Building a low emissions gas plant in Dawson Creek: ARC Resources

ARC Resources lowers greenhouse gas emissions at its Dawson Creek natural gas facility using a variety of technologies.

In 2010, ARC Resources committed to building their Dawson Creek natural gas processing facility Phase 1 and 2 in a manner that would produce fewer greenhouse gas (GHG) emissions than was standard for such facilities at the time. ARC accomplished that goal by using a variety of technologies:

  • Electric-driven compressors were installed instead of using natural gas to compress inlet/sales gas, propane and acid gas at the plant. The plant was also built with an instrument-air system instead of instrument-gas, eliminating the need for venting.   
  • Both phases of the facility were designed to use electricity, but when Phase 1 came online in May 2010, electricity was generated by on-site natural gas turbines. In 2011, with the launch of Phase 2, the entire facility was linked to the B.C. Hydro grid and the on-site generators, powered by natural gas, were deactivated. The facility now runs on hydroelectricity. As a result of these innovations, since 2010 the plant has reduced its emissions by 539,743 tonnes of CO2e, based on an annual average reduction of 67,468 tonnes of CO2e.
ARC continues its work to reduce GHG emissions:
  • Phase 3 of the Dawson Creek facility came on line in 2017. Emission-reducing design elements include a waste heat recovery unit that is estimated to save 1.3 million cubic feet (MMcf) per day of natural gas and avoids approximately 30,000 tonnes of CO2e emissions per year. 
  • In 2018 ARC electrified their Parkland and Sunrise facilities, reducing GHG emissions by approximately 85 per cent or more than 100,000 tonnes of CO2e. 
  • Other pump and instrumentation conversions have reduced emissions by more than 1,000 tonnes of CO2e annually.
