GAA330-M EMISSION MONITORING SYSTEM FOR MARINE APPLICATIONS | DS/GAA330-M-EN REV. B 3

— System description

Application On January 1, 2015, new limit values for SO2 and NOx went into ef-fect to reduce air pollution caused by ships. The International Maritime Organization (IMO) has specified these new limit values in MARPOL Annex VI. If a vessel uses an exhaust gas cleaning sys-tem – a so-called scrubber – for compliance with the limit values, this system must be continuously monitored by means of an emission measurement system.

The GAA330-M measures the SO2 and CO2 concentration upstream or downstream of the scrubber and transfers them to the vessel’s main control system. Compliance with the specified limit values can be proven and documented this way. The measured ratio of SO2 and CO2 can be used to control the scrubber. Optionally, the measuring system can also measure and report the NOx values.

Measuring principle The GAA330-M measuring system 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.

The system can be equipped with an additional analyzer module to allow for NOx measurements. The Limas21 UV is a rugged photo-meter based on NDUV (non-dispersive ultraviolet) measurement technology specifically designed for NO and NO2 measurements.

System configuration The system allows for simultaneous monitoring of multiple measuring points and different measured components. It can be configured for either a single stream or a dual stream sampling (see table below and gas flow diagrams on pages 5 to 9).

System design The system’s space-saving and robust design makes it easy to in-stall or retrofit on site. Due to the innovative technology, a practi-cal calibration system and a self-cleaning probe, the system re-quires very little maintenance. The analyzer consists of a thermo-stat-controlled sensor and a control unit in a 19-inch rack housing.

Main system components • Gas sampling probe with heated filter unit • Heated sample gas line • Sample gas cooler • Gas feed pump • Gas analyzer • Analyzer cabinet

Options • Air conditioning unit, 500 W • Gas sampling probe with 2 × 2/2-way valves for automatic

back-purging • Additional measurements: NOx • Addition of a second parallel sample line

Approvals, compliance Marine directives and rules

The analyzer system complies with: • MARPOL Annex VI and NTC 2008 – MEPC.177(58) • Guidelines for exhaust gas cleaning systems – MEPC.184(59),

MEPC.259(68) • Guidelines for on-board nox verification procedure – Direct

measurement and monitoring method

Safety, electromagnetic compatibility

The analyzer system complies with the provisions of the European Directives • 2014/30/EU (electromagnetic compatibility) and • 2014/35/EU (low voltage).
