Water Treatment Chemicals
OVERVIEW
From drilling mud make-up to steam-assisted gravity drainage (SAGD) and produced-water reinjection, the quality of your water circuit determines uptime, energy intensity, and licence-to-operate. Poorly treated water scales heat exchangers, poisons catalysts, inflates chemical spend and triggers non-compliance notices. Conversely, a well-designed treatment train can:
-
Boost heat-transfer efficiency 10–15 % in once-through steam generators
-
Cut fresh-water withdrawals by 60 % via high-recovery membrane loops
-
Shave OPEX USD 0.40–0.90 per barrel by trimming chemical overdosing
-
Deliver zero-liquid-discharge (ZLD) footprints that satisfy stringent EPA and IMO rules
Water-Treatment Capabilities Across Projects
From drilling mud make-up to steam-assisted gravity drainage (SAGD) and produced-water reinjection, the quality of your water circuit determines uptime, energy intensity, and licence-to-operate. Poorly treated water scales heat exchangers, poisons catalysts, inflates chemical spend and triggers non-compliance notices. Conversely, a well-designed treatment train can:
| Filter group | What you can select | Typical options |
|---|
| 1. Treatment Technology | Unit operations and hybrids that target particulates, TDS, organics or microbes |
• Coarse & walnut-shell filtration • Dissolved Air Flotation (DAF) • Membrane: UF / NF / RO, ceramic MF • Ion exchange / softening • Thermal: MED, MVC, crystalliser • Chemical: oxidation, scale & corrosion programs • Biological: MBBR, O&G-adapted MBR |
| 2. Project Type & Environment |
Hydrocarbon asset class and water origin | • Land-rig produced water • Shale flowback & produced water • Offshore fixed platform or FPSO • Deep-water HP/HT • Oil-sands (SAGD, CSS) • Refinery utilities & effluents |
| 3. Performance Metrics |
Economic and technical benchmarks for ease of ops. | • Recovery % at design flow • $/bbl treated (CAPEX amortised + OPEX) • Specific energy (kWh · m-³) • Chemical dose (mg · l-¹) • Availability / mean time between CIP |
| 4. Regulatory& Env Impact | Jurisdiction-specific discharge limits and ESG variables | • USEPA 40 CFR Part 435 / 437 • IMO MARPOL Annex V • OSPAR produced-water target (≤ 30 mg · l-¹ oil-in-water) • Local groundwater reinjection standards • Corporate Scope 1 & 2 water-intensity KPIs |
Technology Winners by Environment
| Environment | Highest-scoring primary train | Typical polish step | Why it scores best |
|---|---|---|---|
| Onshore shale (high TDS, high organics) | High-pressure RO with anti-scalant + nano-bubble floatation | Activated carbon + UV-C | Handles 160 000 ppm TDS; modular skids trailer-mount overnight; chemical footprint low |
| Offshore FPSO (space-limited) | Compact ceramic UF + media filtration | Cartridge coalescer | Ceramic membranes tolerate CIP with hypochlorite; small footprint & weight |
| Deep-water HP/HT | H₂S scavenger + topside crystalliser (MVC) | Sulphate-removal nano-filter | Delivers ZLD to meet zero-overboard mandates; MVC copes with 130 °C brine |
| Oil-sands SAGD | F-type evaporator + VDU blow-down recycle | Ion exchange softening | Generates 98 %-pure distillate for OTSG; steam quality ↑ 20 %; eliminates lime softeners |
