Alkylation utilizing surge chambers with settling chambers in a common catalyst system
Abstract
Abstract A CATALYST SEPARATOR AND A METHOD OF SEPARATING CATALYSTS ARE PROVIDED WHEREIN THE PRODUCT MIXTURE OF CATALYST AND ALKYLATE FROM TWO SEPARATE ALKYLATION REACTION ZONES USING A COMMON CATALYST ARE MAINTAINED SEPARATELY IN TWO LIQUID FULL CHAMBERS IN WHICH CATALYST IS ALLOWED TO SETTLE AND IS REMOVED FORM A COMMON OUTLET WITH MIXING OF THE CATALYST STREAMS AND RETURN OF THE MIXED CATALYST TO SEPARATE REACTION ZONES. LIQUID ALKYLATE PRODUCT OVERFLOWS FROM THE SETTLING ZONES INTO SEPARATEE SURGE ZONES SO ARRANGED IN RELATION TO THE SETTLING ZONES THAT THERE IS A CONSTANT HEAD OF LIQUID IN THE SETTLING ZONE OVERFLOWING INTO THE SEPARATE SURGE ZONES. THIS SEPARATION PREVENTS BUILD UP OF ONE OF THE ALKYLATE PRODUCTS IN THE SETTLER FROM FORCING THE ALKYLATE FROM ONE CHAMBER INTO EITHER THE CATALYST OUTLET OR INTO THE ALKYLATE PRODUCT IN THE OTHER CHAMBER OF THE SEPARATOR.
