Unit for establishing contact between a gas and a liquid for a floating platform

A unit for establishing contact between a liquid and a gas, comprising:

• a chamber having a substantially vertical axis;
• a first series of contact sections positioned along the length of the substantially vertical axis of the chamber;
• a second series of contact sections positioned along the length of the substantially vertical axis of the chamber, alternated with the contact sections of the first series;
• a liquid circulation system adapted for circulating a liquid in the contact sections of the first series and in the contact sections of the second series in a separate manner;
• and
• connecting ducts adapted for conveying the liquid between the successive contact sections of the first series on the one hand, and between the successive contact sections of the second series on the other hand, wherein the connecting ducts are at least partially arranged outside the chamber.

A unit for establishing contact between a liquid and a gas, comprising:

• a chamber;
• a first series of contact sections disposed within the chamber including a first contact section and a second contact section, each of the first and second contact sections of the first series comprising a packing bed for promoting contact between the liquid and the gas, the first contact section of the first series being positioned above the second contact section of the first series;
• a second series of contact sections disposed within the chamber including a first contact section and a second contact section, each of the first and second contact sections of the second series comprising a packing bed for promoting contact between the liquid and the gas, the first contact section of the second series being positioned between the first and second contact sections of the first series, the second contact section of the second series being positioned below the second contact section of the first series;
• a first liquid distribution system disposed in fluid communication with the first contact section of the first series for supplying a first flow of the liquid to the first contact section of the first series;
• a second liquid distribution system disposed in fluid communication with the first contact section of the second series for supplying a second flow of the liquid to the first contact section of the second series;
• a first connecting duct extending between the first contact section of the first series and the second contact section of the first series for conveying the liquid in the first flow from the first contact section of the first series to the second contact section of the first series in fluid isolation from the first and second contact sections of the second series;
• and
• a second connecting duct extending between the first contact section of the second series and the second contact section of the second series for conveying the liquid in the second flow from the first contact section of the second series to the second contact section of the second series in fluid isolation from the first and second contact sections of the first series.
