Isokinetic Stack Sampling
Isokinetic stack sampling is a method used to measure the concentration of pollutants in exhaust gases emitted from industrial stacks, ensuring compliance with environmental regulations. The process involves drawing a representative sample of the flue gas at the same velocity as the gas flow in the stack, which is referred to as “isokinetic” sampling. This ensures that the sample collected accurately reflects the characteristics of the gas stream without altering its composition. The collected sample is then analyzed for various pollutants such as particulate matter, sulfur oxides, nitrogen oxides, and other toxic emissions.
This sampling technique is particularly important for regulatory compliance, as it provides reliable data for assessing the performance of air pollution control systems and the environmental impact of a facility’s operations. Isokinetic stack sampling requires specialized equipment and expertise to ensure the sampling velocity matches that of the stack’s gas flow, which can vary based on factors like temperature, pressure, and stack geometry. The results are used to generate reports that meet environmental standards and regulations, helping companies avoid penalties and implement necessary improvements to reduce emissions.
