Novinda AS-HgX Shows Superior Hg Capture in Dry-Scrubbing Environment

Category:Case Studies | Mar 28, 2014

In numerous field trials over the past two years Novinda Corporation has demonstrated efficient and effective mercury capture from flue gas at dry-scrubbed plants burning PRB coal. These trials were conducted at plants equipped with both Spray Dryer Absorbers (SDAs) and Circulating Dry Scrubbers (CDSs). Some units had selective catalytic reactors for NOx control. Particulates were captured either in fabric filters or electrostatic precipitators. Novinda's Amended Silicates AS-HgX was injected upstream of the dry scrubber device to capture mercury from the flue gas. The AS-HgX was removed in a downstream particulate control device and subsequently recycled along with the scrubber solids and fly ash.


Novinda Product Shows Efficient Hg Capture in High SO3 Environment

Category:Case Studies | Apr 11, 2013

In a recent field trial Novinda Corporation demonstrated efficient and effective mercury capture of mercury from the flue gas at a plant burning Eastern bituminous coal. The trial was conducted at Santee-Cooper’s Winyah station Unit 4 in South Carolina. The host unit is equipped with a selective catalytic reactor (SCR) followed by parallel electrostatic precipitators (ESP) and wet flue gas desulfurization (FGD) modules. Novinda’s Amended Silicates (AS) mercury reagent was injected to capture mercury from the flue gas before it entered the wet FGD. Tests were run with and without simultaneous injection of hydrated lime. The host unit burns a medium sulfur eastern bituminous coal yielding a concentration of 20 ppm SO3 at the point of AS injection.
