Nitrogen Oxides (NOx) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.

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.

Flaring Solutions for the Landfill Industry - Leachate Evaporation

by ABUTEC LLC     based in Kennesaw, GEORGIA (US) (USA)

Increased concern for the environment has led to new opportunities for landfills to better manage their waste gas. ABUTEC works with the landfill industry to ensure that leachate evaporation is handled in the most efficient way possible. ABUTEC’s high temperature enclosed combustors meet state and federal regulations for burning landfill waste gas at a minimum of 99% destruction and removal efficiency (DRE), meaning almost 100 percent of the vapor to be destroyed is converted to CO and water. These combustors are of high quality, flexibility, low emissions, CSA-approved and able to burn very low calorific gas. When combined with a heat exchanger, the unit can efficiently evaporate the leachate eliminating the need for expensive trucking or disposal.

Incineration Industry Emissions Monitoring & Analysis

by Procal - Parker Hannifin Corp     based in Peterborough, UNITED KINGDOM

Monitoring of emissions from incinerators is a demanding application for Continuous Emission Monitoring Systems. The emissions produced are highly corrosive, some of the gases are soluble and, because the waste being burnt is constantly changing, the resulting stack gas temperature varies widely.

PLAZKAT systems for treatment of emissions in the petrochemical industry

by Plasma Air Systems Corporation     based in Harju Maakond, ESTONIA

Today, the reduction of atmospheric emissions produced by the gas processing and petrochemical industries is an acute problem. The most widely used technique of exhaust gas treatment comprises complete burning, even though this method does not provide an adequate degree of treatment. Therefore, in this case PLAZKAT systems are a more effective solution for removing aromatic hydrocarbon from the emissions.

Ethanol and Biofuels

by Babcock & Wilcox MEGTEC     based in De Pere, WISCONSIN (USA)

Controlling the VOCs and CO emissions produced in the feed dryers (wet and dry milling), coupled with the particulate matter being introduced and the need for the reduction of NOx are just the start of having a successful abatement solution. The challenges of smooth pressure control that reduces dryer fluctuations and plug resistant media that lessen the frequency of bake-outs are also part of a successful abatement system and we have the solutions. Our engineered oxidation systems provide reliable performance with minimal maintenance requirements. Externally accessible valve bearings and other critical components are kept out of the corrosive moisture-laden streams extending the life of the equipment and facilitate maintenance intervals. Our simple oxidizer designs control your emissions with minimal facility intervention and allow us to provide you with reliable and dependable equipment.

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.

Continuous emissions monitoring in cement kilns

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.

Measurement solution for CO2 capture by amine absorption

by Protea Limited     based in Middlewich, UNITED KINGDOM

The act of capturing and storing CO2 produced from large scale combustion plants such as power stations is becoming more and more favourable and feasible. One of the most common post-combustion CO2 capture methods is by absorption. The absorption plant can be added on to the existing combustion process, with the flue gas first passing through an absorption column where the CO2 reacts with an absorber. Amines of different types are used as the absorber. An amine CO2 capture plant can capture as much as 90% of the CO2 emitted from the power station and so has a real benefit for the environment. Having said this, care needs to be taken to ensure that amine emissions themselves are monitored, managed and prove no extra damage to the environment. Research is on-going to develop new amines or mixtures of amines to reduce emissions. The most common absorber in use in today’s first generation of industrial pilot plants is Monoethanolamine (MEA).

Emissions testing for engines

by Testo Inc.     based in Sparta, NEW JERSEY (USA)

Rich-burn engine exhaust, when uncontrolled, can have wide concentration ranges and both CO and NOX can fluctuate significantly. The on-board CO dilution system will automatically set-up for optimum testing, perfect for a rich burn engine. Lean-burn engines have different exhaust characteristics, but NO2 can make up a significant portion of the total NOX measurement. The 350 measures both NO and NO2 for proper lean-burn engine set-up. Due to high concentration, replaceable interference filters keep the sensors stable and your readings accurate. High exhaust pressures and heavy particulate loading are easily controlled with the special pressure relief valve (standard) on the engine probe configuration.

DeNox Systems

by NEWLAND ENTECH EUROPE     based in VILLAVICIOSA DE ODON, SPAIN

Newland Entech Europe could reducing NOx emissions adding ozone to the flue gas before it enters the chimney. The ozone convert the NOx to N2O5, which it is high soluble in water and is easily removed from the flue gas by a scrubber.

Secundary air flow measurement for power generation industry

by Kurz Instruments, Inc.     based in Monterey, CALIFORNIA (USA)

Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes.
