Abstract: OLEFINS AND ISOPARAFFINS ARE ALKYLATED IN THE PRESENCE OF AN HF CATALYST. THE REACTOR EFFLUENT IS PASSED TO A SETTLING ZONE. THE HYDROCARBON PHASE IS FRACTIONATED TO RECOVER AN ALKYLATE PRODUCT. THE ACID PHASE IS RECYCLED TO THE REACTOR. A PORTION OF THE RECYCLED ACID IS PASSED TO A PURIFICATION COLUMN FOR REMOVAL OF ACID SOLUBLE OIL. STRIP-
PING VAPOR IS INTRODUCED INTO THE PURIFICATION COLUMN BOTH ABOVE AND BELOW THE SURFACE OF SAID SOLUBLE OIL ACCUMULATED THEREIN. BAFFLES ARE POSITIONED IN THE LOWER REGION OF THE COLUMN TO INCREASE THE VAPOR-LIQUID CONTACTING.-

Abstract: An improved fractionator and method for separating a hydrocarbon feed stream into first, second, and third component streams by passing the feed stream through an upper chamber of a vessel in indirect heat exchange relationship with separated first and second upper chambers of the vessel which are in fluid communication with a lower portion of the vessel. Said first and second upper chambers and said lower chamber have a multiplicity of spaced-apart fractionating trays extending thereacross.

Abstract: UPON SEPARATION OF AN ALKYLATION EFFLUENT FROM AN ISOPARAFFIN-OLEFIN HYDROGEN FLUORIDE ALKYLATION INTO A HYDROCARBON PHASE AND AN ACID PHASE, THE HYDROCARBON PHASE, CONTAINING ORGANIC FLUORIDES, IN CONTACTED WITH RELATIVELY PURE HF RESULTING FROM A RERUN OR PURIFACTION OF HF IN THE PRESENCE OF ISOPARAFFIN WHICH ACTS TO CONVERT AND, THEREFORE, TO REDUCE ORGANIC FLUORIDE CONTENT OF THE HF BEING RERUN. ADDITIONAL RERUN HF SUBSTANTIALLY FREE FROM OR HAVING A CNSIDERABLY REDUCED ORGANIC FLUORIDE CONTENT CAN BE USED TO FURTHER REDUCE ORGANIC FLUORIDE IN SAID HYDROCARBON PHASE.

Abstract: OLEFINS AND ISOPARAFFINS ARE ALKYLATED IN THE PRESENCE OF AN HF CATALYST. REACTOR EFFLUENT IS PASSED TO A SETTLING ZONE. THE HYDROCARBON PHASE IS FRACTIONATED TO RECOVER AN ALKYLATE PRODUCT. THE ACID PHASE IS RECYCLED TO THE REACTOR. A PORTION OF THE RECYCLED ACID IS PASSED TO A PURIFICATION COLUMN FOR REMOVAL OF ACID SOLUBLE OIL. STRIPPING VAPOR AND REFLUX LIQUID ARE PASSED TO THE PURIFICATION COLUMN TO REMOVE SUBSTANTIALLY ALL OF THE HF FROM THE ACID SOLUBLE OIL. A SUBSTANTIAL PORTION OF THE ACID SOLUBLE OIL REMOVED FROM THE PURIFICATION COLUMN IS CONTACTED EXTERNALLY WITH STRIPPING VAPOR AND REINTRODUCED INTO THE PURIFICATION COLUMN.

Abstract: IN AN ALKYLATION OF AN ISOPARAFFIN WITH AN OLEFIN, A LIGHT HYDROCARBON PHASE, E.G., A PROPANE PHASE AND AN ACID PHASE, BOTH PHASES CONTAINING ORGANIC FLUORIDE, ARE RECOVERED UPON FRACTIONATION OF THE ALKYLATION REACTION EFFLUENT, THE ACID PHASE IS CONTACTED WITH ISOPARAFFIN TO REACT OUT ORGANIC FLUORIDE, ISOPARAFFIN PHASE AND ACID PHASE ARE THUS OBTAINED, THE ISOPARAFFIN PHASE CONTAINING ALKYLATE PRODUCED FROM THE ORGANIC FLUORIDE, THE ACID PHASE NOW
CONTAINING RELATIVELY LESS ORGANIC FLUORIDE THEN BEING ADMIXED WITH THE LIGHT HYDROCARBON OR PROPANE CONTAINING PHASE, THUS REMOVING INTO THE ACID ORGANIC FLUORIDE IN SAID PHASE WHEREUPON THE ACID PHASE IS REACTED WITH ISOPARAFFIN TO PRODUCE ADDITIONAL ALKYLATE FROM THE ORGANIC FLUORIDE.-

