A wide variety of products that are used in our indoor environments may emit harmful substances, raising health and safety concerns in homes, offices, public places and vehicles. There is increasing demand to reduce VOC emissions from indoor sources, backed by European legislation. REACH regulation is a European initiative for the Registration, Evaluation, Authorisation and Restriction of Chemical Substances. It was implemented to protect human health and the environment from harmful emissions of chemicals into...
Process control and emissions monitoring in a mineral wool plant is a challenge due to the presence of phenol and formaldehyde. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS DOAS system is different and provides plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.
The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.
A key issue in the measurement of the products of combustion in Cement and Lime industries is the high levels of particulates. The Procal 2000 in situ analyser`s heated probe option is especially suited to this industry as it efficiently deals with variations in process temperature, keeping the probe above the sample dew point and safe from corrosive condensate.
The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.
Motor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world. Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels. These toxic fumes cause smog in the atmosphere, which can affect very broad regional air sheds and contribute to the formation of cancer. Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air...
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.
The inherent flexibility of Procal analysers enables the instruments to be configured to meet Customer’s specific requirements. Their capability to monitor gas concentrations at elevated pressures and temperatures make Procal products ideal for process applications in the Chemical Industry.
From monitoring impurities in vents, stacks, air or water to point source or area monitoring, automatic and on-line measurement is an important tool. This type of measurement will detect, quantify and assist in reducing emissions. Siemens analytical products are utilized for many of these measurements.
Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.
In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.
Triboelectric dust probes installed in the clean gas duct after bag filters, cartridge filters or centrifugal separators (cyclones) are used to detect faulty, damaged or leaking filters. This early detection of failures minimises product loss, improves environmental conditions and problematic dust emissions.
Benefits include low initial outlay, no consumables and low maintenance requirements.
There are more than 10,000 Dr. Foedisch filter monitor devices installed worldwide in the food processing, cement,...
Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...

Noise emission values are increasingly becoming marketable items for machines, equipment and appliances - low noise emissions directly relate to lower noise exposure for product users and bystanders. Retail customers, both private and corporate, appreciate this relationship and are, therefore, more aware of noise emission declarations on goods when deciding their purchases.
The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a...
