Contacting of fluids

Claim 2

AN ALKYLATION PROCESS WHICH COMPRISES INTRODUCING A MIXTURE OF ISOPARAFFIN AND OLEFINIC HYDROCARBONS INTO THE LOWER PORTION OF A REACTION ZONE CONTAINING A SETTLED LIQUID ACID CATALYST PHASE IN ITS LOWER PORTION, THEREIN DIVIDING THE MIXTURE INTO A PLURALITY OF STREAMS AND COMMINGLING EACH OF SAID STREAMS WITH A SEARATE STREAM OF LIQUID ACID CATALYST, JETTING THE RESULTANT MIXED STREAMS UPWARDLY THROUGH VENTRUI-SHAPED PASSAGEWAYS COMMUNICATING WITH SAID SETTLED CATALYST PHASE, THEREBY CREATING AN EDUCTOR EFFECT IN THE LOWER PORTION OF THE REACTION ZONE, MOVING LIQUID ACID CATALYST UPWARDLY FROM SAID SETTLED PHASE THROUGH SAID VENTURI-SHAPED PASSAGEWAYS BY SAID EDUCTOR EFFECT, PASSING THE ADMIXED HYDROCARBONS AND CATALYST UPWARDLY WITHIN THE REACTION ZONE AND REACTING THE OLEFIN WITH THE ISOPARAFFIN IN THE PRESENCE OF THE CATALYST, THEREAFTER SEPARATING THE CATALYST FROM THE REACTED HYDROCARBONS AND RETURNING THE SAME BY GRAVITY TO THE LOWER PORTION OF THE REACTION ZONE.

Claim 3

A CONTACTING APPARATUS FOR FLUIDS WHICH COMPRISES IN COMBINATION, A VERTICALLY DISPOSED HOUSING, AN OPENENDED CYLINDRICAL BAFFLE POSITIONED CONCENTRICALLY WITHIN AND SPACED FROM THE INNER WALL AND ENDS OF SAID HOUSING, A TRANSVERSE BAFFLE EXTENDING ACROSS THE LOWER END OF SAID CYLINDRICAL BAFFLE AND HAVING A PLURALITY OF SPACED OPENINGS THERETHROUGH, EACH OF SAID OPENINGS HAVING A VENTURISHAPED PASSAGEWAY MEANS CONNECTING THEREWITH, FLUID INLET MEANS THROUGH THE LOWER PORTION OF SAID HOUSING HAVING FLUID DISTRIBUTING MEANS CONNECTING THEREWITH POSITIONED BELOW SAID TRANSVERSE BAFFLE, SAID DISTRIBUTING MEANS HAVING A PLURALITY OF OUTLET NOZZLES THEREFROM, WITH A NOZZLE BEING DIRECTED INTO EACH OF SAID PLURALITY OF OPENINGS AND VENTURI PASSAGEWAYS OF SAID TRANSVERSE BAFFLE WHEREBY FLLUID RECIRCULATION WITHIN SAID HOUSING IS ENHANCED, ADDITIONAL FLUID INLET MEANS TO THE LOWER PORTION OF SAID HOUSING AND CONDUIT MEANS CONNECTING FROM SAID INLET MEANS TO EACH OF THE PLURALITY OF OUTLET NOZZLES AND SAID DISTRIBUTING MEANS, AND CONTACTED FLUID OUTLET MEANS FROM SAID HOUSING AT AN ELEVATION ABOVE THE LFOWER END OF SAID CYLINDRICAL BAFFLE.

Claim 4

A CONTACTING APPARATUS FOR FLUIDS WHICH COMPRISES IN COMBINATION, A VERTICALLY DISPOSED HOUSING, AN OPENENDED CYLINDRICAL BAFFLE POSITIONED CONCENTRICALLY WITHIN AND SPACED FROM THE INNER WALL AND ENDS OF SAID HOUSING, A TRANSVERSE BAFFLE EXTENDING ACROSS THE LOWER END OF SAID CYLINDRICAL BAFFLE AND HAVING A PLURALITY OF SPACED OPENINGS THERETHROUGH, EACH OF SAID OPENINGS HAVING A VENTURISHAPED PASSAGEWAY MEANS CONNECTING THEREWITH, FLUID INLET MEANS THROUGH THE LOWER PORTION OF SAID HOUSING HAVING FLUID DISTRIBUTING MEANS CONNECTING THEREWITH POSITIONED BELOW SAID TRANSVERSE BAFFLE, SAID DISTRIBUTING MEANS HAVING A PLURALITY OF OUTLET NOZZLES THEREFROM, WITH A NOZZLE BEING DIRECTED INTO EACH OF SAID PLURALITY OF OPENINGS AND VENTURI PASSAGEWAYS OF SAID TRANSVERSE BAFFLE WHEREBY FLLUID RECIRCULATION WITHIN SAID HOUSING IS ENHANCED, ADDITIONAL FLUID INLET MEANS TO THE LOWER PORTION OF SAID HOUSING AND CONDUIT MEANS CONNECTING FROM SAID INLET MEANS TO EACH OF THE PLURALITY OF OUTLET NOZZLES AND SAID DISTRIBUTING MEANS, AND CONTACTED FLUID OUTLET MEANS FROM SAID HOUSING AT AN ELEVATION ABOVE THE LFOWER END OF SAID CYLINDRICAL BAFFLE.
