ABSTRACT:
Mercury is removed from a gaseous hydrocarbon stream by passing the stream through an in-line mixer which includes mixing elements which have gas-contacting surfaces of an amalgam-forming metal. Preferred amalgam-forming metals are gold, silver or a combination thereof. A specific in-line mixer has static mixing elements which are disposed along the length of the mixer, preferably, the mixing elements are helically disposed along the length of the mixer. Other contaminants such as water and residual H.sub.2 S and CO.sub.2 are removed from the gas stream by a gas purification system which includes the in-line mixer and a desiccant bed modified for removing mercury and other contaminants. The modifications to the desiccant bed include a porous gold and/or silver containing layer, i.e., a gold and/or silver wire screen or packed gold and/or silver wool, and a protective layer of alumina pellets having an active compound such as copper hydroxide, copper oxide and copper sulfide impregnated therein.
