The Brine Concentrator/Demineralizer project is located at the Orlando Utility Commission (OUC)/Southern Power Stanton Energy Center, a 900-megawatt 2 x 1 combined-cycle power plant. This expansion of generation capacity prompted the need for an expansion to the existing water and wastewater treatment facilities to serve the existing plant and the new unit.
The existing facilities allowed for treatment of 1000 gallons per minute (GPM), which was increased by 500 GPM thanks to the brine concentrator and crystallizer system installed by PCL. The team’s scope of work included the field fabrication of a 20-foot-diameter Inconel 625 alloy sump and insertion of a 10-foot-diameter, 105,000-pound heater into the sump. The team also installed the brine concentrator, crystallizer, and supporting equipment in the existing brine treatment area.
The client also required an increase in the supply of boiler feed water. To accomplish this, PCL’s project team installed a new 300 GPM ecodyne demineralized water system. Installation of the skids that comprise this system necessitated expanding the existing water treatment building and the separation of the potable water distribution system from the service water distribution system.
The instrument and electrical scope performed by PCL’s team included installation of two 6.9 KVA transformers and SUS systems, eight motor control centers, and associated switchgear.
