选用新型旋风分离器消除装置瓶颈

SELECTING NEW TYPE CYCLONE ELIMI- INATING THE BOTTLENECK FROM UNIT

杭州炼油厂在对催化裂化装置再生器改造中,应用了新型BY型旋风分离器,与原型号相比,BY型旋风分离器具有直径小、处理量大、效率高等特点。在主风量满足的前提下,装置处理量提高到300～380kt/a,每吨原料催化剂单耗降低了0.5kg,降低了生产成本,改善了周围环境,而且大大减少了对旋风分离器的冲刷及磨损,为装置长周期运行创造了条件,消除了装置瓶颈,为企业带来了可观的经济效益。

The new type BY type cyclone was applied on the regenerator reformation of FCC unit in Hang Zhou refinery. By comparison with original cyclone, the BY type cyclone had the features of small diameter, large treatment capacity and high efficiency. Under the prerequisite of satisfactory main air capacity, the treatment capacity increased to (30-38) × 104 t/a, the individual consumption of catalyst decreased by 0. 5kg, the production cost was reduced, the surrounding environment was improved, the washout and wear of cyclone was greatly reduced. The condition of long period operation for unit was created, the bottleneck was eliminated from unit, and the obvious economic benefit of enterprise was obtained.
