Gas monitoring instruments and systems for nitric acid process

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective Catalytic Reduction unit (SCR), which deploys ammonia gas NH3 to limit emissions of NO and NO2. A modern nitric acid plant needs to monitor the emissions of these gases.

Industrial air pollution control for the chemical and petrochemical industry

by Chemisch Thermische Prozesstechnik GmbH / CTP Air Pollution Control     based in Graz, AUSTRIA

CTP systems can be found in every leading production company: thanks to the experience and the expertise developed in partnership with our customers for processes with inconsistent waste gas volumes; varying concentrations of organic components; gases contaminated with aerosols. CTP has installed systems for waste gas streams ranging from 1,000 to 200,000 Nm³/h. CTP supplies this industry with mainly catalytic systems, regenerative thermal oxidisers (RTO) and adsorbers. As the flue gases in this industry are often explosive mixtures, CTP systems have to be completed with special safety conduits and filters to help reduce hazards during continued operation.

Catalysis

by Hiden Analytical     based in Warrington, UNITED KINGDOM

Hiden's modular CATLAB offers a wide range of experimental tools for catalyst researchers, from rapid dynamic screening to fully automated precise investigations of active surface chemistry & optimisation of catalytic activity. The CATLAB performs analysis using temperature programmed methods such as TPR/TPO/TPD. Pulse chemisorption is also available with the CATLAB-PCS. The integrated QGA mass spectrometer system provides for quantification of the adsorbed/desorbed species. Physical analyses such as metal surface area, catalyst dispersion and surface acidity/basicity are provided. All CATLAB & mass spectrometer sampling wetted surfaces are designed to have the widest possible compatibility for use with aggressive species. Hiden Analytical’s HPR-20 QIC mass spectrometer is available for coupling to existing catalyst reactors with integral analysis software available for TPD/TPR/TPO quantification. A range of specialized connectors & couplings optimise integration with reactor vessel
