Seawater FGD
In the seawater flue gas desulphurization (FGD) process, sulfur compounds are eliminated from the exhaust emissions of power plants in coastal areas.Â
This innovative technology uses the cooling water circuit downstream of the condenser to purify the gas via a seawater counter-current.
OUCO seawater FGD systems feature an open spray tower technology and a packed tower design. All this translates into low operating and maintenance costs, as well as no by-products.Â
This option is perfect for eco-friendly and resourceful establishments.

Seawater FGD is a reliable and efficient method in removing sulfur dioxide from flue gases in power plants and businesses.
The natural alkalinity of saltwater then neutralizes it before being released into the environment (the carbonate-related system).
Below are the features of Seawater FGD:
- Â Â Removes sulfur dioxide
- Â Â Simple, chemical-free operation
- Â Â Alkalinity from seawater (pH 8.0-8.5) instead of chemicals
- Â Â Q-pack packing provides excellent removal efficiency and low pressure drop.
- Â Â Seawater FGD uses the least electricity.
- Â Â No sludge; aerated water discharged
- Â Â Minimal restrictions and low investment costs
We minimize our environmental effect by removing Sulphur Dioxide before releasing the flue gas into the air.
- Â Â Only seawater and air are needed.
- Â Â No reagents or chemicals.
- Â Â Less expensive to build and operate than other FGD systems.
- Â Â The absorbed SO2 is converted to a nontoxic sulfate ion.
Scrubbing sulfur dioxide with a cold sodium sulfite solution yields a sodium hydrogen sulfite solution.
Heating the solution reverses the reaction, forming sulfur dioxide and sodium sulfite solution.
Flue gas desulfurization (FGD) or scrubbers remove sulfur from exhaust gases with efficiency ranging from 50% to 98%.
Wet scrubbers usually remove more, whereas dry scrubbers remove less.
The SO2 absorber is the core of seawater FGD.
The mist eliminator reintroduces the flue gas-borne drops into the operation.
The clean gas exits the absorber and goes to a cooling tower or wet stack.
The method has two major stages:
- Â Â Removal of SOx (HCl, HF)
- Â Â Treatment of the absorber effluent
The flue gas is brought into intense contact with saltwater in the absorption zone to remove sulfur oxides (SOx) and other acidic components (HCl, HF).
The seawater absorption zone is gaseous with air before returning to the sea to ensure segregated SO2 to sulfate.
The absorption zone seawater is gassed with air before returning to the sea to ensure sulfite oxidation.
