Process technology licensor GTC Technology reached a global
agreement with ConocoPhillips for its selective partial
oxidation of sulfur (SPOC) technology for sulfur
recovery, the company said on Tuesday.
ConocoPhillips has a long heritage of technology innovation,
including technologies for LNG, delayed coking, clean
fuels, gasification and alkylation, GTC officials said.
GTC says its
SPOC technology is the most significant innovation in
the modified Claus technology space in the last 30
Given the prevalence of modified Claus
technology, SPOC technology is expected to impact the global
sulfur recovery space for the foreseeable future, according to
The agreement expands GTCs platform of acid gas
removal technology, which currently includes
GT-CO2, a process technology for CO2 removal;
GT-SSR, a Claus process for sulfur recovery; and GT-DOS,
an innovative direct oxidation technology.
SPOC technology eliminates the Claus furnace and
addresses many of the endemic issues associated with
conventional modified Claus technology, such as COS and CS2
formation, and challenges with startup and shutdown, said
Dr. Matt Thundyil, sulfur business leader for GTC.
In addition, it is anticipated to offer better
efficiencies than conventional modified Claus technology with
significant savings in capital cost, he added. This
technology may also be able to upgrade conventional modified
Claus plants, delivering improved performance with minor
This collaborative agreement with GTC allows us to
bring valuable innovation to a marketplace that has been
seeking better technology, said Merl Lindstrom, interim
senior vice president of technology at ConocoPhillips.
ConocoPhillips developed and tested the SPOC technology and believes it sets a
new cost and performance benchmark for sulfur removal
processes, Lindstrom added.
ConocoPhillips is the third-largest integrated energy
company in the US and the fourth-largest refiner worldwide.
