Cemgas 5000 SO2/SO3 Laser Analyzer


The CEMGAS 5000 SO2/SO3 Laser Analyzer is a complete pre-calibrated multi-component laser infrared (IR) spectrometer for continuous emissions monitoring analysis.  The LaserCEM utilizes patented OFCEAS IR laser technology for enhanced specificity, selectivity, accuracy and stability.


Reliable, robust and easy-to-use this analyzer is the optimal solution for the analysis of SO2 and SO3.  It’s patented low-pressure sampling system enables low-cost installation and reduced maintenance.  




Why choose the CEMGAS SO2/SO3 Analyzer?

Not only does this analyzer allow the operator to closely monitor the gases but it is highly durable to harsh process conditions and provides measurements with extremely high spectral resolution.

In addition to the exclusive and powerful sampling method (no heated line nor treatment of samples) it provides interference-free, fast and sensitive analysis, regardless of the matrix of the gas to be analysed.

Compliant to standard EN 15267-3 : 2008 and QAL 1 de EN 14181 the Cemgas 5000 SO2/SO3 laser analyzer comes pre-calibrated for your CEM’s application and includes a touch screen interface and on-board PC for local/remote control and real time display/recording of the results.

What are SO2 and SO3 and why do they need to be measured?

Sulfur dioxide (SO2) is a highly reactive gas and is toxic in large amounts. A major air pollutant, SO2 is one of primary causes of acid rain and is the precursor to sulphur trioxide (SO3) and sulfuric acid (H2SO4). These two biproducts of the SO2 reactions are more corrosive than SO2. By not monitoring their levels, the damage that can occur to internal process components will cause increases in costs and may create unscheduled or unplanned outages.

An example of this occurance can be observed in coal fired power plants utilizing high sulphur coals. Burning high sulphur coals generates a large amount of SO2, which in turn can lead to the production of SO3. With the addition of post combustion processes for the removal of NOx, this can also increase the SO3 levels in the flue gas. Documented issues resulting from the SO3 production inclue the "blue plume" effect, corrosion, and contamination of downstream components due to the formation of salts when ammonia injection is utilized.

Having a continuous and precise knowledge of the SO2 / SO3 couple enables an operator to choose the controlling conditions in order to limit the formation of SO3 and its indirect costs.
