Project description: Introduction to ship exhaust desulfurization system: Human beings who are exposed to nitrogen oxides (NOx), sulfur oxides (SOx) and particulate matter (PM) for a long time will die prematurely below life expectancy. Our environment is getting hotter and hotter due to the continuous accumulation of carbon dioxide. Ship diesel engines are regarded as an important source of NOx, SOx and PM emissions, and they produce CO2. In response to these impacts, the International Maritime Organization, through its Marine Environment Protection Committee (MEPC), has developed regulations to prevent air pollution in accordance with Annex VI of the MARPOL Convention. Not only are existing Emission Control Areas (ECA) required to meet the sulfur content of tail gas emissions of 0.1%, but it will also reach 0.5% globally by 2020. EGCS technology is one of many implementations that will bring the planet back to green again. Product advantage: Scope of application/flexibility. Open: It is greatly affected by the alkalinity and salinity of seawater, and cannot operate in ports and some sea areas; closed: it is not affected by waters and can operate in global waters; hybrid: it combines the advantages of both open and closed systems, flexible switching, allowing navigation in global waters.

Main features: low-sulfur oil; no initial investment cost; simple oil transfer operation; main engine lubrication issues;LNG fuel; qualified nitrogen oxides, sulfides and particulate matter emissions;LNG fuel filling issues; must meet higher safety standards; Install scrubber towers; continue to use low-cost and high-sulfur fuel.

Technical level: Rapid payback (within 3 years); payback time depends on the price difference between high-sulfur oil and low-sulfur oil; suitable system; cost control. Open: The system is simple, no additives, low investment costs, and low operating costs; closed: the system is more complex, with higher investment costs, and high operating costs; hybrid: the system composition is more complex, and the initial equipment investment and installation costs are high.

Application prospect: It is suitable for wastewater treatment of ships, ships, submarines, aircraft carriers, etc., reducing pollution from wastewater emissions, complying with marine protection regulations, protecting marine pollution and the global environment, and equipped with three models, which can adapt to various complex scenarios according to needs., wide adaptability range and strong flexibility.
