Nitrogen - generator, its use, as well as a process for the in situ production of nitrogen

摘要

An inventive nitrogen generator to the in situ preparation and to store up to the consumption of compressed, pure, highly pure 5.0 or ultra-pure nitrogen, comprising connected to one another in the direction of flow of the nitrogena) means for the production of nitrogen from compressed air;b) for compressing the compression means on the nitrogen produced in a) to a pressure within the range of greater than 10 to about 400 bar; andc) means for storing of the in b) compressed nitrogen;is characterized in thatupstream of the means for storing means to the - and / or diversion of the compressed nitrogen are provided, which it for a certain free preselectable or controllable period prevent that, in the compressed nitrogen is passed to means for storing.A corresponding method for the production of nitrogen is characterized in that during starting or turning on of the previously described nitrogen generator, particularly preferably of a psa (l) - system, the in step b) of the method according to the compressed nitrogen for a certain free preselectable or controllable time - or, so that it not for the said period of time in the means for storing is passed.The generated pure, high purity or ultrapure nitrogen is of a constant, high purity and, as the inert gas, advantageously for laser cutting applications or used in the food industry.
