Factors That Affect the Design of a Selective Catalytic Reduction System

Owners of industrial plants may use an SCR (selective catalytic reduction) system to reduce the volume of noxious gases, such as nitrogen oxide, that are released from the exhausts of their fuel systems. However, many factors must be considered before an effective SCR system can be designed for your industrial plant. This article discusses some of those factors. Use this information to help you to select an experienced firm to design your SCR so that you avoid being prosecuted for air pollution at your industrial plant.

Extent of Gas Pollutants

The experts may be interested in measuring the volume of gaseous pollutants that your industrial processes produce. That information will enable the SCR designer to determine how much catalyst, such as ammonia gas, should be mixed into the exhaust gas that needs to be treated. The catalyst then reacts with the pollutants so that they can be converted to less harmful substances, such as water and nitrogen gas.

Operational Temperatures

Another key factor that may have to be considered when designing your gas treatment system is the temperature at which your industrial equipment operates. Temperature is important because it can accelerate or decelerate the rate at which chemical reactions can take place during the gas treatment process. The SCR system may then have a component that raises the temperature of the exhaust gases in case your industrial processes do not cause the exhaust gas to be released at a temperature that favours the activation of the chemical reactions that can treat that gas.

Types of Solid Contaminants

The efficient operation of an SCR system may also be affected by the types of solid pollutants, such as dust, present in the exhaust gases. Those solid pollutants can cause the SCR system to become clogged quickly. The designer measures the volume of those solid pollutants so that he or she can recommend appropriate measures, such as the use of soot-blowers, to prevent the gas treatment system from failing prematurely.

As you can see, your operating conditions need to be studied carefully before a gas cleaning system can be designed for your plant. Do your part in this process by availing relevant information to the design team. You should also grant them unfettered access to your plant so that they can gather the additional information needed to design the most effective gas treatment system for your specific application. Only then will you be sure that your employees and the environment are safe from the noxious fumes generated by your equipment.
