FIELD: process engineering.SUBSTANCE: in compliance with one version, nitrogen regeneration system comprises tank for multistage separation to extract nitrogen from cooled flow of natural gas. At least, a portion of obtained flow containing nitrogen escaping the tank for multistage separation can be used as a coolant and processed at nitrogen regeneration plant and/or used as a fuel gas for natural gas liquefaction plant.EFFECT: higher efficiency of separation.34 cl, 4 dwg |
