31 MW FIELD POWER GENERATION
Upgrading Stranded Gas to Power
LOCATION: Roosevelt, UT
MARKET: Power Generation
THE CHALLENGE
The client was interested in implementing a field power generation facility consisting of 1 turbine and 10 Waukesha generators including flare mitigation, utilizing 2 MRUs (Mechanical Refrigeration Unit) to make use of stranded production gas. CANUSA EPC was tasked with the inlet mechanical design, electrical design, and engineering involved in creating the facility.
THE SOLUTION
CANUSA EPC developed a design basis and schedule to meet client timelines. A site visit was conducted to the client yard to gather data on existing switchgear and motor control systems to be re-utilized in the facility. Our team’s construction design and engineering scope included the following:
- Facility site plan
- Facility balance of plant engineering
- PHA report
- Piping design of inlet gas distribution and bill of materials
- Foundation drawings for the turbine package and pipe racks
- Electrical system design with 4160V and 480V
- Arc flash study
THE RESULTS
Facility brings 31.5 MW of energy from a 12 MMSCFD inlet feed.
- Designed for a combined inlet 12 MMSCFD natural gas inlet (8 MMSCFD residue gas and
4 MMSCFD raw gas) - Average power output of 31.5 MW (17.5 MW from the Waukesha generators and 14MW from the turbine)
- Facility was designed for the future use of two MRUs to allow for increased liquid recoveries
