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： 公开了一种喷嘴和使用喷嘴将FCC的原料雾化到提升管反应器的重质进料。 液体进料流通过雾化蒸气的径向向内冲击雾化，排放到环形膨胀区域中的冲击塞上，然后通过出口喷射。 膨胀区出口处的挡板和孔出口改善了提升管反应器中的进料雾化和进料/ FCC催化剂接触。 喷嘴可以用于将液体分配到其他反应器床上，或者将液体添加到蒸馏塔中。
