Aquatech Delivers Water Treatment to Texas Combined Cycle Power Plant
Challenge
LS Power experienced significant growth in electric demand and needed to expand its generation capacity. The company had concerns regarding capital costs, project schedule, plant reliability, and job site safety during construction. The project marked LS Power's first plant construction in 11 years, necessitating a robust solution to meet their stringent requirements. After evaluating proposals that addressed these critical issues, LS Power selected Fluor Enterprises to design, build, and commission a 620-megawatt natural gas-fired combined cycle power plant.
Aquatech was contracted by LS Power to develop a water treatment for Unit 1 expansion and was awarded the Unit 2 expansion project in 2008. This new facility will provide reliable electricity with low emissions, effectively meeting the rising demands of LS Power’s member utilities.
Solution
Aquatech was contracted for the water treatment system for Unit 1. Due to the exceptional performance of Unit 1, LS Power confidently awarded the Jack Unit 2 expansion project in 2008. This new 620-megawatt gas-fired, combined cycle facility is designed to provide reliable electricity with low emissions, meeting the increasing demands of LS Power’s member utilities.Results
For the Unit 2 expansion, Aquatech’s flow rates were increased from that of the initial Unit 1 equipment. Aquatech delivered a raw water make-up system that included the following;
- Make-up clarifier 4,000 GPM (909 m3 /hr)
- Gravity Filter, 4,000 GPM (909 m3 /hr)
Additionally, a Zero Liquid Discharge (ZLD) system was employed that included the following:
- ZLD Clarifier, 350 GPM (79 m3 /hr)
- ZLD Gravity Filter, 350 GPM (79 m3 /hr)
- Weak Acid Cation, 2 x 270 GPM (2 x 61 m3 /hr)
- HERO™, 2 x 251 GPM (2 x 57 m3 /hr)
- Forced Circulation Crystallizer, 30 GPM (7 m3 /hr)
