Challenge:

Enerflex was tasked with engineering, designing, manufacturing, and commissioning two custom built, multi-process 300 MMSCFD cryogenic plants. The client partner needed flexibility for various operating modes—GSP, SCORE, and SRC—along with deep propane recovery, and minimal compression power to reduce long-term operating costs. 

Solution:

We provided a stick-built, semi-modular design with two cryogenic NGL recovery processing trains. These trains featured amine units, molecular sieve dehydration, refrigeration compressors, and centrifugal residue compressors. A common NGL system enabled the flow of product to a Y-grade pipeline for fractionation.

Outcome:

The project, located in DJ Basin, Colorado, USA, was completed on time, within budget, and with zero safety incidents. Enerflex’s custom design enabled high propane recovery and provided flexibility for future ethane markets. The plant has exceeded design expectations, and led to additional work across all four project sites.

Challenge:

We were asked to deliver a 200 MMSCFD cryo plant integrated with a 10,000 BBL/D stabilizer, more than doubling the customer’s processing capacity. The clientt, based in Powder River Basin, Wyoming, required a custom solution that prioritized propane recovery, with flexibility for future ethane expansion. 

Solution:

We designed a plant with a two-tower stabilizer to minimize compression. Key components included molecular sieve beds, a 5,000 HP residue gas compressor, and onsite storage for NGL and condensate. The design focused on 94% propane recovery, optimizing energy use and eliminating the need for a refrigeration system. 

Outcome:

The project was completed on time, with Enerflex managing the entire balance of plant design, construction, and commissioning. The plant’s flexibility maximized propane and condensate value, and Enerflex’s site team efficiently managed over 400 workers, delivering the project within budget and without incident.
