Abstract
The present invention provides a process for the absorption of sulfur dioxide from flue gases comprising the steps of: a) providing input seawater or brackish water; b) treating at least a portion of the seawater or brackish water to form a more concentrated solution of ions; and c) contacting the flue gas with an aqueous stream containing the concentrated solution to form flue gas with a reduced content of sulfur dioxide and a wash solution. wherein the treatment in stage (b) is a process selected from the group consisting of vacuum distillation, distillation, reverse osmosis, or any combination thereof.
Claims15
A process for the absorption of sulfur dioxide from flue gases comprising the steps of:
- a) providing input seawater or brackish water;
- b) treating at least a portion of said seawater or brackish water to form concentrated seawater or brackish water having a higher than normal concentration of bicarbonate/carbonate ions;
- and
- c) contacting said flue gas with an aqueous stream containing said concentrated seawater or brackish water to form flue gas with a reduced content of sulfur dioxide and a wash solution.
- wherein said treatment in stage (b) is a process selected from the group consisting of vacuum distillation, distillation, reverse osmosis, or any combination thereof.
