Gas analysers s for ship scrubbers measure the concentration of pollutant gases in ship exhaust gases. These analysers s help verify compliance with maritime environmental regulations. They can monitor emissions of sulfur dioxide (SO₂) and nitrogen oxides (NOx). Gas analysers s for the shipbuilding industry enable ships to keep their scrubbers in good working order and avoid penalties for non-compliance.
Optimized control of atmospheric emissions using a compact, fast, accurate, and low-maintenance laser gas a analyser .
Monitoring exhaust gas emissions is crucial for complying with the sulfur emissions regulations in MARPOL Annex VI. The use of an exhaust gas cleaning system (EGCS) is one of the measures that can help ensure compliance with these regulations. It is also essential to continuously monitorSO₂ andCO₂ concentrations using a gas- analyser r mounted on a ship’s stack, in accordance with the guidelines for such systems (IMO Resolution MEPC.259 (68)).
We have succeeded in reducing the dimensions to 1/10th the size of a traditional analysis system.
Compared to infrared gas- analysers , the maintenance cost of theanalyser laser gas is cut in half due to the small number of parts that need to be replaced and the fact that calibration is required only once a year.
Atmospheric emission controls have been tightened to reduce sulfur oxides (SOx) emitted by ships.
The ZQS laser gasanalyser , developed by Fuji Electric, meets customer needs by providing reliable exhaust gas measurements while minimizing space requirements and maintenance.
