The gas purification equipment is used for further deoxygenation and drying of the product gas generated. The purification equipment is especially suitable for heat treatment processes that need high purity nitrogen and hydrogen to increase the brightness of the final products. Our gas purification equipment is usually used together with PSA nitrogen generator. The equipment specifications can be customized according to the usage cases and generation equipment purchased to better support your production.
It is needed when producing nitrogen with a high purity up to 99.9995%

How Gas Purification Works
When nitrogen and hydrogen flow into the gas purification equipment and fully mixed, it enters the deoxidizer device and the chemical reaction of 2H2+O2=2H2O happens under catalyst. After deoxygenation, the nitrogen will enter the cooler to remove the moisture, then enters dryer A and dryer B to lower the dew point of the nitrogen gas to a degree lower than -60℃. When one dryer is undergoing the adsorption and drying process, the other will release the adsorbed moisture into atmosphere to make space for another adsorption process. After filtered to remove dust, the remaining gas will be the product, i.e. high purity nitrogen. |
