THIRD STAGE SEPARATOR SYSTEM FOR A FLUIDIZED CATALYTIC CRACKING UNIT FOR OIL REFINING AND ITS OPERATION METHOD

摘要

P THE INVENTION RELATES TO THE SEPARATION OF CATALYST PARTICLES FROM A GAS FLOW. PARTICLES THAT HAVE BEEN SEPARATED FROM THE GAS IN A THIRD FLOOR SEPARATOR ENCLOSURE 1A ARE CONTINUOUSLY GRAVITY DOWNLOADED IN A COLLECTION HOPPER 15 CLOSED BELOW THE CONTAINER. PERIODICALLY, THE HOPPER 15 IS ISOLATED FROM THE ENCLOSURE TO ALLOW THE EMPTYING OF THE HOPPER WHILE THE PARTICLES BEING SEPARATED TEMPORARILY ACCUMULATE ON THE BOTTOM 11A OF THE CONTAINER, WHICH ENABLES CONTINUOUS OPERATION AND ENERGY SAVING. APPLICATION TO THE SEPARATION OF CATALYSTS IN A FLUIDIZED BED CATALYTIC CRACKING UNIT IN THE REFINEMENT OF HYDROCARBONS. /P
