Gas treatment capacity: 1 - 5000 Nm³/h
During the use of gases, gases of ordinary purity are obtained through a certain process. However, in actual applications, high-purity or even ultra-high-purity gases are required. At this time, it is necessary to further purify the gas after air separation. Our company, combines years of R&D and production experience to provide various high-purity gas purification devices, such as nitrogen purification devices, hydrogen purification devices, argon purification devices and other high-purity gas purification devices, to meet the industrial needs of users for high-purity and ultra-high-purity gases.
According to practical applications, the nitrogen purification device is divided into hydrogen deoxygenation type nitrogen purification and carbon deoxygenation type nitrogen purification device.
Hydrogen Deoxygenation Type Nitrogen Purification
The NCH hydrogen addition and deoxygenation series nitrogen purification device adds a certain amount of hydrogen to ordinary nitrogen. After mixing, the nitrogen-hydrogen mixture gas reacts in the deoxidizer filled with palladium catalyst, that is, O2 + 2H2 → 2H2O. Then, water is removed through condensation, and the nitrogen is dried and adsorbed to obtain high-purity nitrogen.
This device is mainly composed of a mixer, a pre-heater, a deoxidizer, a cooler, a refrigeration dryer, a dryer, various control systems, etc.
Nitrogen purification by hydrogen deoxygenation with trace amounts of hydrogen is especially suitable for the metal heat treatment industry.
