Product Overview
The Yukos Continuous Acid Mixing Equipment is an advanced, fully automated solution engineered for the continuous online preparation and precise concentration control of stimulation fluids. Designed to eliminate premixing time and reduce chemical waste, this system enables real-time blending of Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and various liquid/dry additives directly during field operations.
Integrated System Architecture
Acid Feeding System: Heavy-duty chemical pumps ensure precise acid intake and stable delivery.
Water Supply System: High-capacity centrifugal pumps provide continuous and reliable base-fluid supply.
Multi-Stream Additive Injection: Precision metering pumps support liquid additives (3–6+ streams) and dry additives (1–2 streams) for accurate dosing.
High-Shear Online Mixing Unit: Ensures fast and uniform acid blending before downhole injection.
Intelligent Control & Discharge: Supports Auto/Manual/Remote operation with integrated high-pressure pumping manifolds.
Features
Premium Corrosion-Resistant & Harsh-Environment Design
Advanced Metallurgy: Fluid ends, valves, and piping manifolds are lined or constructed with high-grade, acid-resistant materials to withstand concentrated HCl/HF. Robust Sealing Robust Sealing Structures: Mechanical seals, acid-resistant gaskets, and reinforced connections in pumps, valves, and manifolds prevent acid leakage under high-pressure HCl/HF operations, improving safety and HSE compliance.
Oilfield Intelligent Control System
Supports Automatic, Manual, and Remote Operation modes. Real-time digital monitoring and data logging of flow rates, chemical dosage, mixing density, and discharge pressure, easily integrating with your overall fracturing command center.
Flexible Mobility & Chassis Options
Available in Skid-Mounted, Truck-Mounted, or Semi-Trailer configurations tailored to global road regulations and terrain challenges. Chassis Partners: Sinotruk, MAN, Mercedes-Benz, SHACMAN. Power Packs: CAT, Cummins, Detroit Diesel.

Frequently Asked Questions
Q: What corrosive chemicals can this system safely handle?
A: The fluid end and pumping components are specifically engineered to handle high concentrations of Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), Mud Acid, organic acids, and associated highly corrosive oilfield stimulation additives.
Q: Can the equipment be customized to meet local explosion-proof (HSE) standards?
A: Yes. We offer fully customized electrical, control, and lighting systems compliant with regional explosion-proof ratings (such as ATEX, IECEx, or Class I Div 1/2) depending on your operational destination.
Q: What kind of commissioning and after-sales support do you provide for international buyers?
A: Yukos provides comprehensive lifecycle support, including field installation guidance, on-site commissioning, operator training, and an uninterrupted global supply chain for spare parts.
Q: What is the standard lead time for a customized manufacturing order?
A: Our standard production lead time ranges from 60 to 90 days depending on the customization complexity and specific truck chassis sourcing requirements.
Q: Do you provide a Certificate of Compliance and third-party inspection (TPI) reports?
A: Yes, we fully support and welcome international third-party inspections by SGS, BV, or Intertek, providing complete material traceability and test logs before shipment.
Q: How does the system ensure dosing accuracy for highly viscous liquid additives?
A: The system utilizes positive displacement metering pumps integrated with closed-loop flowmeters to dynamically adjust injection rates regardless of fluid viscosity fluctuations.
Q: What specific anti-corrosion coating standard do you apply to the external structure?
A: We use a multi-layer marine-grade epoxy coating system compliant with ISO 12944 C5-M standards to ensure long-term protection against harsh salt spray and desert oilfield environments.
Q: Can the data logs from the control system be exported to third-party data platforms?
A: Yes, our intelligent control systems support standard Modbus, CAN-bus, or RJ45 communication protocols for seamless real-time data streaming to client databases.
Q: Are your high-pressure discharge manifolds certified for specified pressure ratings?
A: All high-pressure manifolds are fully assembled, non-destructively tested, and pressure-tested up to 1.5 times the working pressure in compliance with API 6A standards.
Q: What is the standard warranty period for the complete acid mixing unit?
A: We provide a 12-month comprehensive warranty starting from the date of site commissioning or 18 months from the port of departure, whichever comes first.
Q: Do you maintain a critical spare parts inventory for rapid international dispatch?
A: Yes, we stock standard acid-resistant seals, pump fluid ends, and electronic sensors ready for emergency air-freight shipping to minimize field downtime.
