Explore our precision-fabricated membrane concentration arrays, zero liquid discharge skids, and ultra-high-pressure DTRO packages built to OEM/ODM specifications.
Navigating complex upstream petrochemical effluent streams requires far more than generic membrane filtration. It demands full-spectrum process engineering designed around extreme chemical and physical variability.
Produced water and hydraulic fracturing flowback fluids frequently exhibit total dissolved solids (TDS) ranging from 35,000 mg/L to well over 220,000 mg/L. Uncontrolled ionic concentrations of barium (Ba²&spplus;), strontium (Sr²&spplus;), calcium (Ca²&spplus;), and silicate ions precipitate instantaneously upon pressure or pH shifts, destroying standard reverse osmosis spacers within hours.
Free, dispersed, and chemically emulsified crude oils, combined with polyacrylamide (PAM) friction reducers and biocides, create impenetrable boundary layers on polyamide thin-film composite membranes. Our systems deploy specialized coalescence, induced gas flotation (IGF), and organoclay media to guarantee free oil content below 5 mg/L.
When brine concentrations exceed osmotic pressure barriers of 70 bar, standard spiral-wound elements experience catastrophic feed-spacer channel clogging. Our disc-tube reverse osmosis (DTRO) modules operate up to 120–160 bar, utilizing open-channel hydraulic geometry with high-frequency shear to eliminate concentration polarization.
How Shanghai Tongjie combines deep petrochemical metallurgy, component integration, and modular manufacturing to deliver 40%–60% CAPEX savings without sacrificing engineering tolerances.
Produced water containing several hundred thousand mg/L chlorides coupled with hydrogen sulfide (H&sub2;S) and carbon dioxide (CO&sub2;) rapidly corrodes conventional 304 or lower-grade stainless steels. Our Shanghai production facilities house automated orbital welding, passivation baths, and specialized helium leak-testing rigs for exotic alloys.
High-pressure manifolds, valve bodies, and pump wet-ends are specified in Super Duplex 2507 (PREN ≥ 42) or Titanium Grade 2, completely immunizing components against pitting and crevice corrosion.
All piping spools undergo 100% radiographic (RT) or dye-penetrant (PT) testing to comply with international high-pressure vessel standards and offshore vibration criteria.
Site installation in remote oilfields (e.g., the Permian Basin, GCC deserts, or West Siberia) incurs massive field labor costs. We fabricate complete produced water treatment systems inside ISO-certified, thermally insulated, blast-resistant shipping containers equipped with HVAC, gas detection, and automated fire suppression.
Every system undergoes full-load hydraulic, electrical, and control loop verification with synthetic brine before leaving Shanghai, compressing site commissioning to less than 15 days.
While skid structures, pressure vessels, and automation cabinets are built in-house, we seamlessly integrate world-class tier-1 pumps (Danfoss, Cat Pumps), membranes (DuPont, Toray), and PLCs (Siemens, Allen-Bradley).
International EPC contractors, oil majors, and industrial concession holders operate under stringent commercial and operational risk matrices. Here is how our ODM manufacturing model directly de-risks capital equipment investments.
| Procurement Pain Point | Legacy Industry Standard | Tongjie Engineered ODM Solution | Direct Operational Benefit |
|---|---|---|---|
| Prolonged Equipment Delivery Lead Times | Western/European OEMs quote 36–54 weeks due to subcontracted fabrication bottlenecks. | Vertically integrated fabrication with in-house structural, piping, and assembly bays delivering in 12–18 weeks. | 60% Faster Project Commercialization |
| Unscheduled Downtime from Membrane Scaling | Standard spiral RO elements fail within 1–3 months in produced water with TDS > 50,000 mg/L. | High-shear DTRO and STRO modules featuring wide open-channel flow patterns that eliminate feed spacer fouling. | Membrane Lifespan Extended to 3+ Years |
| High Deep-Well Disposal Costs (SWD) | Trucking millions of barrels of water to commercial saltwater disposal wells ($1.50–$3.50/bbl). | On-site modular container systems recovering up to 85% clean water for hydraulic fracturing reuse or reinjection. | Disposal Cost Cut by 70%–80% |
| Explosive / Hazardous Environment Demands | Standard industrial components requiring expensive retrofits to meet field safety codes. | Fully engineered skids built to ATEX, IECEx, and NEC Class 1 Division 1 or Division 2 explosion-proof standards. | Seamless Wellhead & Battery Integration |
| Post-Delivery Support & Spare Parts Lock-In | Proprietary consumables priced at exorbitant markups with slow international dispatch. | Open-architecture mechanical design utilizing universal standard consumables and guaranteed spare parts dispatch. | OPEX Consumables Savings of > 45% |
From digital twin remote optimization to hybrid thermal-membrane concentration, the produced water sector is transitioning from simple disposal to high-value industrial resource recovery.
Modern upstream operators operate unmanned or minimally staffed well pads. Our produced water packages feature native edge computing PLCs connected to cloud diagnostic dashboards. Machine learning algorithms continuously monitor trans-membrane pressure (TMP), differential pressure (ΔP), and feed temperature to trigger automated Clean-in-Place (CIP) sequences before irreversible scaling occurs.
Operating high-pressure pumps at 90–140 bar requires massive electrical input. We integrate isobaric pressure exchangers (PX) and turbochargers directly into our DTRO skid manifolds. By recovering up to 96% of the hydraulic energy from the high-pressure concentrate stream, we slash specific energy consumption to under 3.5–4.8 kWh per cubic meter of treated water.
Where environmental discharge mandates zero liquid discharge (ZLD), thermal evaporation alone is prohibitively expensive. Our hybrid process train utilizes DTRO to concentrate the brine up to 140,000–180,000 mg/L TDS, slashing the volumetric burden on downstream Mechanical Vapor Recompression (MVR) evaporators and crystallizers by 75%.
Engineered configurations tailored to regional geologies, regulatory regimes, and environmental extremes across major global hydrocarbon basins.
Rapid treatment of high-volume fracturing return fluid containing friction reducers and suspended clays. The system delivers clarified, softened brine ideal for blending next-generation slickwater fracs, avoiding expensive freshwater acquisition.
Operating reliably in 55°C ambient temperatures. High-temperature RO and deoxygenation modules strip dissolved O&sub2; to ≤ 10 ppb and remove sulfate ions to prevent wellbore reservoir souring and barium sulfate plugging during EOR water flooding.
