OUR LEGACY

About Vance Petro — 20+ Years Engineering Excellence in Oilfield Wastewater Treatment

Henan Vance Petroleum Machinery Co., Ltd. (Vance Petro) was founded with a singular mission: to solve the oil and gas industry's most pressing water management challenge — the safe, efficient, and cost-effective treatment of produced water and oilfield sewage.

Headquartered in Henan, China, and operating with a globally certified ISO 9001 quality management system, Vance Petro has spent more than two decades refining oilfield water treatment engineering to an exact science. Our team of 80+ specialized engineers and field technicians has designed, manufactured, and commissioned more than 500 oilfield wastewater treatment systems, serving clients across 40+ countries in the Middle East, Central Asia, Africa, Southeast Asia, South America, and beyond.

We don't manufacture generic water treatment equipment. Every system we build is engineered specifically for the extreme demands of the oilfield environment — handling oil concentrations up to 5,000 mg/L, operating across temperatures from 5°C to 95°C, and managing salinities up to 150,000 mg/L TDS (including high-brine produced water from unconventional shale operations).

PROVEN TECHNOLOGY

Our 6-Stage Oilfield Wastewater Treatment Process

From Contaminated Produced Water to Clean Effluent — Validated in 500+ Global Deployments

1

Stage 1 — Gravity Separation / API Oil-Water Separation

The first stage leverages gravity and density differential to achieve primary oil-water separation. Our API oil-water separator — designed to API 421 standards — removes free oil, floating oil films, and settleable solids from the incoming produced water stream.

Removes: Bulk free oil >150 microns
Efficiency: 60–80% oil load reduction
Temperature: 5°C to 95°C
2

Stage 2 — Chemical Dosing (Demulsifier / Coagulant / Flocculant)

Produced water often contains chemically stabilized emulsions that gravity alone cannot break. Our precision chemical dosing system injects three reagent classes in optimized sequence: Demulsifier, Coagulant, and Flocculant. Dosing rates are automatically controlled by PLC based on real-time flow and turbidity monitoring.

PLC-controlled proportional dosing
3

Stage 3 — Dissolved Air Flotation (DAF) / Induced Gas Flotation (IGF)

This is the critical polishing stage for suspended oil and fine particulate removal. Our DAF flotation unit generates millions of micro-bubbles (20–100 microns) that attach to oil droplets and suspended solids, carrying them to the surface for mechanical skimming.

Value, not waste

Stage 4 — Multi-Media Filtration

Triple-media deep-bed polishing vessels using anthracite, quartz sand, and activated carbon to achieve final target effluent quality.

Top LayerAnthracite coal — captures large particles
Middle LayerQuartz sand — removes fine suspended solids
Bottom LayerActivated carbon — adsorbs residual hydrocarbons
Result: Oil <5 mg/L • SS <20 mg/L • COD reduction >85%
5

Stage 5 — UV Disinfection / Chemical Disinfection

High-intensity UV disinfection chambers destroy bacteria, sulfate-reducing bacteria (SRB), and other microorganisms without chemical residuals. Essential for preventing microbiologically influenced corrosion (MIC) in pipelines and injection wells.

6

Stage 6 — Optional: Reverse Osmosis (RO) / Zero Liquid Discharge (ZLD)

For operators with zero-discharge mandates or maximum water reuse targets. High-pressure RO membranes reduce TDS to freshwater quality. Combined RO + thermal evaporation/crystallization achieves >95% water recovery with solid salt as the only final output.

Maximum regulatory compliance • Up to 95% water recovery

Frequently Asked Questions

Expert Answers to Your Most Important Produced Water Treatment Questions

What effluent quality can the VP-OWT Series achieve?
The Vance Petro VP-OWT Series is designed and guaranteed to achieve: Oil in water <5 mg/L (typically 2–4 mg/L), Suspended Solids <20 mg/L, COD reduction >85%, Overall oil removal efficiency >99%. These figures meet or exceed MARPOL Annex I (<15 mg/L), OSPAR, Iraqi DoE, Kazakhstani MEN, Nigerian DPR, and most other national regulations.
How quickly can a VP-OWT system be deployed and operational?
Trailer-mounted mobile units: 4–6 hours. Skid-mounted units: 6–8 hours. Containerized systems: 1–3 days for full multi-module installations. Every system leaves our factory fully assembled, piped, wired, and performance-tested.
What are the inlet conditions the VP-OWT system can handle?
Inlet oil up to 5,000 mg/L, TDS up to 150,000 mg/L, TSS up to 500 mg/L, Temperature 5–95°C, pH 5.5–9.0. For streams outside these parameters, our engineering team designs custom pre-treatment solutions.
What is the typical ROI for a VP-OWT system?
High-volume fields with truck-and-dispose operations: under 6 months (often under 90 days). Mid-size onshore: 6–18 months. Shale recycling operations: 3–12 months. We provide a free site-specific ROI analysis with every proposal.
Does the system require a civil foundation?
No. Standard configurations operate on a simple level, compacted gravel pad. No concrete foundation required. Containerized units need only standard ISO corner cast support pads.
Can the VP-OWT system treat produced water for hydraulic fracturing reuse?
Yes. For slickwater fracturing, standard treatment is typically sufficient. For crosslinked gel, we integrate partial RO or dilution. We work directly with your frac service company to meet exact specifications, enabling up to 85–100% freshwater reduction.
What after-sales support does Vance Petro provide?
24/7 technical support with direct engineer access • Remote SCADA diagnostics • On-site commissioning & training in your language • Annual service contracts • Emergency spare parts dispatched within 72 hours to major global hubs • Upgrade packages available.
