ANDRITZ SeaSOx technology
The International Maritime Organization (IMO) has introduced regulations for emission control under Annex VI of the MARPOL Convention. It defines mandatory limits on emissions of sulfur oxides (SOx) and nitrogen oxides (NOx), both globally and within designated sea areas known as Emission Control Areas (ECAs).
ANDRITZ has developed the SeaSOx technology, which is the right solution to clean exhaust gas in order to meet the new requirements. It can be installed on all types of ships, either on a new build or retrofit basis, thanks to its flexibility.
The ANDRITZ SeaSOx technology has clear advantages:
- Simple and robust design
- Substantial reduction of absorber noise: A smaller silencer can be used if operated in inline mode.
- Exhaust gas can pass through safely, even when the SeaSOx plant is not operating.
- Highest removal efficiencies with lowest operating costs, combining ANDRITZ proprietary FGDplus (Flue gas desulphurization) technology and optimized spray bank design
The key equipment in this technology is the advanced ANDRITZ SeaSOx scrubber, which is designed on the basis of more than 30 years of experience in scrubber design and using the most highly developed CFD models to simulate and optimize flow distribution and SOx mass transfer.
The SeaSOx technology can operate in the open loop mode, where the alkalinity of seawater is used as the washing medium, as well as in the closed loop mode, where the natural alkalinity is too low or discharging of effluent is prohibited and a neutralizing agent (NaOH, Na2CO3, MgO) has to be added.
ANDRITZ is a leading international provider of innovative air pollution control technologies, offering dedusting systems, DeNOx systems (SCR), dry as well as wet flue gas cleaning (multistage), and ANDRITZ SeaSOx exhaust gas cleaning for the maritime industry.
