Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
IN A PROCESS IN WHICH AN ALKYLATABLE HYDROCARBON IS REACTED WITH AN OLEFIN IN THE PRESENCE OF A CATALYST THE METHOD OF IMPROVING THE SEPARATION OF CATALYST AND CATALYST ESTERS FROM THE REACTION ZONE EFFLUENT WHICH COMPRISES INTRODUCING THE EFFLUENT INTO A SETTLING ZONE WHEREIN SAID EFFLUENT SEPARATES INTO A HYDROCARBON-RICH PHASE AND AN ACID-RICH PHASE, PASSING THE HYDROCARBONRICH PHASE AT A LOW VELOCITY THROUGH A FIRST WIRE COALESCING MAT WHEREBY CATALYST AND CATALYST ESTER DROPLETS NOT NORMALLY SEPARATED BY SETTLING ARE COALESCED AND REMOVED, SEPARATELY WITHDRAWING THE ACID AND HYDROCARBON PHASE FROM THE SETTLING ZONE, TRANSFERRING THE HYDROCARBON PHASE TO A SECOND ZONE AND PASSING SAID HYDROCARBONS THROUGH A SECOND WIRE COALESCING MAT AT A HIGHER VELOCITY WHEREBY ADDITIONAL DROPLETS OF CATALYST AND CATALYST ESTERS ARE REMOVED.

Claim 3
Dependent Claim
138 words
A COALESCING DEVICE SUITABLE FOR REMOVING IMMISCIBLE ALKYLATION CATALYST AND CATALYST ESTERS FROM A HYDROCARBON FLUID IN A FLOWING STREAM OF SAID HYDROCARBON FLUID, SAID ALKYLATION CATALYST AND SAID CATALYST ESTERS, WHICH COMPRISES A PLURALITY OF MATS SPACED APART AND DISPOSED TRNSVERSELY ACROSS THE FLOW PATH OF THE STREAM, THE SPACE BETWEEN SAID MATS OCCUPIED BY GLASS WOOL, EACH OF SID MATS FORMED OF A PLURALITY OF SMALL WIRE DIAMETER, LARGE MESH WIRE SCREENS LONGITUDINALLY SPACED APART ALONG SAID FLOW PATH, THE WIRES OF SAID SCREENS NONALIGNED, THE WIRE OF SAID SCREENS OF A DIAMETER BETWEEN ABOUT 0.001 AND 0.1 INCH, THE MESH OF SAID SCREENS FROM ABOUT 5 TO ABOUT 50 TIMES THE DIAMETER OF SAID WIRE, SAID SCREENS SPACED APART BY A DISTANCE OF FROM ABOUT 3 TO ABOUT 30 TIMES THE DIAMETER OF SAID WIRE.
