The reagent mixes with the flue gas and both components enter a reactor chamber containing the catalyst. As the hot flue gas and reagent diffuse through the catalyst and contact activated catalyst sites, NO x in the flue gas chemically reduces to nitrogen and water.

The heat of the flue gas. optimum temperature range depends on the type of catalyst used and the flue gas composition. Optimum temperatures vary from °F to °F (°C to °C) (ICAC, ). Typical SCR systems tolerate temperature fluctuations of ± °F (± 90°C) (EPA, ).

Continuous emission monitoring (CEM) is a rapidly growing market worldwide [1]. The combustion of oil, coal and natural gas is still the most important energy source for power generation.

In the exhaust gas of these power facilities the content of SO2, NO and NO2 is significant, so that exhaust gas treatment and reduction is necessary. Serinus 50 SO 2 Analyser. The Serinus 50 Sulfur Dioxide (SO 2) analyser delivers precise and reliable performance at excellent uses proven pulsed UV fluorescent radiation technology to measure SO 2 in ambient air (LDL monitoring.

Geosyntec was already in the process of developing specialized continuous real-time measurement methods for certain flue gas constituents important to electric utilities (such as SO 3, ammonia, and various halogens), in addition to the nitrogen oxide, sulfur dioxide, and other combustion byproducts typically present in flue gas exhaust.

Our O2 analyzer is of the long-life electrochemical "fuel cell" type. This sensor produces a small millivoltage output that is directly proportional to the oxygen detected. This output is then amplified and displayed on a digital readout meter and is also available as an output to your site data recorder.

Scrubber systems rely on a chemical reaction with a sorbent to remove a wide range of pollutants, including sulfur dioxide (SO2), acid gases, and air toxics, from flue gases.

When used to remove or "scrub" SO2 from the flue gas, these devices are commonly called flue gas desulfurization (FGD) or scrubber systems. the sample gas stream without removal of the pollutants of interest.

In particular, NO 2, due to its high solubility in water, is more susceptible to scrubbing than, for example, NO or CO. The District recommends a gas sampling system which can be used universally.

The set. Commercial respirometers are capable of continuously and automatically measuring oxygen uptake in bioreactors. A method for continuously and automatically measuring carbon dioxide evolution can be retrofitted to commercial respirometers.

Continuous emission monitoring (CEM) is a rapidly growing market worldwide [1]. The combustion of oil, coal and natural gas is still the most important energy source for power generation.

In the exhaust gas of these power facilities the content of SO2, NO and NO2 is significant, so that exhaust gas treatment and reduction is necessary. The other is to install cleaning equipment – a scrubber. A scrubber is very cost-effective, but regulations necessitate the monitoring of the SO 2 and CO 2 content of the flue gas in order to ascertain that the scrubber is functioning correctly.

To do this, the best solution is to have an OPSIS System.

The monitoring system is an extractive type that employs an air aspirator to pull a sample through a probe and sample conditioning assembly. The gas sample flows through an analyzer that contains an electrochemical cell as the sensing element. The pressure compensation deals with changes in barometric and flue gas pressure.

In addition, if the certified test gas applied for calibration causes a pressure increase, pressure compensation would remove the effect. Summary. Selection of the Continous Emission Monitoring system will depend largely on the application.
