Equinox has significant compression experience and has successfully designed and installed over 300 compression packages, including over 60 large horsepower reciprocating and centrifugal projects. In addition, we have executed hundreds of compression studies and evaluations. Our extensive gas compression experience includes centrifugal, reciprocating, rotary screw and vane type compressors for all sweet and sour gas applications, as well as gas turbine, natural gas engine, steam turbine and electric drivers.
We have an excellent reputation and extensive expertise with the installation of compression including service (sweet, sour and acid gas), compressor types (reciprocating, centrifugal, screw, and rotary vane), and driver types (gas engine driven, electric motor driven or turbine driven) compressors. Our extensive experience has led to a unique approach to modularization for the installation of large compressors that results in substantially more economic installation cost metrics and accelerated project schedules.
Selection and Optimization Studies
With decades of optimization and compressor selection studies completed, Equinox has an extensive database of compressor selection studies focused principally on determining optimum compressor strategies and life cycle costs – with specific emphasis on key criteria, such as CAPEX, OPEX and maintenance costs, reliability and performance. Our optimization studies focus on much of the same criteria as the selection studies but are tailored to evaluating cost effective solutions of modifying or upgrading existing infrastructure within brownfield environments. These studies also tie into various Carbon Capture treatments and options.
Santos GLNG - Arcadia Central Processing Facility (80 MMscfd)
Santos GLNG - Scotia Central Processing Facility (90 MMscfd)
Equinox executed the Concept, FEED and Detail Design for the Scotia Central and Flank CF1 Plant Expansion Project located in eastern Queensland, Australia. The brownfield expansion leveraged the Equinox ‘Standard Design’ and included the addition of main compression (4 x gas engine driven CAT 3608 and Ariel reciprocating JGD/4, 4-stage).
Placid Compressor Station (70 MMscfd)
Equinox provided engineering, procurement, construction support and commissioning for this greenfield, sour compression station. The project’s compression included:
- 1 x Ariel reciprocating JGC/4 with Cat 3608 (2,445 HP) driver
- 3 x Ariel reciprocating JGD/6 with Cat 3612 (3,875 HP) driver
Inga Compressor Station (120 MMscfd)
Deep Basin Compression
FEED and Detail Design for a program of 12 standalone compressor stations throughout northwest Alberta. A modular design provides optimized installation in remote northern terrain. Each typical booster compressor station accepts raw gas from 6 – 10 wellsites and includes: an inlet separator/blowcase (48-inch separator and a 24-inch blowcase), vent stack, knockout drum and 1,478 hp compressor package.
