Ammonia Monitoring Applications

  • NH3 Monitoring in Air

    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

    Improved monitoring and automation can deliver more efficient waste treatment and reduced energy consumption and improved effluent quality. The cost of treatment and the quality of effluent discharge can thus be significantly reduced.

  • Final effluent monitoring for wastewater treatment industry

    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.

    Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    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.

    Water quality monitoring for dairy industry

    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

    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.

    Gas monitoring instruments and systems for DeNOx process control

    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 NH3 emissions from livestock enclosures

    Ammonia (NH3) is formed from the breakdown of urea in slurry and manure, and hence this is the main source of NH3 emission in the UK. High levels of NH3 emissions can cause a large amount of environmental damage to vegetation. As well as the outward environmental impact, high NH3 concentrations in and around livestock enclosures have a detrimental effect on the health and well-being of the animals.

    Measurement solution for high NH3 monitoring from wastewater

    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.
