摘要： A process to reduce flush circulation rates in an adsorption separation system is presented. The flush stream is used to improve the capacity of the simulated moving bed system by flushing the contents of the transfer lines containing raffinate material back into the adsorbent column. The flush stream is a material that is used to flush the head chambers in the column, or from the rotary valve flush dome sealant.

摘要： A process for the production of olefin sulfonates is presented. The process comprising generating olefins from normal alkanes through a dehydrogenation unit to produce a mixture of alkanes and alkenes. The mixture is sulfonated to react the olefins and generate olefin sulfonates. The olefin sulfonates are separated from the normal alkanes to produce a product stream, with the normal alkanes recycled to the dehydrogenation unit.

摘要： One exemplary embodiment can be a separation system. The separation system can include an adsorption zone, a rotary valve, a transition zone, and one or more pipes. Usually, the transition zone includes one or more lines communicating the rotary valve with the adsorption zone. The rotary valve alternatively may distribute an input of a feed or a desorbent to the adsorption zone or alternatively can receive an output of a raffinate or an extract from the adsorption zone in a line, and a remnant may remain in the line from a previous input or output. One or more pipes outside the transition zone communicating with the rotary valve can form at least one pipe volume receiving an input for dislodging a remnant or for receiving a remnant from the line. The remnant may be different from the input or output.

摘要： A process to increase the capacity of the adsorbent in a normal paraffin adsorption separation system is presented. A tertiary flush stream is used to improve the capacity of the simulated moving bed system by flushing residual raffinate from the feed transfer line. The flushing removes residual raffinate containing desorbent that competes with the adsorption of normal paraffins from the feedstream. The flush stream is a material that will displace fluid in the column, but will not enter the pores of the adsorbent.

摘要： Processes and apparatuses are provided for producing a normal paraffin product or a substantially linear paraffin product from a feed including normal hydrocarbons, non-normal hydrocarbons, and contaminants. The contaminants are extracted from the feed through contact with an ionic liquid stream to form a clean stream of hydrocarbons. The desired hydrocarbons are selectively adsorbed from the clean stream of hydrocarbons with a molecular sieve to remove the desired hydrocarbons from the non-desired hydrocarbons. A desorbent recovers the desired hydrocarbons from the molecular sieve. Then the desired hydrocarbons are separated from the desorbent to yield the normal paraffin product.

摘要： A simulated moving bed adsorptive separation process for preparing the separate feed streams charged to naphtha reforming unit and a steam cracking unit has been developed. The feed stream to the overall unit is passed into the adsorptive separation unit. The desorbent in the adsorptive separation is C12 hydrocarbons. The simulated moving bed adsorptive separation separates the components of the feed stream into a normal paraffin stream, which is charged to the steam cracking process, and non-normal hydrocarbons which are passed into a reforming zone. The desorbent is readily separated from the normal paraffin stream and from the non-normal paraffin stream and the simulated moving bed adsorption zone is operated at an A/Fn ratio of from about 0.90 to about 0.92.

摘要： A process is disclosed using a new catalyst for use in the alkylation of benzene with a substantially linear olefin. The catalyst allows for cation exchange with a rare earth element to increase the alkylation of benzene, while reducing the amount of isomerization of the alkyl group. This is important for increasing the quality of the alkylbenzene by increasing the linearity of the alkylbenzene.

摘要： A process is presented for the selective separation and recovery of large normal paraffins from a heavy kerosene boiling point fraction. The process includes passing the heavy kerosene fraction through an adsorption separation system for separating the normal paraffins from the paraffin mixture. The recovered extract and raffinate streams are mixed with a diluent made up of a lighter hydrocarbon. The subsequent diluted extract and raffinate streams are passed through first fractionation columns to separate the desorbent from the diluent and the heavier paraffins. The mixture of the diluent and heavier paraffins is passed through a second set of fractionation columns to separate the diluent and the heavier paraffins.
