Integrated EPC Solutions for Nitrogen Rejection Facilities
Saulsbury delivers specialized engineering, procurement, construction, and fabrication services for Nitrogen Rejection Units (NRUs), helping natural gas producers maximize product value, meet pipeline specifications, and optimize plant performance.
Proven Expertise in Nitrogen Rejection
As natural gas production expands into reservoirs with elevated nitrogen concentrations, Nitrogen Rejection Units (NRUs) play a critical role in processing gas to meet transmission pipeline specifications and maximize hydrocarbon recovery. Successful NRU projects require specialized engineering, careful process integration, and experienced project execution.
Saulsbury has extensive experience delivering nitrogen rejection facilities for a wide range of gas processing applications. Working closely with leading NRU technology providers and package suppliers, our multidisciplinary teams provide complete EPC solutions that optimize plant performance while integrating seamlessly with upstream and downstream processing systems.
Whether supporting a new gas processing facility, expanding existing operations, or relocating and refurbishing processing assets, Saulsbury delivers practical, constructible solutions that improve efficiency, reduce project risk, and maximize long-term operational reliability.
Experience Across Nitrogen Rejection Facilities
Saulsbury has completed numerous nitrogen rejection projects ranging from small conventional gas processing applications to large cryogenic facilities. Our experience includes integrating NRUs into new and existing gas processing plants while supporting complex balance-of-plant systems and utility infrastructure. Projects have included installations across Texas, North Dakota, Alabama, and Wyoming with facilities ranging from approximately 4 MMSCFD to 50 MMSCFD and beyond.
