Heater Effects on Cyclone Performance for the Separation of Solids from High Temperature and Pressure Effluents

摘要: A 25.4-mm diameter hydrocyclone with an underflow receiver was evaluated for its ability to achieve separation of fine particles from water at elevated temperatures and pressures relevant supercritical oxidation. Temperature varied 25°C 340°C, while pressure maintained 27.6 MPa. The studied were α-alumina. Particle-removal efficiency affected by the capabilities hydrocyclone, deposition on heater surface, flocculation particles. Particle-size distributions suspended solids analyses confirmed that cyclone, controlled (densityparticle − densitywater)/viscositywater ratio. Because this ratio is sensitive temperature, especially in neighborhood point, efficiencies sharply increased temperature. Contrary traditional air cyclone theory, removal inversely correlated flow rate. This result caused particle flocculat...
