Process principle：

At a certain temperature, the residual oxygen in nitrogen reacts with carbon catalyst to produce carbon dioxide. The chemical reaction formula is C+02=C02, so that the oxygen content in nitrogen is <5ppm,. The C02 and water are removed by pressure swing adsorption process, and the particulate impurities in nitrogen are removed by fine filter. The purity of nitrogen is more than 99.9995%.The catalyst for the combustion type nitrogen purification unit is expendable, and the device needs to be added after running for a period of time. It is characterized by no need of hydrogen source and no hydrogen in the outlet nitrogen. The device needs to configure nitrogen for 1.1 times according to the nitrogen output, and the purity of the raw nitrogen is generally ≥ 99.9%-99.99%。

 TLCA type is a single deoxidization tower process. Users need to stop when adding catalyst. It is suitable for continuous and discontinuous use of users.

TLCB type is a double deoxidizer process, users do not need to stop when adding catalyst, can add catalyst under the condition of continuous operation of equipment, suitable for continuous and uninterrupted use of users.

This process is especially suitable for aluminum profile smelting, bearing, chemical industry, electronics, metal materials, precious metal refining, hydrogen Limited places and other industries.

2. Nitrogen does not contain hydrogen, and is suitable for places where hydrogen and oxygen are strictly required.

3. Deaerator and heater adopts high temperature resistant material, safe and reliable.

4. The preheater added in the device can recover the heat of nitrogen after deoxidization in the deoxidizer and save more than 30% of energy consumption.

5. Adsorption dryer is used to remove CO2 and dehydrate deeply. It has large adsorption capacity, long adsorption time and low energy consumption.

6. Dry machine adopts imported PLC control, safe and reliable.

7. A double deoxidizer with one structure can be used to add carbon catalyst in the case of continuous use, so as to meet the continuous non-stop use of users.

8. The heater is designed with one and one spare parts to ensure the heating temperature and improve the reliability.

9. Carbon catalyst can be directly added to the deoxidizer without impurity and carbon powder residue after use. Automatic interlocking emptying, multiple fault alarm.
