NH3 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.

Sludge monitoring for water and wastewater industry

Water quality monitoring for dairy industry

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Continuous monitoring of process streams and waste streams in a dairy industry setting can provide various benefits to the operators. One major benefit is that it is possible to minimize product lost to the waste stream by means of reliable online monitoring of organics (TOC) at various points in the plant. In addition, due to the nitrogen deficient nature of milk wastes it is possible to optimize ammonia dosing by accurately and continuously monitoring the organic loads entering the waste stream.

Air pollution control solution for the Ammonia and odour

by Macrotek Inc.     based in Markham, ONTARIO (CANADA)

Control of emissions is often required due to the hazardous nature of the contaminant. Often, control or removal is necessary due to offensive odours. Ammonia, sulfur and other related compounds fall in these categories. Macrotek offers many control technologies to capture ammonia and other odour causing contaminants. Reagents are often used to neutralize and stabilize the by-product.

Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

Final effluent monitoring for wastewater treatment industry

by Pollution & Process Monitoring Ltd     based in Sevenoaks, UNITED KINGDOM

Industry and municipal waste-water (sewage) treatment plants have had to respond to environmental legislation such as the Urban Waste Water Directive, IPC, IPPC and now the EPR (Environmental Permitting Regulations). As successive legislation becomes more stringent, discharge consents have been progressively tightened, and the need for self-regulation has become more important. As a consequence, on-line instrumentation has been installed throughout waste-water industry to continuously to provide final effluent monitoring and perform water analysis for key consent parameters.

Gas Detection Solutions for Fertilizer Manufacturing

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example, water vapor) – such interferences complicate other optical techniques using IR or UV.

Gas monitoring instruments and systems for DeNOx process control

by Gasmet Technologies Oy     based in Helsinki, FINLAND

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.

Measurement solution for high NH3 monitoring from wastewater

by Protea Limited     based in Middlewich, UNITED KINGDOM

Protea was asked to supply a high level ammonia (NH3) measurement system for a waste water treatment plant. The reflux drums at the inlet to two ammonia stripping towers needed to be measured continuously. Protea designed a solution based around our Solus TDLAS analyser platform and a high level dilution system. The Solus analyser was configured for NH3 measurements in the range 0-500ppm. A dilution system incorporating special dilution probe and 19` control panel was installed before the analyser. This gave a dilution level of 600:1, enabling the NH3 analyser to measure in the range 0-30% Volume.

Ammonia (NH3) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Ammonia is a compound featuring a nitrogen molecule attached to three hydrogen molecules (NH3). It is a colorless gas with a characteristic pungent smell similar to human urine, as urine contains a large amount of ammonia in it.

by Absolute Systems Inc.     based in Edmonton, ALBERTA (CANADA)

Ozone provides both economical and ecological advantages to the Aquaculture industry. Ozone oxidation of aqua-farms improve water quality, destroys organics,  and increases DO levels which result  in faster growth rates, decreased death tolls, and provides an overall healthier and safe environment for fish.

Continuous emissions monitoring for mineral wool production

by Opsis AB     based in Furulund, SWEDEN

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.

Continuous emissions monitoring for CO2 capture

by Opsis AB     based in Furulund, SWEDEN

The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. 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.
