Functions and characteristics of 888 desulfurization catalyst ◆ strong desulfurization capacity
In the desulfurization of gas containing 4-7g / Nm3 H2S, the desulfurization efficiency reaches 99
5%
When the H2S content in coke oven gas is more than 4G / Nm3, it can meet the process requirements after desulfurization
When the H2S content in semi water gas is more than 3
5g/nm3, the outlet can be reduced to less than 50mg / Nm3
◆ comprehensive desulfurization
It can remove both inorganic sulfur and a certain amount of organic sulfur, and the maximum organic sulfur removal efficiency is more than 80% (mainly COS)
◆ under the same working conditions, the capacity of desulfurization unit can be increased by more than 20% by using 888 desulfurization catalyst
◆ do not block the tower with sulfur
During regeneration, the flotation sulfur particles are large, the solution viscosity is low, and the sulfur particles are easy to separate; 888 desulfurization liquid has strong self-cleaning ability and can wash the tower at the same time of desulfurization
◆ low cost
Under the condition of the same load, the desulfurization cost is greatly reduced by replacing other catalysts with 888 desulfurization catalyst
◆ in the process of production and operation, it can effectively inhibit the side reaction, so as to reduce the generation of side salt and greatly reduce the times of discharging and replacing solution
◆ 888 desulfurization catalyst does not need to add other cocatalysts
The pre activation process is simple and the time is short
Whether ammonia or soda ash is used as absorbent, it can maintain stable desulfurization efficiency
◆ the suspended sulfur content of desulfurization lean solution of 888 method is low
Generally, it can be reduced to less than 0
3g/l
A clear solution is conducive to reducing the resistance of the desulfurization system
When the suspended sulfur is high due to the use of other desulfurization catalysts, it can be quickly reduced by using 888 desulfurization catalyst
◆ 888 desulfurization solution has good selectivity for H2S
When the CO2 / H2S in the gas is high, it can also remove H2S to the specified control index
Based on this characteristic, 888 desulfurization catalyst can also be applied to the tail gas treatment of low-temperature methanol washing process, and the treated tail gas can be discharged up to the standard
◆ under the action of 888 desulfurization catalyst, there is polysulfide reaction, and elemental sulfur is precipitated during catalytic oxidation and separated during regeneration, which can inhibit and eliminate sulfur accumulation and block pipeline and equipment filler
◆ desulfurization catalyst has high activity, low consumption, economic operation and convenient use
When 888 desulfurization catalyst is used for desulfurization of the old system, there is no need to stop and discharge the original desulfurization liquid, which can reduce environmental pollution
