Abstract: The gas-liquid separation under high pressure is studied by a large-scale industrial cyclone separator and numerical simulation method is used to analyze the flow field distribution within cyclone separator under high pressure.The structure of cyclone separator is modified through arranging perforated plates at different positions in the cyclone separator and installing a baffle at the inlet position.The separation performances before and after arranging perforated plate are compared.The simulation results show that the symmetrical inlets facilitate the symmetrical distribution of the flow field.Perforated plates and baffle both can improve the separation efficiency in the separator.After a comprehensive improvement,the cyclone separator can separate completely the droplets with particle size larger than 5 μm without increasing pressure loss of the separator,and the separation efficiency of the droplets with particle size less than 5 μm increases 24.60%.
