Equipment / Processing
Cryogenic / Deep Cut
Trusted Cryogenic Solutions for 40+ Years
Cryogenic processing cools liquids-rich natural gas to sub-zero temperatures to extract liquids, increasing revenue for natural gas producers. Our modular plants provide industry-leading performance and reliability.
The Enerflex Edge
Flexibility in Design and Operation
Our plants are designed for flexibility, adapting to various site needs and process configurations. Fully digitized controls provide smooth integration, ensuring efficient, reliable operations.
Maximized Recovery with Advanced Turboexpanders
Our cryo plants use cutting-edge turboexpanders to achieve deep ethane and propane recoveries of up to 99%, even at temperatures as low as -112°C, ensuring producers maximize revenue.
Customized to Your Needs
Our cryogenic systems are tailored to your specific operational requirements. We maximize recovery, optimize throughput, and handle complex gas compositions, delivering solutions designed for you.
Solutions
Our designs for cryogenic plants are modular and flexible, offering a variety of options.
- Molecular sieve dehydration
- Turboexpanders that cool the gas while generating mechanical energy to drive the booster compressor, which partially recompresses the residue gas stream
- Optimized thermal integration, resulting in reduced power consumption and CAPEX
- Mechanical refrigeration unit add-ons for supplemental cooling of highly liquids-rich gas
- Additional options such as inlet and residue compression, mercury removal, a hot oil system, pipeline pumps, amine treating, and TEG dehydration
Case Study
Custom 300 MMSCFD Multi-Process Cryogenic Plants
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.
