Separation of a dispersed liquid hydrocarbon phase from an immiscible liquid phase

Claim 1

A PROCESS OF SEPARATING TERTIARY AMYLENES FROM A HYDROCARBON MIXTURE CONTAINING SAID TERTIARY AMYLENES AND OTHER C5 HYDROCARBONS WHICH COMPRISES CONTACTING SAID MIXTURE WITH AN AQUEOUS SULFURIC ACID IN AN ABSORPTION ZONE, SAID AQUEOUS SULFURIC ACID HAVING AN ACID CONCENTRATION IN THE RANGE OF 50-70 WEIGHT PERCENT, MAINTAINING THE TEMPERATURE OF SAID ABSORPTION ZONE BELOW 100*F., PASSING A SECOND MIXTURE COMPRISED OF IMMISCIBLE HYDROCARBON AND SULFURIC ACID PHASES FROM SAID ABSORPTION ZONE TO A CONTACT ZONE, CONTACTING SAID SECOND MIXTURE IN SAID CONTACT ZONE WITH A PORTION OF SAID IMMISCIBLE LIQUID HYDROCARBON WITHDRAWN FROM A SEPARATION ZONE SUFFICIENT TO PRODUCE A THIRD LIQUID MIXTURE COMPRISED OF A SULFURIC ACID PHASE DISPERSED IN AN IMMISCIBLE HYDROCARBON PHASE, PASSING SAID THIRD MIXTURE FROM SAID CONTACT ZONE TO SAID SEPARATION ZONE, WITHDRAWING FROM SAID SEPARATION ZONE SAID IMMISCIBLE LIQUID HYDROCARBON, AND WITHDRAWING FROM SAID SEPARATION ZONE A SULFURIC ACID PHASE CONTAINING ABSORBED TERTIARY AMYLENES.
