Product Description
In SCR De-NOx system, NOx contained in many kinds of exhaust gas is reduced by ammonia (NH3), urea [(NH2)2CO], etc. Called "Ammonia like material" to nitrogen (N2) and water (H2O).
The most suitable reducing agent can be selected out of ammonia like materials based on economics, handling and safety.
SCR DeNOx system is mainly consisted of reactor, reductant tank/storage, reductant injection system and catalyst. After injection and completely mixing of reducing agent at the inlet of reactor, the exhaust gas is led into catalyst bed where the NOx removing reaction will take place.
Application: (Gas, Oil, Coal fuel) Boiler, Gas turbine (HRSG), Waste to Energy plants and Diesel engines
Efficiency: More than 90% of De-NOx Ratio
Operation Temp.: 200-420º C
NOx Concentration: 10-2, 000 ppm
Pressure Drop: Less than 1.2 kPa/reactor
Reactor: Catalyst bed can be installed in heat recovery boiler
Operation: Steady state can be achieved within 30 minutes from cold start
1) When De-NOx efficiency is required more than 95%, the emission of excess reducing agent will be increased distinctly.
2) Operation temperature should be determined by considering SOx concentration contained in exhaust gas to avoid formation of ABS, resulting in clogging the catalyst.
The Res. Inst of Chem. Mach of the Ministry of Chemical Industry was founded in Beijing in 1958, and moved to Lanzhou in 1965.
The Res. Inst of Automation of the Ministry of Chemical Industry was founded in Lanzhou in 1963.
In 1997, the Res. Inst. Of Chem. Mach of the Ministry of Chemical Industry and the Res. Inst. Of Automation of the Ministry of Chemical Industry were combined to become the Res. Inst of Chemical Machinery and Automation of the Ministry of Chemical Industry.
In 2000, the Res. Inst of Chemical Machinery and Automation of the Ministry of ChemicalIndustry completed its transformation to enterprise and registered as Tianhua Instituteof Chemical Machinery and Automation.
Tianhua Institute has the following subordinated institutions:
Supervision and Inspection Center of the Quality of Chemical Equipments in Nanjing, Jiangsu Province

The Lanzhou United Institute of Chemical Machinery and automation and the Nanjing United Institute of Petrochemical Industry Furnaces were founded by Tianhua Institute and the Sinopec.
Tianhua Institute has an occupation area of 80 000m2 and a total asset of 1 407 000 000 Yuan (RMB). The annual output value is 1 000 000 000 Yuan (RMB).
Tianhua Institute has about 916 employees, 75% of them are professional personnel. Among them are 23 professors, 249senior engineers, 226 engineers. 29 professors and senior engineers enjoy national special subsidy, On 5 people the title of Middle-aged and Young Specialist with Outstanding Contribution to the P. R. China are conferred
