SYC nitrogen plus carbon purification plant

Product introduction

At a certain temperature, the residual oxygen in nitrogen reacts with the carbon catalyst to form carbon dioxide. The chemical reaction formula is C+O2=CO2, and the oxygen content in nitrogen is ≤5PPM. After the pressure changing adsorption process, CO2 and water are removed, and the particles and impurities in nitrogen are removed by filtration, the purity of nitrogen above 99.9995% is obtained. The catalyst of the combustion nitrogen purification device is consumable, which needs to be added after the device has been running for a period of time. The biggest feature of the device is that it does not need to be equipped with a hydrogen source and the outlet nitrogen does not contain hydrogen. The device needs to be equipped with raw nitrogen according to 1.1 times of the nitrogen output. Syc-a is A single deoxidizing tower process, the user needs to add catalyst when the appropriate downtime, suitable for continuous intermittent use of the user. Syc-b is a double deoxidized tower process, the user does not need to stop when adding catalyst, can be added under the condition of continuous operation of equipment, suitable for continuous continuous use of users.


Technical characteristics

◆ high efficiency carbon catalyst, advanced technology, good stability, high purity nitrogen.

◆ nitrogen does not contain hydrogen. It is suitable for places with strict requirements on hydrogen and oxygen.

Deoxidizer and heater adopt high temperature resistant material. Safe and reliable.

◆ the preheater added in the device can recover the heat of deoxidized nitrogen in the deoxidizing device, and can save energy by more than 30%.

◆ adsorption dryer for CO2 removal and deep dehydration, large adsorption capacity, long adsorption time, low energy consumption.

◆ the suction dryer adopts PLC control imported from Germany Siemens, which is safe and reliable.

◆ the structure of the dideoxy tower is one in use and one in reserve. The catalyst can be added in the case of continuous use to meet the continuous non-stop use of customers.

◆ the heater adopts a one - in - one - off design to ensure the heating temperature and improve the reliability.

◆ after using the carbon catalyst in the deoxidized tower, there are no impurities and carbon powder residue, no need to purge, carbon catalyst can be added directly.

◆ equipped with automatic chain vent, a variety of fault alarm.
