Abstract: A system for alkylating hydrocarbons which includes an improved method of safely handling alkylation catalyst is disclosed. The process includes passing the alkylation catalyst from a settler vessel to a catalyst receiving vessel, via a catalyst cooler, for containment therein in the presence of a condensible gas. Also disclosed is a method for controlling the pressure in the catalyst receiving vessel by controlling the rate of removal of vapors.

Abstract: A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon phase contained in an alkylation settler by contacting the hydrocarbon phase with an HF containing stream, containing greater than about 80 wt. % and less than about 94 wt. % HF, in the intermediate portion of the settler which contains at least one tray system, with each tray system comprising a perforated tray defining a plurality of perforations and a layer of packing below the perforated tray, are disclosed.

Abstract: A process for alkylating isobutene by introducing a feed containing isobutene and an isoparaffin, in the form of droplets, into an acid catalyst to produce an alkylation product, wherein the Sauter mean diameter of the droplets is greater than or equal to about 150 ?m and is less than or equal to about 500 ?m, is disclosed.

Abstract: One exemplary embodiment can be a barrier for a leak escaping from an alkylation unit. The barrier can include a plurality of members positioned proximate to at least one surface of a vessel in the alkylation unit. Generally, the plurality of members includes at least one first member spaced apart from the at least one surface, and at least one second member distinct from the at least one first member spaced apart from the at least one surface. Typically, the second member has at least a portion closer to the at least one surface than the at least one first member.

Abstract: A system for increasing the isobutane to olefin ratio in an alkylation process/system is disclosed. The system includes provisions for charging a portion of the settler effluent as a feed to at least one reaction zone downflow from the first reaction zone of a multi-zone alkylation reactor along with a portion of the olefin feed to the multi-zone alkylation reactor.

Abstract: A method is disclosed for removing water from an alkylation process system using a water removal column to remove water from a re-run column (catalyst regeneration column) overhead stream.

Abstract: An improved condenser system employing heat exchange tubes that are supported by rod-type baffles. The condenser system can be a reflux condenser positioned at the top of a distillation column and employing a generally upright U-tube bundle for cooling fluids exiting the top of the distillation column.

Abstract: An improved apparatus useful in a process for separating a liquid stream (which can be an HF catalyst mixture) having a first liquid component (which can be HF), a second liquid component (which can be light ASO) and a third liquid component (which can be heavy ASO) is disclosed. The apparatus includes a closed vessel including an upper portion, a lower portion, and an intermediate portion, and above a bottom tray contained therein having a downcomer extending downwardly therefrom. The apparatus also includes a conduit located within the downcomer and opening below the level of the bottom tray.

Abstract: Described is a process for separating sulfone from a hydrocarbon having a small concentration of said sulfone by use of water as an extraction solvent.

Abstract: Disclosed is an alkylation process which utilizes a mixture of sulfone and hydrogen fluoride as an alkylation catalyst. The process provides for the removal of light ASO from the alkylation catalyst that accumulates therein as a result of the inability to remove the light ASO produced as a by-product of the alkylation reaction.

Abstract: Disclosed is an alkylation process which utilizes a mixture of sulfone and hydrogen fluoride as an alkylation catalyst. The process provides for the removal of ASO and water from the alkylation catalyst that accumulates therein while minimizing the loss of sulfone and HF with the ASO and water removed.

Abstract: Disclosed is an alkylation process which utilizes a mixture of sulfone and hydrogen fluoride as an alkylation catalyst. The process provides for the regeneration of an alkylation catalyst having ASO therein by separating HF from the ASO and sulfone components. The ASO and sulfone are thereafter separated to provide sulfone which is substantially free of ASO.