Abstract: ALKYL FLUORIDE IN ISORARAFFIN-OLEFIN ALKYLATE PRODUCED IN PRESENCE OF HF CATALYST, E.G., AN ALKYLATE PRODUCED BY ALKYLATING ISOPARAFFIN WITH ETHYLENE AND ISOBUTYLENE OR PROPYLENE WITH AN HF CATALYST, IS CAUSED TO ALKYLATE AN ISOPARAFFIN IN THE PRESENCE OF ADDITIONAL HF ACID CATALYST BY PASSING THE ALKYLATE UPWARDLY THROUGH NOZZLES INTO A RISER-REACTOR AND AT THE NOZZLES ADMIXING WITH THE ALKYLATE OF ADDITIONAL HF ACID OF A DESRABLE KIND IN A DESIBRABLE QUANTITY TO CAUSE CONVERSION OF THE ALKYL FLUORIDE TO ADDITIONAL ALKYLATE, THE APPARATUS IN WHICH THE INVENTION IS CARRIED OUT ESSENTIALLY BEING COMPOSED OF A VESSEL HAVING A LOWER, A MID AND UPPER SECTIONS, A RISER-REACTOR CONDUIT BEING JUXTAPOSED OVER HYDROCARBON SPRAY NOZZLES IN A PARTITION BETWEEN THE LOWER AND MID SECTIONS, BUT NOT EXTENDING DOWN TO SIAD PARTITION, A SECOND CONDUIT SURROUNDING THE RISER-REACTOR CONDUIT EXTENDING FROM SAID PARTION TO AN APERTURED PARTITION BETWEEN THE MID AND UPPER SECTIONS, SIAD SECOND CONDUIT AT ITS UPPER END BEING IN SEALING ENGAGEMENT WITH SAID APERTURED PARTION AND IN REGISTER WITH THE APERTURE THEREIN, SAID RISER CONDUIT EXTENDING TO A LEVEL ABOVE SIAD APERTURED PARTION, AND DOWNCOMER MEANS FOR FLOWING ACID FROM SAID UPPER SECTION TO SAID LOWER SECTION, DOWNCOMER MEANS FOR FLOWING
HYDROCARBON FROM SAID UPPER SECTION, IN ONE EMBODIMENT, INTO A HYDROCARBON SURGE SECTION SURROUNDING SAID SECOND CONDUIT AND BETWEEN SAID PARTITIONS, AND MEANS FOR FEEDING ALKYLATE TO SAID LOWER SECTION AND FORCEFULLY UPWARDLY THROUGH SAID NOZZLES. IN ANOTHER EMBODIMENT AN ANGULAR SYSTEM COMPRISES RIGH ANGLED CONDUITS, AN ACID FLOW DIVERTER OVER HYDROCARBON PASSAGE TO DIVERT DOWN FLOWING ACID FROM AN OPENING TO PERMIT HYDROCARBON TO FLOW ESSENTIALLY HORIZONTALLY THROUGH SAID OPENING IS DESCRIBED.-

Abstract: A METHOD IS PROVIDED WHEREBY LIQUID PARAFFIN IS ACCUMULATED AND DISTRIBUTED FROM A VESSEL DIVIDED INTERNALLY BY A WEIR, SO THAT TWO DISPARATE STREAMS CAN BE MAINTAINED IN THE VESSEL WITH MIXING OF INLET MATERIALS ON ON SIDE OF THE WEIR WHILE MAINTAINING AN UNMIXED MATERIAL ON THE OTHER SIDE OF THE WIRE. IN ONE EMBODIMENT OF THE INVENTION ISOBUTANE REFLUX LIQUID IS MAINTAINED ON ONE SIDE OF THE WEIR AND OVERFLOWED INTO A SECOND ZONE WHERE IT IS MIXED WITH THE WET EFFLUENT FROM A FEED STREAM DRIER WHICH CONTAINS ISOBUTANE, OLEFINS, AND WATER. FEED WATER IS TRAPPED FROM THE MIXED STREAM AND DECANTED FROM THIS ZONE.

Abstract: A stream of vapor is continuously withdrawn from a fractionator column and passed directly to a heat exchange means in contact with the liquid in a second fractionator column. Heat is imparted to raise the temperature of the liquid in the fractionator and to condense the vapor stream withdrawn from the first fractionator. In a preferred embodiment isobutane vapor is withdrawn in a sidestream from an alkylation product fractionator and is condensed by imparting heat to the liquid in a fractionator which separates isobutane feed stock from a butane mixture wherein a controlled amount of additional heat is supplied to raise the temperature of the second fractionator sufficiently to effect separation of the mixed butane feed.

Abstract: A side draw stream from an isostripper to a debutanizer is removed from the isostripper as a liquid stream of normal butane and higher hydrocarbons. The alkylate-containing bottoms fromthe isostripper are used to indirectly heat or reboil the bottom of the debutanizer. Alkylate is recovered from the reboiler line as well as from the debutanizer.
