The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.
The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is...
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...
Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of...
Make more out of your mill. OPSIS tested and approved monitoring systems provide cost-effective and reliable on-line monitoring of several gas compounds, such as both high and low concentrations of methane, moisture, carbon dioxide and hydrogen sulphide, at several locations.
Anguil is intimately familiar with the emission capture, control and compliance hurdles that both composite and carbon fiber producers face. So much so that we have developed specific technologies that address the unique needs of our customers in both industries. Please visit our Carbon Fiber Page to explore Anguil`s proprietary oxidizer designs for furnace and oven emissions. On composite applications, firms continue to battle emission levels by lowering styrene content in the resins they utilize. However,...
The carbon fiber manufacturing industry requires a unique process control solution that conventional gas detection technology lacks. Boreal Laser’s line-of-sight laser based gas detection system is the perfect fit for measuring HF in various pan oven applications and stack emissions monitoring . Whether you are looking for gas detection solutions for safety, environmental or process control needs Boreal Laser has you covered.
With its expertise in calculating and managing emissions data, CERC offers a range of services to assess greenhouse gas emissions, from determining the carbon footprint of a single industrial process, to compiling a greenhouse gas inventory for a whole geographical area.
CERC uses methods and emission factors laid out by the Intergovernmental Panel on Climate Change (IPCC). Emissions from transport, industrial, heating and agricultural activities are calculated and stored using the EMIT software package.
Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.
For the removal of mercury emissions from flue gas streams, Calgon Carbon`s specialty PAC products are proven industry performers. These industries include: Coal-fired electric power plants, Cement, Boilers.
PLAZKAT Aero systems are used to treat emissions from motor and railroad vehicles. It has been found that exhaust gases from internal combustion engines (ICE) contain over 250 ingredients. Major components include carbon oxides, nitrogen oxides and hydrocarbons.
Metal casting and heat treatment processes are associated with harmful gaseous emissions into the atmosphere which include substances such as carbon monoxide, nitrous oxides, oil vapors and sulfur dioxide.
As is the case for many industrial manufacturing processes, emissions are best destroyed through the use of thermal and catalytic oxidation technologies. Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) are destroyed through the use of high temperature combustion with direct heat recovery. The harmful air pollutants are converted to heat, water vapor and carbon dioxide, creating a destruction efficiency greater than 99%.
In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.
By converting dead trees into wood chips and gasifying them, our machine produces clean electricity and offsets disposal costs.
Disposal by gasification also has far lower particulate emissions than controlled burns and a lower carbon footprint than decomposition, since methane emissions from anaerobic decomposition are avoided. Decomposing wood reverts all of its carbon content to CO2, but gasification sequesters a portion of it as charcoal waste, usable as biochar.
Citto Activated Carbon 'Air Series' offers a range of standard, impregnated, and specialized activated carbon products for a wide spectrum of air purification applications. The dynamic product array of the Citto Activated Carbon 'Air Series' is developed to meet stringent emission control regulations as well as safety standards for emerging respiratory technologies effectively removing nuisance odors, volatile organics, and hazardous chemicals from air and gas streams.
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.
Total Volatile Organic Compounds (VOCs) is a common measurement required from industrial emissions. Commonly, a single measurement value is obtained through the use of a Flame Ionisation Detection (FID) analyser. The pyrolysis of the gas stream in a FID analyser allows it to make a measurement of the carbon content of the gas stream. FID analyser cannot indicate the relative abundances of different organic species in a gas stream and often have widely different responses for different gases. However, they are...
The recent COP 21 meeting reexposed the need for global coordination to monitor Green House Gases (GHG) as well as emissions of ChloroFluoroCarbons (CFC). Networks of sensors have been deployed over the Earth to measure concentration of gases such as methane, carbon monoxide, ethane, carbon dioxide, nitrous oxide, nitrogen oxide and dioxide (NOx)… Such task requires instrument with not only ultra high accuracy but also ultra high precision. Our QCNose Instruments have been designed for such operations...
