2 GAA330- Emission monitoring system for marine applications Application and system design Application On January 1, 2015, new limit values for SO2 and NOx went into effect to reduce air pollution caused by ships. The International aritime Organization (IO) has specified these new limit values in ARPOL Annex VI. If a vessel uses an exhaust gas cleaning system 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- 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. easuring principle The GAA330- 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 IO. 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. System configuration The system allows for simultaneous monitoring of multiple measuring points and different measured values. It can be configured for either a single stream or a dual stream sampling (see table below and gas flow diagrams on pages 4 to 8). System configuration Sampling points Streams easured components C1 Downstream scrubber Single CO2, SO2 C2 Upstream scrubber and Dual CO2 and Downstream scrubber SO2 C3 Downstream scrubber Dual CO2, SO2 C4 Downstream scrubber Single CO2, SO2, NOx C5 Upstream or w/o scrubber Single CO2, NOx System design The system s space-saving and robust design makes it easy to install or retrofit on site. Due to the innovative technology, a practical calibration system and a self-cleaning probe, the system requires very little maintenance. The analyzer consists of a thermostat-controlled sensor and a control unit in a 19-inch rack housing. ain system components Gas sampling probe with heated filter unit Heated sample gas line cooler Gas feed 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 2 DS/GAA330--EN Rev.
