Mixed with water, sand and gravel, the cement forms concrete which has almost unlimited usage areas within the construction industry.ENVIRONMENTAL ASPECTS The processing of raw materials generates very high levels of dust, and the fuel used for the heating as well as the raw material itself give rise to a variety of gaseous air pollutants, NOX and SO2, and sometimes also other ...

How it works In the combustion process nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). ...
In power plants and various other combustion processes waste NOx reduction, referred to as deNOx, is typically achieved by selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR). In SCR process, Ammonia (NH3) is injected into the gas flow from the combustion process; this reacts with NOx in the flue gas, ...
Moreover, the limits of each technology in terms of dust loading levels, process temperatures, stack diameters, etc also need to be taken into account. ...

Many industrial processes utilize the combustion of natural gas, oil, or coal. However, the combustion of these fossil fuels produces nitrogen oxide or NOx, which contributes to smog and air pollution. ...
As a cost effective heated analyzer, the MIR 9000H is also an ideal solution for process control to monitor ammonia slips in SCR/SNCR processes. In these processes, either ammonia or urea can be used. ...

This paper presents the results of computational kinetic modelling of the removal of nitrogen oxides (NOx) from flue gases by selective non-catalytic reduction (SNCR) process using urea as a reducing agent. CHEMKIN and SENKIN computer codes were used with latest reaction mechanism parameters for simulated conditions in an isothermal plug flow reactor. ...
