PUMYI Company History

The total work amount of DeSox project & DeNox project reached 57000MW.

Dawootech was established

Mikrotech was established by the core R&D team of Dawootech.

1MW Scrubber test platform was completed and we got LR certificate

Strategic cooperation with Nanyang Star and Zhongtian Heavy Industry

Received three orders of newbuilding

2. Sox Legislation

IMO has confirmed clearly to ship owners, fuel companies and technology providers: The upper limit of sulfur content of 0.5%m/m fuel in the global sea will be enforced in January 1, 2020.The original four emission control zones (North America, the Caribbean Sea, the Baltic Sea and the North Sea emission control zones still implement the fuel sulfur content standard of 0.1% m/m).

Change to Low Sulphur Fuel

Convenient

Relatively small investment cost

Higher operating cost

Future availability of low sulphur fuel

Increased engine wear

Advantage ： Disadvantage ：

3. Alternatives to reducing SOx

Convert to LNG

Higher operating cost

Very high cost of reconstruction

Global refueling facilities are imperfect

Solution which also reduce NOx and Particulates.



Allows use of HFOLow lifecycle cost

No need to reconstruction engine and fuel oil supply system


High cost of one-time input

ROI is subject to the price differentbetween compliant fuel and HFO

Slightly higher power demand than Closed Loop Mode

Does not need Caustic Soda

Engine Exhaust Chemistry:

S + O2 → SO2 (~95%)

SO2 + 1/2 O2 → SO3 (~5%)

Scrubber Chemistry:

SO2 + H2O → H2SO3

SO3 + H2O → H2SO4

Seawater Reactions:

CaCO3 + H2SO3 → CaSO3 + H2O + CO2

2CaSO3 + O2 → 2CaSO4
