Ducon excels with flue gas desulfurization (FDG) systems

In today’s regulatory environment, green technologies are finding favor in the marketplace. The Obama administration has shown continued interest in reducing emissions from power plants throughout the United States.

Earlier this summer, the Environmental Protection Agency outlined proposals that could impose annual compliance costs of between $185 million and $954 million on the power industry, and could result in reductions of toxic pollutants – such as coal ash, mercury, zinc, phosphorus, and selenium – of 470 million to 2.62 billion pounds.

Ducon, which has offices in the U.S. and India – provides custom engineered equipment and systems for environmental control, power boilers, ash, coal and material handling, waste incineration, and emission monitoring for a wide variety of industries. The company serves clients in the following sectors: power, cement, pulp & paper, glass, chemical, food, steel, refineries, mining and incineration.

Ducon’s Flue Gas Desulfurization (FDG) systems remove sulfur dioxide from flue gases using a variety of reagents, such as caustic, lime, limestone, ammonia, flyash, magnesium oxide, soda ash, sea water or double alkali. The company provides systems that recover sulfur, sulfuric acid or make dry gypsum from waste product.

The technology could see more demand given the growing energy and electricity needs of both advanced and emerging markets. It also provides the market with an ability to balance the supply of power with ecological concerns. Many governments have shown environmental sensibility through new legislation and regulations aimed at controlling emissions, especially those coming from coal plants.

“We supply FGD systems along with ash and coal handling systems to the world’s coal fired power plants,” says a company spokesperson. “Ducon provides seawater and limestone FGDs.
FGD are required to control emissions of sulfur dioxide when power plans are burning coal or heavy fuel oil.”

How effective are such technologies?

Ducon has supplied wet FGD systems on over 20,000 megawatts of combined power plant capacity. The company’s technology can achieve over 99 percent sulfur dioxide removal efficiency. Its FDG systems can also recover up to 90 percent of oxidized mercury in the flue gas.
