Description
Technical Field
The invention relates to the technical field of ship manufacturing, in particular to an environment-friendly ship.
Background
Ships use sulfur-containing heavy oil as fuel, and sulfur oxides (SOx) are produced during combustion. The sulfur oxides in the air can form acid rain, causing environmental pollution. The control of the emission of the sulfur oxides in ships is increasingly paid attention by the international society, and the international maritime organization and the governments of various countries establish relevant regulations for reducing the emission of the sulfur oxides. The international maritime organization defines the borea and the north sea as sulfur oxide emission control areas where only fuels with a sulfur content of not more than 1.5% can be used. Harbors in the united states, europe, etc. also impose specific limits on the sulfur content of docked ship fuels, such as the borea, north sea, north america, and the caribbean of the united states, with an upper limit of 0.1% sulfur in the specified region. At the MEPC71 conference, IMO confirmed that global waters began to enforce the 0.5% sulfur emission limits on 1 month 1 year 2020.
