System for obtaining high purity nitrogen in nitrogen gas purification applications and a method thereof

A system for nitrogen gas purification applications, the system comprising:

• a nitrogen inlet port, which allows connection to a nitrogen generator to receive nitrogen gas,
• a catalyst tank containing at least one catalyst, which allows eliminating of oxygen molecules in the nitrogen gas,
• a hydrogen inlet port for the inlet of hydrogen gas into the catalyst tank,
• at least one solenoid valve for controlling the flow of hydrogen gas entering the catalyst tank, and closing the inlet of hydrogen gas to the system,
• a hydrogen flowmeter for monitoring the flow of hydrogen gas,
• at least one proportional valve that allows passing of the hydrogen gas at a pre-determined flow rate,
• a control unit for setting the pre-determined flow rate of the hydrogen gas and controlling a temperature of the hydrogen gas,
• a first cooler (aftercooler) that condenses water therein by cooling nitrogen gas,
• a water separator for separating the condensed water formed in the nitrogen gas,
• at least one discharge member and at least one discharge port for discharging the water separated by the water separator,
• a refrigerant-type dryer unit comprising an exchanger for heating and cooling the nitrogen gas, a compressor for compressing refrigerant gas and a thermostatic expansion valve for cooling a resulting condensed refrigerant fluid by reducing its-pressure of the resulting condensed refrigerant fluid,
• at least one temperature sensor for controlling a temperature of the system,
• a control system panel for controlling the system, and
• a nitrogen outlet port for releasing obtained nitrogen gas from the system.
