1、Technology Description
There are two main denitration methods (1) Selective Catalytic Reduction (SCR) technology and (2) Selective Non-Capital Reduction (SNCR) technology.
SCR technology has the characteristics of technical maturity, high efficiency, stable operation, no secondary pollution, etc., when the denitration efficiency requirement exceeds 70%, SCR technology is generally used. SCR technology provides denitration efficiency of more than 90%.
The denitration efficiency of SNCR technology on coal pulverized kiln is usually 40 to 50%, on circulating fluidized bed 50 to 70%, it is mainly used in small boilers and circulating fluidized bed boilers. SNCR technology does not require a catalyst, but requires completion of the denitration reaction in a temperature range of 800 to 1100 °C.

Wet CO2 removal technology
Wet method decarbonization technology is a low energy consumption technology that is widely used to remove CO2 and H2S from synthetic ammonia, methanol feed gas, refinery gas, urban coal gas and natural gas.
Hydrogen production by conversion of light hydrocarbons with steam
The production of hydrogen from natural gas consists of two parts: the conversion of gas vapor into converted gas and the purification of hydrogen using the PSA method. After compression and desulfurization, natural gas is mixed with water vapor. Under the action of nickel catalyst at a temperature of 750~850℃, natural gas is converted into converted gas consisting of hydrogen, carbon monoxide and carbon dioxide. The converted gas can be further converted into hydrogen and carbon dioxide by conversion technology, then the converted gas or reformed gas is purified and separated by PSA method to produce high purity hydrogen.
Desulfurization technology using the redox wet method
HDS cyanogen desulfurization and removal technology is a wet oxidation method, which is a distinctive desulfurization method developed by Huaxi and scientific and technical personnel in the synthetic ammonia and coke industry, which allows the desulfurization percentage of H2S in gas to be at least 99.9%, and the desulfurization percentage of HCN to be more than 97%.
Flue gas desulfurization technology using ammonia
A by-product of desulfurization using the ammonia method is ammonium sulfate fertilizer; from 1 ton of ammonia you can get 4 tons of by-product ammonium sulfate, and its profitability depends on the prices of ammonium sulfate and ammonia.
Hydrogen production from coke oven gases
Coke oven gas has the characteristics of large gas volume, low pressure, complex impurity content and low hydrogen content. In addition to being used to generate electricity, hydrogen can be recovered for use in chemical plants such as coal tar hydrogenation plants, glycol plants and synthetic ammonia plants. High purity hydrogen gas is obtained from coke oven gas through compression, purification, conversion, PSA, etc. units. Through process integration, it is also possible to simultaneously produce CO, hydrogen and LNG products.
Vinyl chloride recycling technology
