The primary cyclone is further provided with a gas outlet conduit at its upper end fluidly connected to one or more secondary cyclone separators, which secondary cyclone separators are positioned in the space between the centrally positioned primary cyclone and the wall of the reactor vessel and which secondary cyclones have means to discharge solids to the lower end of the reactor vessel and means to discharge a gaseous stream poor in solids to a gas outlet of the reactor vessel. The primary cyclone is further provided with a primary stripping zone at its lower end and means to discharge pre-stripped solids from the primary cyclone to the lower end of the reactor vessel. The reactor vessel further comprises at the lower end of reactor vessel a secondary stripping zone is and means to discharge stripped solids from the reactor vessel.

摘要： A fluid catalytic cracking unit includes a nozzle located in the bottom of a riser reactor. A first conduit provides a passageway for enabling a dispersing gas to flow therethrough and through an outlet passageway in a cap covering the end of the conduit. The outlet passageway discharges the dispersing gas into a liquid hydrocarbon feed material flowing through a second conduit spaced from and enclosing the first conduit to form an annulus therebetween, thereby providing a passageway for enabling the liquid hydrocarbon feed material to flow. A second cap covers the end of the second conduit and is spaced from the first cap thereby forming a mixing zone therebetween for mixing the liquid hydrocarbon feed and the dispersing gas. The second cap includes a continuous circular slot as an outlet passageway of the first cap and is adapted for discharging the mixture of liquid hydrocarbon feed and the dispersing gas. Hot regenerated catalyst enters the riser bottom region through a regenerator standpipe.
摘要翻译：流化催化裂化装置包括位于提升管反应器底部的喷嘴。第一导管提供通道，用于使分散气体能够流过其中并且穿过覆盖导管末端的盖中的出口通道。出口通道将分散气体排放到流过与第一导管隔开并包围第一导管的第二导管的液态烃进料中，以在其间形成环形空间，由此提供用于使液态烃进料流动的通道。第二盖覆盖第二导管的端部并且与第一盖隔开，从而在其间形成混合区域以混合液态烃进料和分散气体。第二盖包括作为第一盖的出口通道的连续圆形槽，并且适于排出液态烃进料和分散气体的混合物。热再生催化剂通过再生器立管进入提升管底部区域。
