ABSTRACT:
A method is provided for removing mercury from hydrocarbon fluids by high temperature reactive adsorption. A hydrocarbon feed passed through an adsorbent mass including a reactive adsorbent such as silver or copper sulfide on an alumina support. The optimum temperature of the feed to be treated depends upon the 90% boiling points corresponding to heavier feeds. A hydrocarbon condensate feed may be drawn from a stabilizer column in a natural gas processing plant at a temperature in excess of 400.degree. F. If a metallic silver/alumina adsorbent is employed, the adsorbent may be regenerated through high temperature oxidation. Once oxidation is complete, the temperature is lowered in a reducing or inert atmosphere.
