Over the past several decades there have been immense improvements in process chemistry, a better understanding of materials, simplified designs, and other technological enhancements. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO₂) from exhaust flue gases of fossil-fuel power plants and the emissions of other sulfur dioxide-emitting processes. SO₂ is now being removed from flue gases by a variety of methods:

• Wet scrubbing
• Spray-dry scrubbing
• Wet sulfuric acid process recovering sulfur in the form of commercial quality sulfuric acid
• Wet SNOX Flue gas desulfurization
• Dry sorbent injection systems

Scrubbers are a highly efficient and reliable means of removing SO₂, particulate matter, hydrochloric acid, and other air toxins. Scrubbers have been utilized for 25 years, yet some individuals might not be aware of the advancements that a quarter-century of ongoing enhancements has produced. In the past few years numerous technical enhancements to scrubbers have occurred in such areas as reliability, cost, waste prevention, and energy consumption. The fact is the air pollution control business is highly competitive, so it is aggressive and cost-conscious. Moreover, research and development, as well as demonstrations and comprehensive testing, are currently in progress.

There is a common prejudice that scrubbers are unreliable. Early scrubber systems used to have certain issues and some of them were fairly unreliable. However, recent experience at individual utilities confirms that wet scrubbers now are very reliable, with availability over 99% in many cases, often close to 100 percent. Some believe that scrubbers don’t reach sufficient SO₂ removal effectiveness, but in reality scrubbers are very efficient air pollution control devices and can remove more than 95% of the SO₂ from power plant stack emissions. SO₂ removal efficiencies often are as high as 98% to 99%.

Wet scrubbers are capable of removing significant quantities of particulate matter and chlorine gas. Independent industry experts have concluded that retrofitted SO₂ scrubbers can remove a high percentage of particulate matter from flue gases and nearly all the hydrochloric acid (HCl) from stack emissions.

Additionally, there is an entrenched misconception that scrubber systems cost too much. Technological advances, increased experience, and flexible regulations have contributed to significant declines in the capital and operating costs of scrubbers relative to historic values. Modern funding models have been created that lessen or remove the capital expenses incurred by the utility.financing schemes have been devised which reduce or eliminate the capital costs borne by the utility.

Wet scrubbers are effective air pollution control devices. Numerous factors are taken into account during design to ensure efficient functioning of the scrubbing system. Most commonly, a wet scrubber consists of a vessel, ductwork, fan, mist eliminator, pumps, and liquid treatment.

If you are looking for the best air treatment device to improve air quality, Redwood Technology offers a cutting-edge type of wet scrubber – a Multi-Vortex wet air scrubber.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
