Arc Resources – Sunrise

Gas Liquids Engineering Ltd. (GLE) provided FEED and preliminary engineering for a 133 MMSCF/d (2 x 66.5 MMSCF/d trains) greenfield sour gas processing facility located in Northeast British Columbia. The equipment was to be installed in two phases, with the first phase having the shared equipment installed. The plant was to consist of the following major processing units:

  • Sales compression – Four 4500 hp 3-stage compression packages (2 per train)
  • Condensate stabilization
  • Acid gas compression / injection (1.2 MMSCF/d, 200 hp, 80% CO2, 20% H2S)
  • Sour water stripping
  • Inlet slug catching and separation (360 bbl/d pigging volume)
  • Inlet compression
  • Amine Sweetening (50% wt MDEA solution at 67 US gpm)
  • Gas chilling

Utility systems included:

  • Power generation / BC Hydro substation (9MW from BC Hydro /w 9 MW natural gas driven or turbine powered generation as backup, 1 MW essential services natural gas powered generator)
  • Recycle Compression – One (1) small electric driven compressor was to be installed in phase 1, with two (2) additional electric driven compressors to be installed in phase 2.
  • Flare System (Designed to handle 133 MMSCF/d)
  • Produced liquids storage (the plant was to produce C3+ NGL product, and have one (1) 40,000 US Gallon NGL storage bullet in phase 1, with two (2) additional bullets to be installed in phase 2)
  • Utility / process heat medium (24 MMBtu/hr)
  • Vapour recovery
  • Instrument air (125 hp)
  • Utility gas (Fuel, purge, and blanket)
  • Truck out area
  • Heli-pad

The plant was eventually built by a different engineering firm, but scaled back to 60 MMSCF/d. The plant came online in late 2015.
