Dilution Extractive CEMS
Cemtek offers custom-built Dilution Extractive CEMS manufactured to your application’s unique specifications. Our technicians will work one on one with you to design, engineer, construct, deliver and install your tailor made product. Dilution extractive systems are very well suited for harsh applications where high levels of gases, acids, moisture & pollutants are encountered.
An air driven eductor pump extracts a sample of flue gas and transfers it into the CEM system via a dilution extractive sample probe. An air clean-up assembly cleans, scrubs & dries compressed air to a -70F dew point to create “dilution air”. The dilution air is mixed with flue gas which is drawn through a critical orifice and mixed with dilution air, typically at a 100:1 ratio. The diluted sample is than transported through a sample line to a manifold. At that point individual analyzers may extract a sample to test.
Techniques employed for this vary from gas to gas for example chemiluminescence is used to test for NOx, Pulsed Fluorescence, UV & NDUV for SO2 and NDIR or Gas Filter Correlation technique for CO and CO2. The signal output from each analyzer is received by a Data Acquisition and Handling System (DAHS) which collects and records the emissions data.
Cemtek’s highly experienced engineering department will engineer the system to meet the monitoring requirements while keeping future maintenance costs to a minimum. Our dilution extractive CEM system comes with a variety of options. We carefully select the measurement technology for your specific application. The system is designed with the user in mind with open panels and analyzers with state of the art components arranged for easy access.
