Air Monitoring 45 Advanced Features of CEMS Technology Improve Air Quality
Environmental protection is a leading issue in public opinion today and has resulted in increasingly strict regulations coupled with a growing demand for air emission measurements. A continuous emission monitoring system (CEMS) is the equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyser measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission limitation or standard.
The companies developing such systems do their best to provide reliable cost effective solutions and advanced features for complex energy facilities. An expert company such as Syscom 18 (Romania) offers complete solutions for stack emissions monitoring. The systems are extractive, in-situ or combined depending on customer needs and conditions within the process.
Systems as standard measure the following elements; NOx, SO2, CO, CO2 and O2 (for reference), in addition to dust in mg/Nm3 Syscom 18 is a system integrator offering complete solutions for industrial automation and process control. Syscom 18 is the direct partner of well-known global companies including; ABB Analytical GmbH, DURAG and SICK.
The systems offered by Syscom 18 have covered a wide range of applications in several areas including; metallurgy, chemical industries, power plants, cement and other construction materials.
Having more than 10 years of experience in this area, Syscom 18 is able to implement complete projects for gas analysis, from design to commissioning and turnkey delivery of the system analysis.
Reader Reply Card No. New Flue Gas Analysers Now Available
A wide range of Flue Gas Analysers are now available from Wahl Instruments (USA) Included in their Test & Calibration equipment catalogue, two different lines of analysers are available. Flue Gas Combustion Analysers are now available in two different lines; U Line models are designed for HVAC applications, for burners under 70k. G Line models are offered to serve the industrial technician, designed for burners over 70k.
Models in compliance with EPA Protocols CTM-030 and CTM-034 are available. The most commonly used fuels are pre-loaded at the factory, with other fuels available with included GasConfig software for PC on most models. By measuring the quantities and concentrations of gases present in exhaust, these combustion analysis tools allow the user to maintain the safest and most efficient
conditions possible for their environment and equipment. Detect Carbon Monoxide, Nitrous Oxide, and uncombusted hydrocarbons in the exhaust gas from your combustion process to ensure the safety of your employees and the efficiency of your equipment.
Identify maintenance problems that develop over time, as boilers deteriorate and efficiency drops. Magnetic rubber holster protects the unit from drops and allows convenient hands free operation. Built-in impact printer produces records that don’t fade the way documents printed with thermal printers can. On board memory can hold 250 readings; expand memory capacity with optional flash.
Flue Gas Analysers are available through Wahl Instruments, Inc. and its International Distribution network.

Gas Standards for Formaldehyde
Trace Source™ Permeation Tubes from Kin Tek Laboratories (USA) are used to dynamically blend trace concentrations of formaldehyde in air. Mixtures can range from low ppb to over 500 ppm.
Obtaining accurate gas standards has been particularly difficult because formaldehyde vapour condenses to a solid polymer at temperatures below 80°C, resulting in unstable concentration in stored mixtures.
In Trace Source™ permeation tubes, alpha- polyoxymethylene, a high purity formaldehyde polymer, decomposes to maintain a stable vapour pressure of formaldehyde and consequently a stable emission rate of formaldehyde. Formaldehyde emitted from the Trace Source™ tube is mixed with a known flow of zero air to form the trace concentration gas standard.
Emission flow measurements are traceable to NIST through fundamental measurements (weight change, temperature, etc.). Mixing the emission flow with a traceable flow dilution gas creates a traceable mixture.
