Why SOx Reduction?

Why SOx Reduction ?

What is SOx on Wikedpia ?

Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO2. At standard atmosphere, it is a toxic gas with a pungent, irritating, and rotten smell. The triple point is 197.69 K and 1.67kPa. It is released naturally by volcanic activity.

Inhaling sulfur dioxide is associated with increased respiratory symptoms and disease, difficulty in breathing, and premature death. In 2008, the American Conference of Governmental Industrial Hygienists reduced the short-term exposure limit to 5 parts per million (ppm)

SOx Regulation

SOx Emission is regulated by sulfur content in fuel and following regulation of sulfur content made agreement in 57th MEPC meeting.

Limit Sulfur content in the word

124.50% (45,000 ppm) – up to 2012 year
123.50% (35,000 ppm) – from 2012 year
120.50% (5,000 ppm) – enforce from 2020 year

ECAs

121.50% (15,000 ppm) by 1st, March, 2010
121.00% (10,000 ppm) from 1st, March, 2010 ~
120.10% (10,000 ppm) from 2015 year
