Overview

The GAA630-M is based on a dry and extractive approach. The system is designed as a two housing solution. The continuous gas analyzers are engineered to fit in a small footprint IP65 compact cabinet, while the sampling system is mounted in a separate IP65 enclosure. The design complies to IMO MARPOL ANNEX 14 Res. MEPC 177 (58) (NTC) & IMO MARPOL ANNEX 9 Res. MEPC 184 (59). The sampling system is based on a continuous extraction cooling device, removing the moisture from the sample gas. Both cabinets are equipped with antivibration devices to reduce vibrations effects, maximize measuring performance and extend lifetime of the analytical and pneumatic components

The unique features of the GAA630-M:

  • Unique two housing system design
  • Adaptable data communication – compatible to all advisory tools
  • Worldwide service availability
  • Type approved emission monitoring system for maritime industry
  • Proven analyzers and International Maritime Organization (IMO) referenced technology
  • Certified measurement according IMO MARPOL

Data

Measuring principle The GAA630-M is based on ABB’s proven NDIR (non-dispersive infrared) measurement technology. The analyzer module Uras26 allows for reliable measuring and monitoring of the limit values for SO2 and CO2 specified by the IMO, and it can be employed for continuous monitoring of CO if required. The O2 concentration (combustion quality index) is measured with an electrochemical sensor (ECS). The system can be equipped with an additional analyzer module to allow for NOX measurements. The Limas21 UV is a rugged photometer based on NDUV (non-dispersive ultraviolet) measurement technology specifically designed for NO and NO2 measurements.

Application

Maritime industry – background The International Maritime Organization (IMO), has introduced regulations to prevent air pollution from vessels both globally and within designated sea areas, known as Emission Control Areas (ECAs). The ECAs are geographical locations and are defined as: North Baltic Seas, all North American Coasts & Caribbean coastal areas. Other areas are under evaluation by IMO. These regulations require control on SO2 , CO2 and NOX emissions. The Maritime Industry is facing challenges to either adopt new technologies such as exhaust gas cleaning systems (EGCS) or use of low sulfur residual or distillate marine fuels to comply with the ECA requirement. Engine manufacturers and ship owner are challenged to reduce NOX emissions. The new set limits in the ECAs can be achieved only with clean fuels or by making use of DeNOX abatement systems. Ship yards, ship owners and marine ECGS manufacturers are looking to equip vessels with continuous gas analyzers for Continuous Emission Monitoring (CEM) to measure all the regulated pollutants (SO2, CO2, NOX) and to optimize fuel consumption (CO, O2) on board at the same time.
