PHASE ONE PHASE TWO PHASE THREE
COMBUSTION EFFICIENCY
Emissions of key pollutants , including NOx , SOx , carbon monoxide ( CO ) and carbon dioxide ( CO 2 ), can be reduced by controlling this important process reaction . Accurate measurements of oxygen ( O 2 ) and combustibles ( COe ) in the reaction mixture allow the optimum ratio between fuel and air to be achieved , lowering fuel consumption , and improving safety .
GAS CLEANING
A range of processes are available to safely remove harmful substances from process gases that might otherwise be emitted by the plant . Typical examples include DeNOx treatments ( i . e . ammonia slip processes ) and flue gas desulfurization . A variety of gas measurements are required depending on the gas cleaning process being used .
EMISSIONS MONITORING
By measuring pollutants within the flue gas , plant operators can determine process efficiency , protect the environment , and demonstrate that they are compliant with regulations . Continuous monitoring is required to measure all the necessary components of the flue gas , including criterion pollutants and greenhouse gases .
