Gas analysers for ship scrubbers measure the gas scrubber and concentration of pollutant gases in the exhaust fumes of vessel. These gas analysers are used to verify compliance with maritime environmental protection regulations. They can monitor emissions of sulphur dioxide (SO2) and carbon dioxide (CO2). Shipbuilding gas analysers allow ships to keep their scrubbers in good working order and avoid penalties for non-compliance.
Achieving vessel emission monitoring and optimized control with compact, high speed, accurate, low-maintenance ZQS laser gas analyser.
Monitoring exhaust gas scrubbers nox sox emissions ships is crucial for compliance with MARPOL Annex VI regulations on sulphur emissions. To use an exhaust gas cleaning system EGCS, it is one of the schemes that we can take to cope with their regulation. And, it is necessary to determine and continuously monitor the concentrations of SO2 and CO2 in gas scrubber using the gas analyser mounted on a ship according to the guidelines for the systems (IMO Resolution MEPC.259 (68).
We have succeeded in reducing the size 1/10 of the infrared gas analyser type.
Compared to infrared gas analysers, the maintenance cost can be reduced and limited to less than 1/2 because the number of replacement parts is small, and its calibration is required only once a year.
Sulphur emissions shipping control has become more stringent to reduce sulfur oxides (SOx) produced from ships.
The ZQS laser gas scrubbers analyser developed by Fuji Electric, will meet the customer needs by providing precise measurements and monitoring the range of exhaust gas scrubber and by saving space and maintenance.
