The fracturing fluid backflow truck is primarily used for the treatment of fracturing backflow fluids. It separates oil, suspended solids, and water from the backflow fluids, allowing the water to be recycled or reinjected. This meets the requirements for energy conservation and environmentally friendly operations in oil fields.
The equipment consists of multiple stages of chemical and physical processes, including acid-base neutralization, chemical treatment, flotation, coagulation and sedimentation, filtration, and disinfection.
1. Adoption of Three-Phase Mixing and Separation Technology: This integrates vortex dissolved air technology and vortex mixing technology into one system. Compared to conventional pressure vessel air flotation, it reduces the amount of chemicals required and enhances treatment effectiveness.
2. Integrated and Mobile Design: The system integrates various components, including the three-phase mixer, air flotation system, high-speed drying equipment, mixing system, dosing system, filtration system, and control system, all mounted on a heavy-duty chassis. This effectively reduces the well site’s layout footprint by 20% and enables online transport and treatment, making it convenient for use in remote mountainous areas.
3. Reusability: The treated liquid phase can be reconstituted and reinjected, achieving the goal of recycling. It meets the requirements of the SY/T5329 standard.
4. Full Process Automation: The system features automated control with an intuitive visual interface, reliable performance, self-diagnosis for faults, and the capability for unattended operation. All controls are centralized in a control cabinet, allowing one person to operate the system conveniently and reliably.
