separation membrane modules

A membrane envelope comprising a feed spacer, one or more membrane sheets and an adhesive, to give a glue line laminate having a tensile E-modulus of at least 1600 N/mmand/or an elongation at break of 13% or less.

Spiral wound gas filtration module with specific adhesive

A gas separation module comprising: (a) a permeate collection tube; (b) a membrane envelope wound spirally around the tube to provide a wound membrane structure comprising two end faces; and (c) an anti-telescoping device (ATD) secured to the permeate collection tube, the ATD comprising: (i) an inner peripheral part, (ii) an outer peripheral part which surrounds the inner peripheral part, (iii) one or more connection parts which connect the inner peripheral part and the outer peripheral part and which contacts with one of said end faces; (iv) vents which allow gas to flow through the ATD; wherein the ATD satisfies Formula (1): (L CP&#x2212;L contact)/(L VENT)=R Formula (1) wherein: R is from 1.47 to 1.88; L VENT is the cross sectional area of the vents which allow gas to flow through the ATD; L CP is the total area inside the outer peripheral part; and L contact is the contact area of the connection parts and the end face of the wound membrane envelope. Clamps are also claimed.

Antitelescoping device and clamp for spiral wound modules comprising a vent
