Gas Processing & Treatment Projects
Equinox provides world class expertise in gas processing, gas treating and liquids recovery facilities design. We have designed and constructed over 80 gas processing trains worldwide. Our experience includes a wide range of processing and treating facilities including refrigeration plants, amine sweetening, sulphur recovery, mercury removal, acid gas transportation and disposal, glycol dehydration, mole sieve dehydration, cryogenic processing plants, turbo-expanders, NGL recovery and fractionation.
Wapiti Gas Processing (200 MMscfd)
Pipestone Liquids Hub (22,000 bpd)
Glacier Sour Gas Plant Expansion (400 MMscfd)
Kakwa Sour Gas Plant (200 MMscfd)
Equinox executed the FEED, Detail Design, installation, and commissioning of a large sour, deep-cut gas plant facility. Rolled out in three phases. the scope included; Phase I – 50 MMscfd sweet gas plant, Phase II – 200 MMscfd gas plant with deep cut (turbo-expander) liquids recovery, and Phase III – 200 MMscfd Amine Sweetening. Many of our processing projects include condensate stabilization, turbo-expander processes for increased C2+ recovery, propane refrigeration processes for C3+ recovery, liquid fractionation trains as well as condensate, NGL and LPG storage.
Simonette Gas Plant
FEED and Detail Design and installation of 50 MMscfd expansion of the existing Simonette plant. The process train includes slug catcher, liquids / liquids separator, inlet separation, condensate stabilizer, stabilizer overheads compressor, inlet/sales compression (2370 HP), refrigeration, de-ethanizer overheads compressor, LACT units (sales gas, condensate, LPG), produced water injection, storage for produced water and condensate. This will also provide incremental LPG production of 2,700 bpd and incremental stabilized condensate production of 9,000 bpd.

Equipped with inlet separation, condensate blowcase, compression/dehydration to transmit sour process gas and condensate liquids through 22 km of 8″ pipeline to the Peggo Processing Plant. New train includes inlet separation & compression, amine sweetening, and dew point control refrigeration.
West Doe Sour Gas Plant (100 MMscfd)
FEED & Detail Design for a sour gas plant with three process trains totaling 100 MMscfd with process gas conditions of 2.6% H2S and 3.0% CO2 from the Montney. Facility includes containing inlet separation, inlet compression, amine sweetening, refrigeration, liquid fractionation and stabilization, acid gas compression, vapour recovery and recycle system, sales compression. Power generation includes one Solar Taurus 59 (4500 KW) genset and five 550 KW natural gas driven electrical generators). Also includes storage for produced water, condensate and NGL with truck-out facility.
Pouce Coupe Sour Gas Plant (60 MMscfd)
A modular facility designed for ease of transportation and remote assembly. 60 MMscfd capability to handle inlet process gas containing 1.5% H2S and 3.0% CO2. The process trains contain, line heating, inlet separation/ pipeline slug catcher, amine sweetening, refrigeration, liquid fractionation and stabilization, acid gas compression, vapour recovery, recycle system and final sales compression. The Pouce Coupe Gas Plant also contains storage for produced water, condensate and NGL with truck out facilities. Acid gas produced from the amine plant is disposed of onsite using a (500 hp) electric driven compressor.
We are the only Canadian EPCM, and one of few worldwide, with approval for detailed engineering design of sour gas and sulphur recovery projects regarding THIOPAQ Biological Desulphurization Process. This technology removes H2S from natural gas and converts it directly to elemental sulphur utilizing naturally occurring, non-genetically modified microorganisms of the Thiobacillus family. We provided services for the first (and only) high-pressure natural gas applications including Bantry Gas Plant (12 MMscfd, 1 t/d sulphur) and the Valhalla Gas Plant (2 MMscfd, 2 t/d sulphur).
