Apparatus for contacting first and second fluids at elevated pressures with a membrane such that one or more components of one of the fluids passes through the membrane into the other fluid, comprising a housing e.g. a pressure vessel (4), and a membrane module (20) housed in the pressure vessel and having a first fluid inlet (8a) and a first fluid outlet (8b) and a second fluid inlet (9a) and a second fluid outlet (9b), wherein a seal (61) extends round the membrane module and seals between an outside wall of the membrane module and an inside wall of the pressure vessel so as to separate the first fluid inlet from the first fluid outlet.
Apparatus for contacting first and second fluids at elevated pressures with a membrane such that one or more components of one of the fluids passes through the membrane into the other fluid, comprising a housing, and a membrane module housed in the housing and having a first fluid inlet and a first fluid outlet and a second fluid inlet and a second fluid outlet, wherein a seal extends round the membrane module and seals between an outside wall of the membrane module and an inside wall of the housing so as to separate the first fluid inlet from the first fluid outlet.
Apparatus as claimed in any preceding claim, wherein the membrane module has a cross-sectional shape corresponding substantially to that of the housing so as to fit closely therein.
Apparatus as claimed in any preceding claim, wherein the housing has at least one full diameter flanged opening for insertion of the membrane module.
Apparatus as claimed in any preceding claim, wherein the first-mentioned seal is received in a groove in the housing.
Apparatus as claimed in any preceding claim, wherein the membrane module comprises a plurality of membrane layers, each membrane layer comprising a plurality of membrane tubes arranged side by side with connecting portions connecting laterally adjacent membrane tubes, and the membrane layers being stacked in alternation with spacers.
Membrane contactor apparatus comprising a bundle of axially extending membrane tubes arranged for a first fluid to flow outside of said tubes and for a second fluid to flow axially inside said tubes from an axial end of the bundle to an opposite axial end thereof, such that one or more components of one of the fluids passes through walls of the membrane tubes into the other fluid, the apparatus further comprising inlet means disposed axially inwardly of one of said axial ends of the bundle for introducing said first fluid into the bundle, wherein the inlet means extends peripherally round the bundle and is arranged to permit flow of said first fluid laterally into the bundle substantially around its entire periphery.
