Plant Daniel’s scrubber project reached its most significant milestone to date when flue gas was sent through the new stack to test the process on Wednesday.
The first gas was sent through unit 1 at approximately 8 a.m.
“This milestone is the culmination of more than three years of planning, construction and testing,” said Engineering Manager Jay Weston. “The scrubber is another sign of our commitment to providing environmentally responsible energy to our customers.”
Now that testing has started, a noticeable water vapor plume will be visible from the top of the scrubber stack. The plume is caused by warm water vapor from the wet scrubber process condensing when it mixes with the cooler atmosphere.
“The plume is not harmful,” Weston said. “In fact, the scrubber is reducing emissions from the plant and will improve air quality overall.”
When it begins operating, the scrubber will remove approximately 95 percent of sulfur dioxides and other substances from Plant Daniel’s unit 1 and 2 emissions.
The project is scheduled to be completed by April 2016 to be in compliance with federal regulations.
