Design of a Novel Fracturing Flowback Fluid Separation Device

Abstract

To address the problems associated with traditional fracturing flowback fluid separation devices, such as reliance on manual operation and low separation efficiency, this paper presents the design of a novel automatic separation device based on a combination of gravity settling and multi stage filtration. The device adopts a multi chamber structure to successively achieve sand settling, filtration, and oil water separation, with automatic discharge of oil, water, and sand achieved through level sensors and gate control systems, enabling continuous operation. The internal flow field was simulated using ANSYS Fluent with a multiphase flow model to verify the feasibility and effectiveness of the separation process. The results indicate that the device can effectively improve separation efficiency, reduce manual intervention and operating costs, and shows promising engineering application prospects.
