Abstract: A FLUID CATALYTIC CRACKING UNIT WHEREIN THE REACTION ZONE COMPRISES ONE OR MORE RISERS AND A REACTION VESSEL; WHEREIN CATALYST AND OIL VAPORS CONTINUALLY DISCHARGE FROM THE RISERS INTO THE REACTION VESSEL; AND WHEREIN THE REACTION VESSEL IS IN COMMUNICATION WITH A STRIPPING ZONE SUCH THAT SPENT CATALYST FLOWS INTO THE STRIPPING ZONE. IN OPERATION, A SELECTED INVENTORY OF CATALYST IS MAINTAINED IN A FLUIDIZED STATE IN THE REACTION VESSEL. SUCH SELECTED CATALYST INVENTORY IN THE REACTOR VESSEL IS MAINTAINED BY MEANS RESPONSIVE TO THE PRESSURE DIFFERENTIAL BETWEEN THE STRIPPING ZONE AND THE REACTOR VESSEL. MEANS ARE ALSO PROVIDED FOR CONTROLLING SUCH PRESSURE DIFFERENTIAL AND THEREBY ADJUSTING CATALYST INVENTORY IN THE REACTOR VESSEL.

Abstract: A VERTICAL DOWNFLOW REACTOR FOR CONTACTING A TWO-PHASE, VAPOR-LIQUID REACTION MIXTURE WITH SOLID CATALYST CONTAINED IN ONE OR MORE REACTOR VESSEL CATALYST ZONES. MEANS ARE PROVIDED IN THE UPPER PORTION OF SUCH VERTICAL RACTOR TO SEPARATE ANY SOLID PARTICULATE CONTAMINANTS FROM SAID REACTION MIXTURE PRIOR TO ADMITTING THE REACTION MIXTURE INTO A REACTOR VESSEL CATALYST ZONE. MEANS ARE ALSO PROVIDED FOR EVENLY DISTRIBUTING VAPOR AND LIQUID COMPONENTS OF THE REACTION CHARGE MIXTURE ACROSS THE HORIZONTAL CROSSSECTIONAL AREA OF A REACTOR VESSEL CATALYST ZONE.

Abstract: 1. IN A REGENERATOR FOR A FLUIDIZED CATALYST WHEREIN THE PARTICULATED CATALYST MATERIAL IS CIRCULATED WITHIN A REGENERATION COMPARTMENT HAVING VERTICAL WALLS, IN A TURBULENT FLOW BY A CARRIER GAS TO FORM A FLUIDIZED BED, AND WHEREIN THE CONDITION OF SAID FLUIDIZED BED IS REGULATED TO MAINTAIN PREDETERMINED OPERATING CONDITIONS THEREIN, THE IMPROVEMENT FOR CONTINUOUSLY MONITORING THE PRESSURE WITHIN SAID FLUIDIZED BED COMPRISING, A CONDUIT EXTENDING INTO SAID REGENERATOR COMPARTMENT AND HAVING AN OPEN END DISPOSED IN SAID FLUIDIZED CATALYST BED, THE OTHER END OF SAID CONDUIT COMMUNICATED WITH A SOURCE OF A PURGE GAS, A PRESSURE SENSING ELEMENT CONNECTED TO SAID CONDUIT, AND IN COMMUNICATION WITH SAID REGENERATION COMPARTMENT, A SHEILD DISPOSED ABOUT SAID CONDUIT OPEN END DEFINING A CHAMBER IN COMMUNICATION WITH SAID FLUIDIZED BED WHEREBY TO RECEIVE THE FLUIDIZED CATALYST AS WELL AS PURGE GAS AT THE CONDUIT OPEN END, SAID SHEILD INCLUDING A CYLINDRICAL ELEMENT HAVING A PERFORATED WALL SPACED FROM SAID CONDUIT OPEN, END, THEREBY DEFINING AN ANNULUS ABOUT THE CONDUIT, AND A SUBSTANTIALLY FLAT PERFORATED FACE PLATE AT THE END OF SAID CYLINDRICAL SHEILD ELEMENT TO DEFINE A PARTIAL CLOSURE TO THE LATTER ADJACENT TO SAID CONDUIT OPEN END, SAID FACE PLATE BEING DISPOSED IN A PLANE SUBSTANTIALLY PARALLEL TO THE VERTICAL WALLS OF SAID REGENERATION COMPARTMENT.

Abstract: A fluid catalytic cracking apparatus wherein the reaction zone comprises one or more risers and a reaction vessel. A constant inventory of catalyst is maintained in a fluidized state in the reaction vessel and catalyst is continuously withdrawn from the reaction at a rate equal to the rate catalyst enters the reaction vessel. An improved catalyst check valve connecting the reaction vessel and stripping zone controls the catalyst inventory and catalyst withdrawal rate.
