ColdStream Energy, LLC is on stage in San Antonio for a panel discussion at the GPA Midstream Convention on Monday, Sept. 21, 2026.

Introducing MaCH₄™ NGL Recovery Solution (NRS). ColdStream Energy (CSE) has developed a field proven, robust, and energy efficient gas separation technology utilizing Pressure Swing Adsorption (PSA) for natural gas processing. This technology operates independent of process temperature or ambient temperature and is designed for unattended operations to be remotely controlled or monitored. It is a simple and economically compelling solution for maximizing NGL value for producers and gatherers, while also maximizing the efficiency and runtime of engines and respective compressors. The ability to produce pipeline quality, < 1,100 BTU/scf (HHV), lean gas at any location ensures the lowest VOC emissions possible, even when remotely located. This is an innovative and valuable solution for the energy industry with wide applicability, and especially relevant to gas gathering and compression stations. The advantages of the MaCH₄™ NGL Recovery Solution (NRS) technology to other natural gas separation technologies are: ▸ Simple process for unattended operations that can be remotely monitored and controlled ▸ Low maintenance with minimal operator intervention, over 99% mechanical availability ▸ Large 10:1 turndown ratio ▸ Handles BTU swings from fluctuating feed gas compositions ▸ Cryogenic-like recovery of NGLs without the low temperature requirements (no freeze issues) ▸ Minimal power requirements (single phase), especially compared to cryogenic processes ▸ Recovered heavy hydrocarbons remain in gaseous form (no liquids, no product storage tanks required) ▸ Requires no chemical consumables to operate (i.e. methanol, glycol, lubricating oil) ▸ Skid mounted and field transportable ▸ Dehydrates the saturated feed gas and recovers heavy hydrocarbons in a single step process
