Open-Loop Exhaust-Gas Cleaning System: Analysis of Effects Produced on Barcelona Port Water pH

The implementation of a 0.5% mass/mass sulphur cap in fuels used by ships has become reality. Furthermore, regulation 14 the MARPOL Convention–Annex VI (amended) establishes that limit on fuel operating Sulphur Emission Control Area (SECA) cannot exceed 0.1% mass/mass. To deal with these requirements while considering nature shipping business, which is continuous carriage cargo around world, shipowners or companies have few options for following this regulation. Apart from use low-sulphur-content an exhaust-gas cleaning system, also known as “scrubbers”, alternative. systems, specifically open-loop entails discharge to sea residual water during process exhaust gases ship engines. objective paper study effect produced discharging acidity level (pH) Barcelona port water. This was achieved through periodical sampling and analysis collaboration IDAEA (CSIC) laboratory. We analysed evolution pH results obtained so far initial picture situation real time regarding wash-water discharges scrubbers. describes system going improve operation systems.
