Process Plants

From conceptual design to turnkey process plants, our team of technical experts is constantly improving our project management methods and engineering capability to provide the best performing cryogenic process solutions in all our technologies. We have a strong track-record of supplying custom designed, turnkey cryogenic gas separation and liquefaction plants such as LNG plants, hydrogen/olefin separation systems, and HyCO separation systems.

Liquefied Natural Gas

LNG Plants

Since 2006, EnFlex has successfully executed and delivered engineering, procurement, manufacturing and commissioning of more than 20 small-scale LNG plants. Our unique ability to supply both LNG liquefaction technology and key cryogenic equipment such as brazed aluminum heat exchanger and integrated cold-boxes allows us to provide the best-performing and most cost-competitive LNG liquefaction systems to our customers.

Cryogenic Gas Separation

Hydrogen/Olefins Separation System

EnFlex supplies custom designed, turnkey separation systems for propane dehydrogenation units licensed by Honeywell UOP’s Oleflex™ technology or CB&I’s CATOFIN® technology. Our scope includes technology licensing, engineering, equipment manufacturing, control system integration and system start-up.

We have successfully designed and delivered several cryogenic separation systems for propane dehydrogenation units licensed by CB&I’s CATOFIN® catalytic dehydrogenation technology. Our first turn-key cryogenic separation system designed for the propane dehydrogenation unit licensed by Honeywell UOP’s Oleflex™ technology will start-up by the end of 2018.

 

HyCO Separation System

EnFlex has successfully delivered six hydrogen carbon monoxide (HyCO) cryogenic separation systems using our proprietary process technologies. Three of these systems are currently operating and the remaining systems are undergoing fabrication.
