摘要

Method for removing a contaminant in vapor phase from a gas stream, apparatus for removing mercury from a gas stream flowing in a gas duct, and method for producing a metallic membrane generally, the present invention provides a method and apparatus for removing a contaminant in The vapor phase from a gas stream.Thereby reducing the concentration of the contaminant in vapor phase in the gas stream.In one implementation, the present invention provides a method to remove a contaminant in vapor phase from a gas stream.Including contacting a gas stream including a contaminant in vapor phase with a first side of a membrane; drinking the contaminant in vapor phase using the membrane; reacting the contaminant in vapor phase in a form interacted the contaminant in vapor phase; transporting the form interacted) The contaminant in vapor phase by the membrane to a second side of the membrane; contacting the second side D.The membrane with a liquid; and dissolve the form interacted the contaminant in vapor phase into the liquid. Methods for making a membrane including a metal for use in the present invention is also described.
