A hydrocyclone is a specifically designed facility following the enhanced gravity separation principle. A typical hydrocyclone can build up gravity fields of 2000-3000g. The key design parameters are often determined according to specific applications. In general, as shown in Fig.3, a typical de-oiling hydrocyclone

In de-foulant hydrocyclone (DFH), reducing the energy consumption can improve the overflow kinetic energy to suck and flush away the foulants at underflow. In this study, a conical surface (CS) is inserted near the locus of zero vertical velocity (LZVV) to control the turbulence intensity of DFH. We investigated the effects of different sizes ...
