THE TOFIK K. KHANMAMEDOV COMPANY Received the Notice of Allowance from U.S. Patent Trademark Office on the Patent Application for SHIFT-CLAUS(R) and TC(TM) Catalytic Sulfur Recovery Processes

Mar 11, 1999, 00:00 ET from THE TOFIK K. KHANMAMEDOV COMPANY

    HOUSTON, March 11 /PRNewswire/ -- A U.S. patent will be awarded to
 Dr. Tofik K. Khanmamedov in 1999, which strengthens his exclusive position on
 the family of SHIFT-CLAUS(R) and TC(TM) catalytic processes for sulfur
 recovery and expands his patents estate.
     These technologies provide a new concept for sulfur recovery from acid
 gases with different concentration of H2S and significantly reduces sulfur
 emissions from sulfur units.
     The distinguished side of SHIFT-CLAUS(R) technology is that COS and CS2
 are involved in sulfur formation in SHIFT-CLAUS(R) reactor, contrary to known
 competitors' processes where COS and CS2 after first catalytic reactor of
 Claus unit are considered as a lost sulfur recovery.
     SHIFT-CLAUS(R) recovers sulfur from acid gases of refineries and other
 sources and leads to +99% recovery in three catalytic beds Claus unit.  Any
 conventional Claus unit can be converted to SHIFT-CLAUS(R) by utilizing
 proprietary catalysts.
     The TC(TM) thermo-catalytic process was developed specifically for sulfur
 recovery from "diluted" acid gases that can not be treated with the
 conventional Claus process.  This technology also utilizes proprietary
 catalysts and arranges flameless combustion of H2S in the thermo-catalytic
 reactor.  TC(TM) excludes well-known split-flow configuration of the Claus
 process and avoids related operating problems.  Any Claus unit can be
 converted to TC(TM).
     SHIFT-CLAUS(R) and TC(TM) do not require major changes of existing process
 configuration or equipment.
     THE TOFIK K. KHANMAMEDOV COMPANY is a United States based process
 technologies-developing company, that also licenses patented family of
 HIGHSULF(TM) gas sweetening and tail gas treatment processes.
     THE TOFIK K. KHANMAMEDOV COMPANY (est. 1995), a process technology leader,
 continues to develop new technologies for the oil, gas and petrochemical
 industries.  There has been strong interest in these technologies from major
 refineries and gas processing companies worldwide.
     The Company's strategy is to focus its internal resources on research,
 development and marketing while taking advantage of strategic alliances to
 assist in continued growth.
