摘要：
A method for production of nitrogen for application at high pressure, preferably for pressure injection in submarine or substerranean oil or natural gas wells, by combination of natural gas in air, which is compressed prior to the combustion, for binding of the oxygen content of the air in carbon dioxide to be removed from the flue gas by absorption, whereas the remaining nitrogen is pressurized to a predetermined high pressure suitable for such application.
