Debolt Frac Water Treatment Facility

The Debolt water treatment plant is a proprietary grassroots facility located approximately 20 KM south of the North West Territories border in the farthest reaches of northeast British Columbia. The EPCM project was completed to install a new water treatment plant at the existing Etsho compressor and dehydration facility. The scope of the project was to install a new sour produced water treatment plant including a stripping tower, a degassing tank, and a proprietary, confidential process to reduce the H2S content of the water to 0 ppm. The design capacity of the facility is 16,000 m3/d of inlet sour produced water.

Tooga Gas Plant (60 TJ)

The new Tooga Gas Plant is a modularly designed facility specifically layed out for ease of transportation and assembly in a remote fi eld in north east British Columbia Canada. The Tooga Gas Plant is designed with a 60 TJ capability to handle inlet process gas containing 50 ppm H2S and 3.5% CO2. This plant was added to the Duke Energy compressor site; the initial facility was equipped with inlet separation, condensate blowcase, compression and dehydration to transmit sour process gas and condensate liquids through 22 km, 8 inch diameter pipeline to the Peggo Sour Gas Processing Plant. The new processing train includes inlet separation, inlet compression, amine sweetening, and dew point control refrigeration to transmit sales pipeline specification gas to the Peggo Gas Plant.

THIOPAQ Bio-Desulphurization

Equinox is the only Canadian EPCM and one of the few in the world to be an approved engineering service provider for detailed engineering design of sour gas and sulphur recovery projects with respect to the THIOPAQ Biological Desulphurization Process. This technology removes H2S from natural gas streams and converts it directly to elemental sulphur utilizing a naturally occurring, non-genetically modified microorganism from the Thiobacillus family. In Canada, Equinox provided the EPCM services for the first and only high-pressure natural gas applications including the Bantry Gas Plant (12 TJ, 1 t/d sulphur) and the Valhalla Gas Plant (2 TJ, 2 t/d sulphur).
