Due to the disadvantages long-term existing in feed gases of chemical industry, such as large humidity, high pressure, high space velocity and wire speed, severely lack of oxygen and more and more higher purification demand, Zhongyuan Institute of Chemical purification and us together research and developed the XYF-2 granular iron oxide desulfurizer.
1,High desulfurization precision: inlet H2S: 100mg/Nm3, outlet: 0.5mg/Nm3.
2,Large sulfur capacity: 8%-10% for one time.
3,High strength and good water resistance ability: not change to mud under the condition of boiling for 15 minutes or soaking for long time in normal temperature water; after drying, the activation and strength not change.
Product Specification / Models
1.Saturation sulfur capacity(mg/g): 500min(Under normal temperature, original particle)
2.Filling density(kg/L): 0.7u00b10.05t
3.Water contentt(%): 45mint
4.Desulfurization precision(PPm): 0.5max(Inlet: sulfur content below 100mg/Nm3)
5.Radial pressure strength(N/cm): 40mint
7.Particle size(mm): Diameter(3.5~5)u00d7L(5~15)t
8.Water resistance strength: Not naturally broken and change to mud under the condition of soaking.
Application / Models
The desulfurization is widely used for shift gas desulfurization in chemical fertilizer industry, and the desulfurization and purification of natural gas, H2 feed gas, synthetic ammonia N2, and Urea CO2 gas.
Desulfurization and regeneration theory:
Fe2O3-XH2O+3H2S== Fe2S3-XH2O+3H2O(desulfurization chemical formula)
Fe2S3-XH2O+3/2O2== Fe2O3-XH2O+3S(regeneration chemical formula)
The H2S reacts with the activated iron oxide in desulfurizer and produce sulphide. Then the sulphide reacts with oxygen in feed gas and produce elemental sulfur which will deposit in the micro-pore of desulfurizer thus making the desulfurizer regenerate and reaching to the goal of desulfurization.
