Wastewater Treatment System for Coal-Fired Power Stations – Kentucky, USA
Context:
Sodimate supplied three identical hydrated lime dry to slurry systems for coal-fired power stations companies located in Kentucky (Louisville Gas and Electric Company (LG&E) and Kentucky Utilities (KU) at their coal-fired power stations (Mill Creek, Trimble County and Ghent) near Louisville in Kentucky (USA). ) to help them improve their environmental performance, meet their business and flow needs and comply with regulation. (LG&E serves 324,000 natural gas and 407,000 electric customers in Louisville and 16 surrounding counties. KU serves 549,000 customers in 77 Kentucky counties and five counties in Virginia.)
Sodimate equipement:
The engineers in charge of this project integrated three identical pairs of Sodimate hydrated lime dry to slurry systems (one pair of silos per site). These state-of-the-art systems include mechanical bin activators, ensuring maximum discharge efficiency, chainwheel slide gates, metering screws, injectors, 600 gallon slurry tanks and centrifugal pumps underneath the silo cones.
Sodimate supplied this identical setup for the 3 sites:
2 skirted silo, 2,700 ft3 capacity with dust collectors and radar level transmitters
2 mechanical bin activator ZDM
2 handwheel slide gates
2 metering screw DDMR
2 moisture isolation injectors
2 carbon steel slurry tanks 600 gal with stainless steel mixers
2 water supply lines with regulation valves
4 skid mounted centrifugal pumps
Performances achieved
Sodimate designed its system for a dry injection of 5 tons/day. The lime slurry is pumped continuously into a loop system at 8.07 GPM, with a concentration of 10 %.
