  • Integrated real-time gas analysis solution for moisture in ammonia industry

    The highest purity of ammonia is a requisite chemical gas for the production of flat panel displays and for LEDs; the purity issue is one of achieving moisture levels at the ppb level, as in the case of epitaxial reactor applications. However, the problem requiring a solution derives in part from the fact that the FTIR spectra for moisture and ammonia overlap to the degree that the moisture peaks are masked by the ammonia peaks at high concentrations. As a result the moisture peaks cannot be used for quantitative...

    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...

    Gas monitoring instruments and systems for process NOx measurement

    Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen...

  • 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.

  • Potable water treatment

    As a selective oxidizing agent, chlorine dioxide possesses several chemical advantages when compared to the traditional use of chlorine in wastewater treatment. Chlorine dioxide does not hydrolyze in water, and thus it retains its biocidal activity over a broader range of pH. It is also non reactive with ammonia and most nitrogen-containing compounds, and thus effective at lower dose levels than chlorine. It also eliminates phenols, simple cyanides and sulfides by oxidation. Likewise it is effective at odor...

  • 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...

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...
