Gas analysers for ship scrubbers measure the concentration of pollutant gases in ship exhaust fumes. These analysers can be used to check compliance with maritime environmental protection regulations. They can monitor emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx). Shipbuilding gas analysers enable ships to keep their scrubbers in good working order and avoid penalties for non-compliance.
Optimized control of atmospheric emissions thanks to a compact, fast, precise and low-maintenance laser gas analyser .
Monitoring exhaust emissions is crucial to comply with MARPOL Annex VI regulations on sulfur emissions. The use of an exhaust gas cleaning system (EGCS) is one way of complying with these regulations. It is also essential to continuously monitor SO2 andCO2 concentrations using a gas analyser mounted on a ship's stack, in accordance with the system guidelines (IMO resolution MEPC.259 (68).
We have succeeded in reducing the dimensions to 1/10th the size of a traditional analysis system.
Compared with infrared gas analysers , the cost of maintaining a laser gasanalyser is cut in half, thanks to the low number of parts to be replaced and the fact that calibration is only necessary 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 measurement while limiting space and maintenance requirements.
