Inga Sour Gas Compressor Station

October 15, 2019

Equinox successfully executed a complete facility relocation and expansion of our Client's Inga Sour Gas Compressor Station.

The assets for the station, originally the Fortune Creek Compressor and Dehydration Station in the Horn River Basin of British Columbia, were acquired by our Client and then relocated 400 km (250 miles) to the Inga new gas compression and dehydration station 70 km (43 miles) northwest of Fort St. John, British Columbia.

This project involved the relocation of an existing 120 MMscfd sour gas compression facility, as well as the addition of three new inlet vessels, an oil and water tank farm, and water and oil sales pumps. The facility also included two large frac-water ponds with access to both truck-out and pipelines for distributing frac water. The relocation was expanded to process 6,000 bpd with future expansion to 12,000 bpd.

• Modularized Inlet Receivers to have 8 different inlets with the need for only two pig receivers
• Flipped the orientation of the piperack to align the existing layout with the new pipeline ROWs locations
• Added an oil treater and tanks to process the increased sour oil service
• Segregated the gas trains to have a sweet and sour train
• Designed the plant for future capabilities of an amine and/or refrigeration train

The existing facility was deconstructed and upgraded to be shipped as modules to the new location about 400 km away. The equipment was rebuilt in the same configuration, except with key upgrades and modifications designed by Equinox Engineering. Key upgrades include:

• 4 x 3612 Cat-driven Ariel Sour Gas Compressor units
• 2 x TEG Gas Dehydration Units
• 2 x Inlet Slug Catchers
• 1 x Oil Treater
• 1 x Two-Stage Sour Gas VRU
• 5 x Oil Tanks
• 4 x Water Tanks
• Associated utilities (I/A, Heat Medium, Fuel Gas)
