Ship "s" limited to sulfur "broken pollution problem

In the field of air pollution control, China has been in the regulation of vehicle emissions and industrial emissions of a comprehensive strict control. However, the challenge of environmental air quality still exists in the coastal and river regions, especially in the port city, and the control of the emission of sulfur oxides, nitrogen oxides and particulate matter is very important. In this regard, China's introduction of the new deal, set up "ship emission control area", since April 1 this year, the Yangtze River Delta region will take the lead in the implementation of emission reduction requirements, ship in the waters of the Yangtze River Delta emissions control core area of port shore parked during using sulfur content not more than 0.5% of the fuel.
For global shipping and logistics giant China round - Wilson logistics company, they can do more for environmental protection. Recently, China round - Wilson announced in Beijing, its ships in the global port has started to use sulfur content of less than 0.1% of the fuel, to reduce sulfur dioxide emissions and environmental pollution.
According to Hua round - vice president of Wilson and sustainable development responsible for Anna Larsson introduction, in the application of low sulfur fuel in China wheel Wilson to maintain long-term industry leading position, in 2005, the company began to implement the global limit sulfur policy, fleet fuel used the average sulfur content is limited to below 1.5%, significantly lower than the shipping industry 3.5%, 2.7% of the average level of sulfur content.
"Thus reducing the sulfur emissions by about 220 thousand tons to the atmosphere, which is almost the total amount of sulfur dioxide emissions in France in 2012." Larsson Anna told the China economic times reporter.
Excessive sulfur emissions
Sulfur emissions have been shown to be harmful to health and the environment, the United States Environmental Protection Agency collected considerable evidence shows that, short-term 5 minutes to 24 hours of exposure to sulfur dioxide will bring a series of negative effects on the respiratory system, including bronchoconstriction and exacerbates asthmatic symptoms. Sulfur oxides may also react with other compounds in the atmosphere, forming small particles that penetrate the sensitive part of the lungs, leading to or exacerbate respiratory diseases, such as emphysema and bronchitis. It can also aggravate the condition of the heart disease patients, increase the number of hospital admissions, causing premature death.
And fuel oil ship in about 90% of sulfur components in the engine by burning will react with oxygen, and the tail gas in the form of sulfur dioxide emissions out and therefore rely on rich in sulfur fuel oil shipping industry has always occupied a large proportion in the overall emissions of sulphur.
Although sulfur emissions have been shown to pose a threat to health and the environment, most ports in the world are still not included in the control area of sulfur oxide emissions. Port city of sulfur emissions reduction is still a lack of unified supervision, at present by countries, port authorities, ship owners and operators self management.
International shipping industry 70% of sulfur emissions in the distance from the coastline of 400 kilometers within the main trade routes. A number of studies have shown that in the sea breeze under the action of shipping emissions can invade hundreds of kilometers inland.
Several countries have already taken steps to reduce the emissions of sulfur oxides through domestic regulation. In 2006, the International Maritime Organization (IMO) International prevent caused by ship pollution convention MARPOL Annex VI "to prevent the ship caused by air pollution" on the ship, the sulfur oxide emissions set up limit the overall. The annex also led to the establishment of sulfur emission control area SECA. The upper limit of sulfur content in the area is 0.1%. The sulfur emission control area is implemented in Europe and North America since January 2015.
