Centrifugal decanters for petroleum oil extraction
In oilfield operations, every element of the process must be designed to withstand extreme conditions and ensure production continuity without failure. Well fluids are among the most complex materials to treat: sand, abrasive mineral particles, formation water, organic residues, and sudden compositional changes challenge any separation technology. CBB Decanters are specifically designed for the upstream oilfield, with the aim of protecting process lines, stabilizing production, and reducing operating costs related to maintenance and disposal.
Industrial process
The fluid extracted from the well is conveyed directly to the decanter, where a rapidly rotating cylindrical-conical bowl generates the centrifugal force needed to effectively separate solids from liquids even under unstable flow conditions. The internal screw, with its differential speed control, continuously extracts the solids and transfers them to the discharge, while the liquid phase is evacuated from the other side of the bowl without interrupting the process. The ability to adjust operating parameters based on the fluid’s characteristics optimizes the removal of abrasive particles, protecting downstream equipment—pumps, primary separators, and water treatment systems—from premature wear.
CBB Decanter Technology
CBB Decanters for oil extraction are designed to operate in highly critical environments, where pressure, temperature, and the presence of corrosive and abrasive materials require superior construction solutions. The bowl geometry ensures uniform sedimentation even with high-density fluids and variable solids concentrations, maintaining process continuity even under unstable operating conditions. Advanced control systems monitor torque, flow rate, and differential speed in real time, allowing the machine to automatically adapt without interruption. The use of special alloys, anti-wear treatments, and components certified for resistance to well fluids ensures high performance over time. Upstream-specific configurations also integrate solutions for energy optimization and solids management.
