Pressure Swing Adsorption for Natural Gas Separation – Maximizing the Value of NGL's and Emissions Reductions at Facilities

Abstract We developed the NGL Recovery Solution (NRS) — an innovative, energy-efficient gas separation technology designed to optimize natural gas processing. Operating at ambient temperatures and capable of remote monitoring and control, the NRS System offers a simplified and economically attractive approach to maximizing natural gas liquids (NGL) recovery and enhancing compressor station performance. This solution enables the production of pipeline-quality lean gas (<1,100 BTU/scf HHV) at virtually any location, significantly reducing volatile organic compound (VOC) emissions. Its robust design supports high mechanical availability and operational efficiency, making it particularly valuable for gas gathering and compression applications in remote or distributed environments. Since its commissioning in December 2023, the NRS pilot has consistently delivered target lean gas quality with over 99% mechanical availability. Remote operations commenced in May 2024, demonstrating the system's reliability and scalability. At a pilot site processing gas with an inlet energy content of approximately 1,305 BTU/scf, the system is projected to recover over $1.1 million in annual NGL value for a 7,500 HP compressor station. This technology represents a significant advancement in natural gas separation, offering a scalable, low-emission, and high-value solution for the energy sector.
