FCC Friction Reduction With Cyclone Separator Energy Of Experiments

As heavy oil FCC technologies, when asked to cyclone separator separation efficiency at the same time, guaranteed to try to reduce its resistance losses, has reached the purpose of energy-saving friction reduction. This subject adopts experimental method of different structural parameters, under the guide vane cyclone separator resistance character and the internal flow field measurement and analysis. Draw the side seam can guide cone to enhance the efficiency of separation, but diversion cone to a certain extent it would increase the system pressure drop. Only add appropriate seam the diversion area is open, can guarantee cone structure doesn't improve system pressure drop at the same time, still can increase the separation efficiency. Experiments also confirm the separation space can improve efficiency increase reduced pressure drop. Through the analysis of the internal flow field obtained after the diversion cone, tangential velocity peak as open and decrease of seam area than smaller, kinetic energy loss has also changed little, system to produce turbulent can chance to smaller. But the less than open seams area to a certain degree, kinetic energy loss and get bigger, experimental concluded that the ratio of three or so in the least, kinetic energy loss system minimal pressure.Through to cut streaming cyclone separator entrance of adding baffle structure resistance character, flow field research and performance test, analyze the structure of the paddle efficiency factors and cause increased resistance losses of reason, performance testing get separation factor it also proves a single paddle structure bring pressure drop is far greater than rising efficiency loss. But for future cut streaming cyclone separator entrance structure change friction reduction of experimental research provides a basis.
