Abstract
A method of treating effluent seawater generated in the removal of sulfur dioxide from a process gas by contacting the process gas containing sulfur dioxide with seawater, using inclined aeration and mixed auto recovery is provided. Additionally, an inclined aeration and mixed auto recovery seawater oxidation basin system for treating effluent seawater generated in the removal of sulfur dioxide from a process gas by contacting the process gas containing sulfur dioxide with seawater is provided.
Claims15
A method of treating effluent seawater generated in removing sulfur dioxide from a process gas by contacting the process gas containing sulfur dioxide with seawater comprising:
- supplying fresh seawater to a basin so that the fresh seawater flows downstream through an effluent seawater treatment system;
- supplying the effluent seawater to the basin from a flat bottom of the basin, and upstream of and adjacent to an inclined bottom of the basin, thereby providing a flow of the effluent seawater in the flow of fresh seawater;
- directing an oxidation agent at an angle of approximately 90 degrees from the inclined bottom of the basin to contact the flow of effluent seawater;
- flowing the fresh seawater, effluent seawater and oxidation agent over a first weir into a first pond;
- and
- flowing the fresh seawater, effluent seawater and oxidation agent over a second weir into a second pond prior to environmental release.
An effluent seawater treatment system for treating an effluent seawater generated in a wet scrubber in which a process gas is brought into contact with seawater for removal of sulfur dioxide from said process gas, the effluent seawater treatment system comprising:
- a basin comprising an area with a flat bottom upstream of and adjacent to an area with an inclined bottom;
- a fresh seawater supply supplying fresh seawater to an upstream head of the basin into the area with the flat bottom so that the fresh seawater flows downstream through the basin;
- an effluent seawater supply arranged at the flat bottom, and upstream of and adjacent to the inclined bottom, thereby providing an upward flow of effluent seawater into the downstream flow of fresh seawater;
- an oxidation agent supply arranged at the inclined bottom to direct an oxidation agent at an angle of approximately 90 degrees from the inclined bottom for contact with the flow of effluent seawater;
- a first weir downstream of the inclined bottom for a waterfall flow of the fresh seawater, effluent seawater and oxidation agent into a first pond;
- and
- a second weir downstream of the first pond for a waterfall flow of the fresh seawater, effluent seawater and oxidation agent into a second pond prior to environmental release.
