High Capacity Regenerable Sorbent For Removal Of Mercury From Flue Gas
US Patent:
6719828, Apr 13, 2004
Filed:
Apr 26, 2002

International Classification:
B01D 5304
US Classification:
95134, 95900, 96108, 423210
Abstract:
A high-capacity regenerable sorbent for removal of mercury from flue gas and processes and systems for making and using the sorbent. A phyllosilicate substrate, for example vermiculite or montmorillinite acts as an inexpensive support to a thin layer for a polyvalent metal sulfide, ensuring that more of the metal sulfide is engaged in the sorption process. The sorbent is prepared by ion exchange between the silicate substrate material and a solution containing one or more of a group of polyvalent metals including tin (both Sn(II) and Sn(IV)), iron (both Fe(II) and Fe(III)), titanium, manganese, zirconium and molybdenum, dissolved as salts, to produce an exchanged substrate. Controlled addition of sulfide ions to the exchanged silicate substrate produces the sorbent. The sorbent is used to absorb elemental mercury or oxidized mercury species such as mercuric chloride from flue gas containing acid gases (e. g. , SO , NO and NO , and HCl) and other gases over a wide range of temperatures.

Method For Removal And Stabilization Of Mercury In Mercury-Containing Gas Streams
US Patent:
6942840, Sep 13, 2005
Filed:
Sep 23, 2002
Appl. No.:
10/253944
Inventors:
Thomas E. Broderick - Arvada CO, US
Assignee:
ADA Technologies, Inc. - Littleton CO
International Classification:
B01D053/14
US Classification:
423101, 95152, 95195, 95234, 96235, 210914, 422168, 423210, 4232155
Abstract:
The present invention is directed to a process and apparatus for removing and stabilizing mercury from mercury-containing gas streams. A gas stream containing vapor phase elemental and/or speciated mercury is contacted with reagent, such as an oxygen-containing oxidant, in a liquid environment to form a mercury-containing precipitate. The mercury-containing precipitate is kept or placed in solution and reacts with one or more additional reagents to form a solid, stable mercury-containing compound.
