Generally, the present invention provides a method and apparatus (100) for removing a vapor phase contaminant from a gas stream, thereby reducing the concentration of the vapor phase contaminant in the gas stream. In one embodiment, the present invention provides a method for removing a vapor phase contaminant from a gas stream, comprising contacting a gas stream comprising a vapor phase contaminant with a first side of a membrane (140); sorbing the vapor phase contaminant using the membrane (140); reacting the vapor phase contaminant into an reacted form of the vapor phase contaminant; transporting the reacted form of the vapor phase contaminant through the membrane (140) to a second side of the membrane (140); contacting the second side of the membrane (140) with a liquid; and dissolving the reacted form of the vapor phase contaminant into the liquid. Methods for making a membrane comprising a metal for use in the present invention is also described.
En règle générale, l'invention concerne un procédé et un dispositif pour la suppression de contaminant en phase vapeur dans un flux gazeux, permettant de réduire la concentration de ce contaminant dans le flux. Selon une variante, on met en contact le flux gazeux à contaminant en phase vapeur avec un premier côté de membrane ; viennent ensuite la sorption du contaminant par la membrane, la réaction du contaminant sous une forme transformée, le transport de cette forme vers un second côté de la membrane, le contact entre ce côté et un liquide, et la dissolution de ladite forme dans le liquide. On décrit aussi des procédés d'élaboration de membrane comprenant un métal aux fins de l'invention.
