Abstract
This paper presents an innovative worldwide method of total of gas combustion-derived ships on heavy fuel diesel engines. For the treatment of waste aqueous solution derived from with aqueous solution NaOH the exhaust gas and capture the S from . For the treatment wastewater plant is necessary to have big surface and quantity of salt water. But unfortunately, the space free on the ships are very restricted and further consequently born stability problems for the ships. This proposal innovative methodology with new approx and new design overcame the limitations and the low performance of the actual scrubber systems and the negative provoked enormous environmental impact of these emissions and not complies the IMO international regulations. The method exposed in this paper overcame the requirement its international regulations of IMO (international maritime organization) and is Patent N. Pittas .
Highlights
In existing internationally installed scrubber systems, their ef iciency for sulfur binding reaches up to 90% and there is no possibility to optimize them
Huge quantities of seawater are required for cat ionisation, in order to absorb S released into the SOx form from the diesel exhaust gases with heavy fuel content of S 3.5%
Innovative system with simultaneous energy recovery in ships for complete desulphurisation of exhaust gas derived by heavy oil
Summary
In existing internationally installed scrubber systems, their ef iciency for sulfur binding reaches up to 90% and there is no possibility to optimize them. In order to reduce the droplet size order of the alkaline solution, so that the difference does not exceed two orders of magnitude, we inject at high pressure which means high droplet velocity, so as to minimize droplet size and the contact surface will increase This contact will be achieved which will result in the precipitation of the sulfur contained in SO3 and irst converted to H2SO4 and converted to Na2SO4 according to the following chemical reactions: In addition, it should be noted that the temperature of the exhaust gas varies between 450 ◦C and 430 ◦C and to reduce this temperature as much as possible to 160 ◦C, in order to increase the degree of saturation, that is to say, why the capture of S from SOx in the form of Na2SO4 or Na2SO3 a cationization scrubber process that will requires a low amount of water and not requirement large amount of water to be evaporated to further reduce the gas temperature. This means that the ship’s energy-saving and power system can function independently, if there is no need to eliminate SOx
