Efficient measurement of SO2, NO, NO2, NH3 as well as TRS components in the Kraft pulp process

In-situ gas analyzer GM32: For emissions and process gases The tried-and-tested in-situ GM32 analyzer from SICK – optimized for non-contact measurement in emissions plants as well as for process gases – is available in several versions: a standard version, an Atex version and with optimized analysis technology for TRS measurement in the Kraft pulp industry. Direct in-situ measurement With the GM32 in-situ gas analyzer, your control technology systems are able to work with actual values in "real time". This is because it measures reactive gases including pressure and temperature in-situ, in...

Open GMP measuring probe Measuring probe version GM32 is available with two measuring probe types: with open measuring path •• GPP gas diffusion probe Sender/receiver unit Cross-duct version The sender/receiver and reflector units in the GM32 are installed adjacently to each other at the measuring site. Reflector unit Sender/receiver unit Atex version GM32 Ex with GMP measuring probe Open GMP measuring probe Sender/receiver unit in Atex design Measuring probe version Cross-duct version Designed for ATEX zones This version proves its strengths: The cross-duct version is suitable for the...

In-situ measurement in ATEX zones: a new solution for familiar tasks GM32 gas analyzers with in-situ measuring technology have a long track record both in emissions monitoring as well as in process control applications. Now the rugged GM32 is also available in an ATEX version as the GM32 Ex, with cross-duct and measuring probe versions for gas temperatures up to 650°C, for example, for use in the chemicals industry or refineries, but also for measuring tasks in the natural gas or crude oil industry as well as emissions monitoring supporting sulfur recovery plants or FCC plants. A wide scope...

Simple, precise, cost-effective: TRS emissions safely under control The first and only direct TRS measurement in the Kraft pulp process: GM32 TRS-PE (PE = Pulp Emission) from SICK. TRS measurement success in the Kraft pulp industry UV spectroscopy – the optimal measuring technology Lime kilns and black liquor recovery boiler for the source for TRS components in Kraft pulp plants. The limit values for these emissions are strictly regulated by the authorities and are typically set between 5 ... 30 mg/m3 (3 ... 20 ppm). Depending on restriction, hydrogen sulfide (H2S) must be monitored alone...

Monitoring and control of flue gas in purification plants The in-situ GM32 analyzer with its optimized measuring technology is suitable for nitrogen oxide measurement for controlling catalytic processes in flue gas denitrification and desulfurization plants. The GM32 is the best choice, especially in situations where rapid measurement is required directly in the gas duct, even under high dust loads or where saturated sample gas is expected. Flue gas denitrification plants – fast, unaltered measurement Environment protection laws demand reduction of nitrogen oxide (NOx content) in flue...

Desulphurization plants and emissions measurement Desulphurization plants (DeSOx) use, among other things, wet scrubber systems in order to spray the flue gas with a calcareous solution after the dust has been removed. This process causes the sulfur oxides in the flue gas to react and be converted to calcium sulfite or sulfate. These products are then removed from the process by dehydration. Alternatively, compressed air can be added to the sulfite sludge causing the calcium sulfite to oxidize into gypsum. The GM32 from SICK has also proven itself in such process control applications as...

Measure aggressive gases directly and quickly – even in ATEX zones Product description The GM32 in-situ gas analyzer measures SO2, NO, NO2 and NH3, as well as TRS components in Kraft pulp processes including pressure and temperature in the gas duct. Direct, fast and without gas sampling and transport. This means control systems are able to work with actual values in real time. Due to self-monitoring, the measured values are reliable. In case of deviations an early warning will be shown. For emission measurement of SO2 and NO, GM32 is tested for suitability according to European standard EN...
