Dibasic Acid (DBA)

Many utilities have chosen wet limestone scrubbing as the process of choice for flue gas desulfurization (FGD). INVISTA's organic diacids are additives which can significantly enhance this process. Both Adi-pure® high purity adipic acid and Dibasic Acid (DBA) are available to meet the user's needs.

Operators of coal-fired boilers want FGD systems that are reliable, are based on proven technology, and meet environmental regulations at optimal power generation cost. Utilities, technology vendors and architect/engineering firms are discovering that organic additives improve SO₂ removal efficiency and offer a wide range of possible benefits including:

• Equipment downsizing of new scrubber units

• Reduced investments in scrubber retrofits

• Lower operating expense through
  • reduced L/G ratio in wet scrubbers
  • less power consumption by slurry pumps
  • reduced limestone consumption
  • reduced sludge volume
  • consumption of less expensive coal

• Increased generating capacity

• Less maintenance costs through reduced scaling and gas exit corrosion

• Improved ability to handle swings in inlet SO₂

• Accumulation of additional SO₂ credits for use or sale
