Advantages |
Disadvantages |
Summary |
| Sea water (for open loop) | 1: Reliable technology and simple process for operation 2: Easily available sea water 3: Less equipment invest cost 4: No consumption of fresh water | 1: Larger scrubber required 2: Extra CO2 discharge 3: Not suitable for exhaut gas with high SOx 4: Large occupying space and low desulfurization efficiency in low salty sea water 5:Depending on the sea water alkalinity 6: Produced more effluent | 1: Simple structure and cheap cost 2: Applicable to the sea where discharge effluent can be allowed |
| Fresh water +NaOH (close loop or Hybrid) Hybrid- can be realized by one touch control beteen open loop and close loop | 1: Not relying on the condition of sea water 2: High desulfurization efficiency 3: Less CO2
| 1: Consuming fresh water 2: Requiring dosing system 3: Requiring cooling system 4: NaOH is required to be stored safely | 1:High equipment cost 2: Better stability |
| Sea water + Mg(OH)2 (close loop or Hybrid) Hybrid- can be realized by one touch control beteen open loop and close loop
| 1: Not relying on the condition of sea water 2: Better desulfurization efficiency than sea water 3: Less alkaline required 4: Can be easily and safely stored and transforted | 1: Requiring dosing system 2: Requiring cooling system
| 1: High equipment cost 2: Better stability 3: Harmless to the body |
