Location: Shute Creek Treating Facility, LaBarge, Wyoming, USA
Start Date: 2008 (4 Mt/yr); 2010 (6 Mt/yr)
Size: 6 Mt/yr (365m cubic feet/day)
CO2 Source: Natural gas stream from fields in Wyoming
Storage: Pipeline to EOR sites in the surrounding area
The produced CO2 is sold to companies for EOR in nearby areas. The cost to expand capture facility was $86 million dollars.
Production of natural gas from the LaBarge field in southwest Wyoming began in 1986. This gas contains high concentrations of CO2. The Shute Creek Treating Facility (SCTF) processes the gas produced from the LaBarge field. The gas composition entering Shute Creek is 65% CO2, 21% methane, 7% nitrogen, 5% hydrogen sulfide (H2S) and 0.6% helium. The SCTF separates CO2, methane, and helium for sale and removes hydrogen sulfide for disposal. A concentrated acid gas stream of about 60% hydrogen sulfide and 40% CO2 is injected into a carefully selected section of the same reservoir from which it was produced, safely disposing of the hydrogen sulfide along with approximately 400,000 tons of CO2 per year.
ExxonMobil uses its Controlled Freeze Zone™ technology, known as CFZ™. CFZ™ is a single-step cryogenic separation process that freezes out and then melts the carbon dioxide and removes other components including hydrogen sulfide, which is found in sour gas.
ExxonMobil completed its expansion of the CO2 capture facility in December 2010. This has resulted in 50% more CO2 capture than the previous plant.
