摘要： A nozzle, and FCC process using the nozzle for atomizing heavy feed to a riser reactor, are disclosed. A liquid feed stream is atomized by radial out-to-in impingement of atomizing vapor, discharged onto an impingement plug in an annular expansion region, then sprayed through an outlet. Baffles at the expansion region outlet, and an orifice outlet improve feed atomization and feed/FCC catalyst contact in a riser reactor. The nozzle may be used to distribute liquid over other reactor beds, or to add liquid to distillation columns.

摘要： A multi-cyclone gas/solids separator with reduced solids re-entrainment is disclosed. The separator uses a plurality of cyclones spaced horizontally apart from adjacent cyclones to process flue gas containing residual catalyst fines. Each cyclone has a body that has a feed inlet end for admitting gas and entrained solids into an annular space defined by a sidewall of the cyclone body and a cylindrical gas outlet tube axially aligned with the cyclone body. A solids outlet at an opposing end of the cyclone body has a tangential outlet for solids and a minor amount of gas through a sidewall of the cyclone body. A gas reflux opening is axially aligned with the outlet tube. The plurality of cyclones share both a common catch chamber for solids discharged from the solids outlet, and a common manifold for gas and entrained solids. A plurality of shields are positioned in the catch chamber to inhibit discharge of solids from the tangential outlet of the adjacent cyclones into a vicinity of an inlet of the gas reflux opening.
摘要翻译：公开了具有减少的固体再夹带的多旋风分离器气/固分离器。分离器使用与相邻旋风分离器水平分开的多个旋风分离器来处理含有残留催化剂细粉的烟道气。每个旋风分离器具有一个主体，该主体具有用于将气体和夹带的固体引入由旋风分离器主体的侧壁限定的环形空间和与旋风分离器主体轴向对准的圆柱形气体出口管的进料端。在旋风分离器主体的相对端处的固体出口具有用于固体的切向出口和通过旋风器主体的侧壁的少量气体。气体回流开口与出口管轴向对准。多个旋风分离器共享用于从固体出口排出的固体的公共捕获室，以及用于气体和夹带固体的公共歧管。多个屏蔽件位于捕获室中以阻止固体从相邻旋风分离器的切向出口排出到气体回流开口的入口附近。
