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.
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.
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,...
A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.
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.
The radiello ammonia sampler impregnated with phosphoric acid represents a low-cost, reliable and simple tool for assessing the atmospheric deposition of ammonia at parts per billion (ppb) concentration levels.
To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from...
The most important parameters in Water/Steam Cycles such as Cation conductivity, dissolved oxygen and pH are available as pre-assembled and factory tested units. Dedicated analyzers for sodium, silica, phosphate and hydrazine are also factory tested and calibrated for immediate operation.
The installation of suitable installation material in buildings is a cost effective way to reduce energy costs. The manufacture of insulation from minerals or mineral products, such as glass. Recycling glass to form insulation materials is another way to keep the process "green".
The release of refrigerant gases into the environment can be harmful to both the potential occupants of the space, as well as to the environment in general. Chlorofluorocarbons, commonly known as CFCs, which were formerly considered relatively safe, are now known to be a key contributor to the thinning of the ozone layer. These are gradually being replaced by more environmentally friendly refrigerants such as R134a. This however, does not lessen the need for leak detection. Regardless of their reduced impact on...
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.
