ADA-ES, an Advanced Emissions Solutions company, has signed a definitive agreement to license ClearChem Technology, a patented furnace sorbent injection technology to control sulfur dioxide emissions from coal-fired boilers.
The addition of ClearChem Technology expands ADA’s product lines for emissions compliance and provides an integrated product to meet the Mercury and Air Toxic Standards and other EPA regulations, the company says.
ClearChem Technology injects a specially prepared reagent of sub-micron sized particles, commonly calcium carbonate, directly into a boiler or furnace. It provides fuel flexibility to burn a wider range of coals, enhances flue gas desulfurization (FGD) capabilities and works in conjunction with other control technologies such as dry sorbent injection systems.
ClearChem Technology has proved successful in multiple full-scale boiler trials, the company says, and ADA has additional customer demonstrations planned.
In November, URS said full-scale testing of its emissions control technology at a Midwestern power plant demonstrated greater than 85 percent mercury (Hg) removal and greater than 98 percent sulfur trioxide (SO3) removal, upstream of the plant’s wet scrubber. The new process is based on URS’ SBS Injection sorbent injection technology for control of SO3 emissions from power plants.
