TLC type nitrogen and carbon purification device Product introduction

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.
