New Gas-Separation Technology Reduces Cost, Weight, and Footprint

Hydrocarbon processing and treating systems often require large and elaborate surface facilities. When operating in challenging locations, such as deep water or the Arctic, these systems can be expensive. This paper discusses a new adsorption-based gas-separation technology platform to address these challenges.

The technology uses rapid pressure- and temperature-swing cycles to reduce equipment size and weight and the overall gas-treating footprint by approximately 50% compared with conventional technologies. The savings are particularly beneficial in locations where space is limited. Furthermore, the technology is well suited for skid-based deployment, which provides execution efficiencies.

While the technology platform is broadly applicable for a variety of upstream gas separations, development is currently focused on deep dehydration and carbon dioxide (CO2) removal before cryogenic gas processes, such as liquefied natural gas (LNG) or natural gas liquid (NGL) recovery.

Extensive fundamental research, including laboratory and pilot testing, has been completed to demonstrate technical feasibility.

Construction of a field research and demonstration facility is under way as of this writing to demonstrate scaled-up operation over a wide range of operating conditions.
