Abstract: Process and apparatus ensure high on-stream reliability of a complex that requires a heat pump which is using a compound having a high boiling point, such as xylenes. When the compressor is shutdown, it can be isolated from the distillation column and receiver while the column is allowed to continue to operate with an auxiliary reboiler for constant heat input. The heat pump can be started up and heated to the normal process temperature, so that when the heavy vapor is charged to the heat pump, it does not immediately condense into liquid, causing damage to the compressor.

Abstract: Processes for the recovery of aromatic hydrocarbons from one or more vent gas streams associated with an aromatic complex. The vapor streams are passed to an absorption zone in which an aromatic-selective solvent absorbs the aromatics. The aromatic-selective solvent can be processed along with other solvent extraction streams within the aromatic complex. The absorption zone may be a portion of an existing vessel or column, such as an extractive distillation column or a stabilizer.

Abstract: A process for separating xylene from a feedstock in which the feedstock is separated into a xylene stream, a benzene rich stream and a light ends stream. Two separation zones may be utilized in which liquid from both is sent to a stabilization zone and the vapor from the stabilization zone is combined with a stream prior to the stream entering the second separation zone.

Abstract: Methods and systems are provided for producing a desired xylene isomer. The method includes adsorbing the desired xylene isomer from a mixed xylene stream in an adsorbent chamber. The desired xylene isomer is desorbed with a desorbent to produce an extract stream with the desired xylene isomer and the desorbent, where the desorbent has a lower boiling point than the desired xylene isomer. The extract stream is fractionated in an extract fractionator to produce a low pressure extract overhead stream with gaseous desorbent. The low pressure extract overhead stream is pressurized to produce a high pressure extract overhead stream with a temperature greater than an extract reboiler temperature. The high pressure extract overhead stream is condensed in an extract process reboiler, and produces a liquid extract overhead stream.

Abstract: Purge fluid from a vessel head in an adsorption process is distributed to recovery processes according to the purity of product contained in the fluid. Extract-rich fluid thus is routed directly to recovery of the extract product. Distribution preferably is determined by internal positioning of feed, desorbent and product streams in the adsorption vessel.

Abstract: A process according to various approaches includes flushing an intermediate transfer line between a raffinate stream transfer line and a desorbent stream transfer line away from the adsorptive separation chamber to remove residual fluid including desorbent from intermediate transfer line. The process may include directing the residual fluid flushed from the intermediate transfer line to a recycle stream to introduce the residual fluid into the adsorptive separation chamber.

Abstract: Methods and apparatuses for separating toluene from multiple hydrocarbon streams are provided. A method includes fractionating a first hydrocarbon stream, which includes benzene-depleted fractionation bottoms from benzene fractionation, in a first fractionation zone into a first fractionation overhead stream that includes toluene and a first fractionation bottoms. A second hydrocarbon stream, which includes toluene and is substantially free of compounds having a higher vapor pressure than toluene, is fractionated in a second fractionation zone into a second fractionation overhead stream including toluene and a second fractionation bottoms. The second fractionation zone is in liquid isolation from and in vapor communication with the first fractionation zone. The first fractionation bottoms are removed from the first fractionation zone, and the second fractionation bottoms are removed from the second fractionation zone separate from the first fractionation bottoms. The first fractionation overhead stream and the second fractionation overhead stream are combined to produce a combined fractionation overhead stream.
