Hydrocarbons are a family of organic chemicals consisting of carbon and hydrogen atoms arranged in a variety of ways. Hydrocarbons are found naturally in crude oil and are released into the environment with its combustion (power plants, home heaters etc).
For large combustion plants and power plants we offer the DCEM 2100 particulate monitor. This monitor is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It offers outputs in Transmission, Opacity and mg/m3 (when calibrated against a Standard Reference Method). The DCEM 2100 offers real-time zero and span calibration and an efficient air purge system to prevent optical contamination.
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. The analyser can be configured for single channel operation to monitor any of these gases plus CH4 and HCl.
CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4...
In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow...
CO (carbon monoxide) and CO2 (carbon dioxide) are generally measured to ensure process control. CO2 is the desired product and CO is undesired in combustion since it will explode in high enough concentrations. CO2 and CO concentrations can also be used to determine other process-specific efficiencies. Continuous emissions monitoring equipment that can be calibrated as a CO and CO2 analyzer is thereby essential for process control.

GasFinder2 can be permanently installed to monitor chemical and petroleum plants for both combustible and toxic gases. GasFinder2 can be used to replace arrays of point sensors for perimeter monitoring. A single light path will replace many point sensors. With GasFinder2 perimeter monitoring, all gas dispersed from a facility is detected and logged.
Sulfur Dioxide (SO2) is the product of the combustion of sulfur compounds and causes significant environmental pollution. The main source of sulfur dioxide SO2 in the environment are from various industrial processes such as the burning of coal in power stations, the extraction of metals from ore and combustion of fuel within automobiles.
Carbon monoxide poisoning is the most common type of fatal poisoning in many industrialized countries. Carbon monoxide is a colourless, odorless and tasteless gas caused by the incomplete combustion of hydrocarbon fuels. Carbon monoxide is a toxic gas to the human body, when inhaled it binds to hemoglobin, myoglobin, and mitochondrial cytochrome oxidase reducing oxygen storage, transport and respiration in these organelles.
Carbon dioxide (CO2) is emitted in a number of ways. It is emitted naturally and through human activities like the burning of fossil fuels. Carbon dioxide (CO2) is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Small amounts of carbon dioxide are emitted from volcanoes and other geothermal processes.
Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.
