Flue gas denitration on-line continuous monitoring solution
Nitrogen oxide (NOx) is one of the main sources of air pollution, not only it has significant influence on global warming, but also involved in the destruction of the ozone layer. Technical measures to control NOx emissions can be divided into two categories: one is so-called source control, the characteristic is by a variety of technical means, to control NOx generation in the process of combustion reaction (i.e., low NOx combustion technology). Another kind is the so-called tail control, the characteristic is ...

Energy reduction and coagulation process control for wastewater treatment industry
One of the biggest costs for water-water treatment is energy consumption; the cost of which is likely to escalate with increased demand. Ineffective process control may not only be costly but environmentally impacts though the inefficient use of an un-renewable resource. Furthermore, poor process control in one area may also impinge on neighbouring processes ultimately affecting effluent water ...

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 ...

Water Quality Monitoring Solutions for Aquaculture
Water quality is a critical factor in modern intensive fish farming management. Impaired water quality can not only directly cause mortality, but more often, it also stresses aquatic species and makes them more susceptible to infectious diseases. Optimal water quality varies by species and must be monitored to ensure survival and healthy growth. In addition, the quality of water in fish farming systems can significantly affect the costs associated with getting products to the market. Water quality parameters that ...

Industrial monitoring solutions for the de-NOx plants areas
In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to allow ...

Trace gas analyzers for ammonia in hydrocarbons applications
Introduction: Ammonia (NH3) is a well-known, widely spread air pollutant, which is present almost everywhere in low ppm/ppb concentrations. So this chemical can be found in various processes, where gases are the basic media, such as steam crackers producing gaseous hydrocarbons for further production steps like polymerization. Gases like this are for example Ethylene, Propylene and even so called cracker gas, which is mostly a mixture of above mentioned gases as well as Water and Hydrogen. The gases of interest ...

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 ...

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 ...
