Mercer delivers automated, enhanced-gravity separation systems purpose-built for natural-gas–fired power generation, from turbine lube-oil drainage to compressor skids, HRSG washdowns, and auxiliary equipment sumps.
INDUSTRY INSIGHT
Modern natural gas power plants operate with complex lubrication systems, thermal cycles, and high-energy components that generate oily wastewater across multiple drainage points. Lube-oil leakage from gas turbines, compressor skid drainage, HRSG and condenser washdowns, auxiliary boiler rooms, and fuel-handling areas all converge into sumps originally sized for much lower flow and solids loading.
Most facilities still rely on CPI units, corrugated packs, slotted-pipe skimmers, or simple pits that were never designed for today’s lubrication volumes or variable-flow events. When turbine fines, rust scale, and gasket debris, enter the system, these legacy separators quickly blind, stall, or short-circuit. Sheen breakthrough becomes unpredictable. Maintenance becomes weekly. Regulators take notice.
Mercer stops that cycle.
Our Compliance Master™ separators with Multi-Pack™ coalescers deliver stable droplet capture, automatic oil removal, and reliable solids evacuation, especially with rapid load swings. Natural gas facilities gain consistent discharge quality, reduced operator intervention, and documented compliance, all in a compact footprint designed for tight turbine halls and retrofit constraints.
Mercer eliminates that cycle.
Our enhanced-gravity separators with Multi-Pack™ coalescer technology deliver consistent removal of oils and solids in real time — automatically, without operator intervention, and with airtight emissions control. From aging hydro plants to modern gas turbine facilities, Mercer equips utilities with predictable separation performance, reduced labor, and compliance confidence.

INDUSTRY CHALLENGES
Treat turbine-bay drainage, gatehouse leaks, and powerhouse oily runoff while minimizing solids carry-through and protecting waterways.
Handle lube-oil leakage, compressor drainage, turbine washdowns, and sump water in highly variable flow conditions.
Remove oils and fines from coal pile runoff, conveyor/washdown water, and process-area drainage before it enters surface water or NPDES outfalls.
Manage controlled-area drainage, turbine lubricants, transformer leaks, and regulated wastewater streams with predictable, documented performance.
Capture fuel-oil spills, boiler house drainage, tank farm runoff, and oily sumps — automatically and with sealed emissions control.
Support wind, solar, and battery storage sites with containment and drainage solutions for transformer bays, inverter pads, and maintenance hubs.
Solution
Mercer brings predictable, automated performance to natural-gas fired generation by stabilizing hydraulics, controlling velocity, and removing oil and solids before they can foul downstream systems.
Mercer units capture 3× smaller droplets than simple gravity systems in a footprint typically ¼ the size of legacy separators.
Electromechanical skimming removes oil the moment it forms a layer, preventing collapse, sinking, and emulsification.
Automated sludge valves timed to solids buildup prevent accumulation of fines, metal shavings, and gasket debris.
Airtight covers reduce VOC seepage, eliminate odor issues, and keep debris out, all critical in indoor turbine settings.
Multi-Pack™ modules drop into existing vaults and pits, upgrading performance without large civil modifications.

SYSTEM PERFORMANCE
MERCER ADVANTAGE
No more hand-cranked skimmers or emergency CPI cleanouts. Mercer systems remove oil and solids continuously.
Small footprints, sealed covers, and quiet automation make Mercer ideal for turbine halls and compressor platforms.
Smaller droplet capture, fewer cleanouts, stable flow paths, CPI (Corrugated Plate Interceptors) simply can’t match it.
Airtight systems reduce operator exposure, eliminate odor, and support modern air-quality compliance.
Reduced sludge hauling, fewer outages, and improved reliability all translate to measurable savings.
Yes. Controlled-flow geometry and optimized plate spacing maintain separation when CPI units collapse.
Absolutely. Materials and coatings are selected for high-temperature performance.
Typically every 6–12 months, versus the weekly attention CPI and pits require.
Often yes. Multi-Pack™ modules drop into many existing structures with minimal modification.
Yes. Full SCADA/PLC connectivity, alarms, and telemetry are available.
Yes, especially where HRSG washdowns and condensate systems introduce variable flows and chemicals.
