Environmental Compliance

There is an increasing global focus on emission reduction and control from many different sources. Tightening international and national regulations on emissions from ships are gradually being implemented. Complying with regulations is a driving force for any operation involving combustion processes. In order to achieve compliance with the environmental regulations, extensive development resources are allocated to the development of emission reduction and continuous emission monitoring solutions for gasses including NOx, SOx, CO2, PM and other polluting media.

Gas Emission Monitoring

Today, Green Instruments is one of the leading suppliers of gas emission monitoring systems for the marine industry. In 1999, when Green Instruments was formed, the G1000 Smoke Density Monitor was the very first product. By now, more than 1000 of these systems have been delivered to vessels and boiler manufacturers worldwide. In recent years, the business has also expanded in the land market.

For NOx emission monitoring, Green Instruments offers an in-situ monitoring solution which allows the direct measurement of NOx in hot, wet flue gas. Our G4100 and G4130 NOx/O2 Analyzing System is based on the newest zirconia (ZrO2) sensor technology. The system is simple and robust and can be used to monitor NOx emission from any combustion and industrial process.

Washwater Monitoring

Cleaning, or scrubbing, the exhaust gas is well accepted to be an economical method for the reduction of SOx emission. Washwater removing gaseous and particulate emissions from the exhaust gas is required to be treated prior to discharge . The requirements on washwater monitoring and discharge criteria has also been set out by the IMO in the Guidelines for EGCSs – Resolution MEPC. 259(68).

Green Instruments is a pioneer in washwater monitoring for any exhaust gas cleaning system. We can offer a total solution as well as a customized solution thanks to the modular designed of our monitoring system. The G6100 Water Monitoring System is fully compliant with IMO resolution MEPC. 259(68). The system has achieved a marine type approval by DNV/GL, RINA, Lloyd´s Register and Bureau Veritas.
