Nitrogen Rejection Units

Nitrogen rejection from natural gas is necessary of about 17% of US gas reserves according to GRI. Cryogenic separation and pressure swing adsorption have been employed to remove nitrogen from natural gas. Sep-Pro designs and builds a wide range of natural gas processing equipment. NRU equipment is part of this. Pressure swing adsorption needs to be combined with dehydration and hydrocarbon dew point control. Nitrogen rejection is a difficult technical separation. Coal bed methane has carbon dioxide (CO2) and nitrogen rejection requirements. High nitrogen gas can’t be pipelined realistically if greater than 4%.
            Sep-Pro leases or sells NRU equipment ranging from 300MSCFD to 5MMSCFD feed with nitrogen from 6-to 30 vol% High nitrogen gas is a worldwide problem. Stranded high nitrogen gas is a real bad problem.  Sep-Pro would lease NRU equipment and LPG equipment internationally and domestically. Molecular sieves and cryogenic equipment are within Sep-Pro’s scope as is gas to liquids (GTL): Sep-Pro has numerous stranded gas solutions.
            Natural gas processing equipment requires a wide range of engineering and manufacturing capability. Nitrogen rejection units (NRU) require a different technical approach than LPG or natural gas liquids recovery (NGL). Sep-Pro has built both. Pressure swing adsorption (PSA) is used for gas dehydration, carbon dioxide (CO2) removed, nitrogen rejection (NRU), hydrocarbon dew point control.
            Leasing is an option for almost all of Sep-Pro’s natural gas processing equipment. NRU equipment leasing is attractive because it minimizes the producer’s risk on gas that has actually zero value. Worldwide high nitrogen gas is a major problem. To generate electrical power with it requires a power grid, which is usually lacking. Sep-Pro will solve your nitrogen rejection problem with the technical approach that is appropriate.
