Marine Desulfurization
The International Maritime Organization (IMO), according to the sulphur limit regulations for ships, requires member states to implement MEPC.259(68) from January 1, 2020, that is, the
emission of sulfur oxides in the flue gas of ships must be less than 0.5%. In response to the new IMO regulations, ships basically meet emission standards in the following three ways:
1. Adding and using low-sulfur oil
2. Adopt desulfurization tower system (EGC system)
3. Use of liquefied natural gas (LNG) etc. as alternative energy
For the third method, it is generally only applicable to newly built ships or operating ships with reserved refit positions. At present, the ship industry generally adopts the first and
second methods to deal with the new regulations.
