If the flue gas is cooled sufficiently, condensation will occur and liquid will appear on surfaces at temperatures below the dew point. The liquid phase will contain highly corrosive sulfuric acid. This causes sulfuric acid corrosion, so called low-temperature corrosion.
Exhaust gas treatment equipment uses different technologies to protect the environment and purify the air by recycling or reducing the harmful Common exhaust gas treatments include soot exhaust gas treatment, dust exhaust gas treatment, organic waste gas treatment, exhaust gas odor
All Pumps Marine Chemicals Air Tools Workshop Equipment Cleaning Equipment Gases, refrigerants and cylinders Refrigeration equipment Welding Environmental Ropes. Exhaust Gas Treatment. Our Solutions. Soot and Corrosion inhibition. Applications of Raman scattering in the characterization of materials used in the catalytic treatment of exhaust gases, both from vehicles and stationary sources, are reviewed.

This calcium oxide is obtained by baking particulate calcium carbonate, and exhaust gas discharged from a semiconductor production device is removed of harmful gas components by allowing the exhaust gas to contact and react with this exhaust gas treatment agent while in the gaseous state.
For an efficient Flue Gas Desulfurization (FGD), Omya special Calcium Carbonates such as Desulfocarb, Desulfonit, Reasorb and Epsical help to increase process and cost efficiency in FGD. Omya also offers different types and grades of natural mineral products as well as selected
Pure gas, sure gas – With almost 50 years of experience, BASF offers its customers efficient solutions for the treatment of various gases such as natural gas, synthesis gas, and biogas.
[8] The combustion exhaust gas treatment method according to [7], further including a step of adding heat The flue gas treatment system or flue gas treatment method of the present invention has a high degree of freedom in plant design, and has high thermal efficiency and CO 2 removal capability.
The Exhaust Gas Recirculation (EGR) system’s purpose is to reduce NOx emissions that contribute to air pollution. The first EGR systems were added to engines in 1973, and today most engines have an EGR system. As long as the EGR system is functioning properly, it should have no noticeable effect
System components for exhaust-gas treatment with double injection. The chemical reaction equations of the exhaust-gas treatment are modelled in the form of differential equations in the control unit, and they are used to determine an improved ammonia filling level for each catalytic converter.
Exhaust gas treatment technology. Download PDF. 7 downloads 15 Views 3MB Size Report. One of the main problems is gasoline direct injection exhaust treatment. The mixture of modes of stratified lean and homogeneous mix a large amount of nitrogen oxides, the three-way catalyst is not able to
Exhaust gas recirculation (EGR) is currently the most important NOx emission control system. During the last few years the EGR rate has increased progressively as pollutant emission regulations have become more restrictive.

Exhaust gases are retained in the charge both passively (i.e., through incomplete scavenging of the fresh charge) or through active recirculation via an As a result, one of the most significant automotive engine sensors in use today is the exhaust gas oxygen (EGO) sensor. This sensor is often called a
