Centrifugal decanters for oil refining
In petroleum refining, the quality of solid-liquid separation directly impacts the efficiency of process units and the useful life of equipment. The treated streams often contain critical characteristics—fine particulates, spent catalysts, heavy residues, and highly viscous compounds—requiring decanter centrifuges capable of responding with precision and continuity. CBB Decanter designs dedicated refining solutions that combine high performance, resistance to petroleum fluids, and optimized operating costs.
Industrial process
The material to be treated is fed into the rotating cylindrical-conical drum, where centrifugal force rapidly separates the solid and liquid phases, effectively overcoming challenges related to high viscosity or the presence of fine and dispersed particles. The internal screw conveyor transfers the solids to the discharge outlet at a calibrated differential speed to ensure maximum removal efficiency, while the clarified product is extracted continuously and in a controlled manner. Adjusting the operating parameters allows for the compositional variations typical of different refinery streams, maintaining consistent separated product quality and reducing the load on downstream processing units.
CBB Decanter Technology
CBB Decanters for oil refining handle flows characterized by high density, significant abrasiveness, and variable composition depending on the processing phases. The optimized bowl geometry ensures uniform sedimentation even with heavy fluids, while the scroll profile is designed to handle solids in a controlled manner without interrupting the operating flow. Advanced control systems adjust torque, flow rate, and differential speed in real time, automatically adapting the machine’s behavior to process conditions. The use of high-strength alloys and anti-wear treatments specifically designed for petroleum products reduces plant downtime and optimizes long-term maintenance costs.
