Carbon Carried Purification to Nitrogen
Carbon-carried purification can be used for processes that are sensitive to hydrogen or have difficulties in hydrogen gas source. Raw nitrogen reacts with excess carbon at high temperature to produce CO2. High purity nitrogen can be obtained after passing through the adsorption tower of decarburized oxygen compounds.
The chemical equation is: C + O2 = CO2 + Heat
In order to reduce the replacement frequency and operation cost of carbon fiber, and improve the utilization rate of equipment, generally it is designed to be replaced in 3 or 6 months, and the recommended crude nitrogen purity is 99.9%. Under this purity condition, the power consumption of supporting air compressor and carbon fiber consumption can be taken into account to achieve the economic operation.
The carbon-carrier purification is composed of heater, reaction tower, water cooler, CO2 removal adsorption tower, oxygen separator, flow meter and product nitrogen buffer tank.
Especially suitable for the places with restrictions on hydrogen, such like aluminum profile smelting and processing, bearing, chemical industry, electronics, metal materials and precious metal refining.
☆ Use the high efficiency carbon catalyst with advanced process and good stability to obtain the high nitrogen purity.
☆ Nitrogen does not contain hydrogen for the strict requirement places of hydrogen and oxygen.
☆ The deaeration tower and heater are made of high temperature resistant materials, which are safe and reliable.
☆ Carbon catalyst can be added directly to the deaeration tower. There is no impurity and carbon powder residue after using, and no need to purge.
☆ Automatic interlocking venting and multiple fault alarms.
