    摘要： A continuous online process for rejuvenating whole stream contaminated lean sulfolane in an extraction system is provided. A rejuvenator is installed in the solvent: circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. The rejuvenator includes a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed outside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system operates at high efficiency and high capacity without the dreaded corrosion.

    摘要： The invention disclosed relates to a process for refining a hydrocarbon feed to make substantially styrene-free C6-C8 aromatic hydrocarbons (BTX). The hydrocarbon feed, for example, unhydrotreated pyrolysis gasoline, is distilled to make a BTX rich stream containing styrene which is fractionated to separate C6 and C7 hydrocarbons from C8 hydrocarbons including styrene. Styrene in the C8 hydrocarbons reacts in the presence of a selective etherification catalyst with a C1-C3 lower alkyl alcohol to form the corresponding styrene ether, which is then separated by distillation into a styrene ether stream and a C8 hydrocarbons rich stream. The C8 hydrocarbons rich stream is then re-mixed with the C6 and C7 hydrocarbons, and sent to hydrogenation reactors to remove sulphur and olefinic hydrocarbons to form substantially styrene-free BTX.

    摘要： Deasphalted residual oil (DAO) and the aromatics-rich extract that is derived from DAO have low polycyclic aromatics contents, relatively low aniline points, and high flash points. They form blending stocks that improve properties of mixed feedstocks to consistently produce environmentally qualified rubber processing oil (RPO) by extraction under low solvent-to-oil ratios and moderate extraction temperatures. Distilling a petroleum crude oil under atmospheric pressure generates a bottom residual oil which is then subject to vacuum distillation to yield a bottom residual oil. DAO is produced by removing the asphalt from the vacuum bottom residual oil through extraction with light paraffinic solvent. The extract of DAO is a co-product in the production of the bright stock of the lubricating oil through extraction. The feedstock is mixed with the extract from a petroleum fraction boiling in lube oil range. Liquid-liquid counter-current extraction yields a raffinate stream; removal of solvent therefrom produces the RPO.

    摘要： Extractive distillation processes whereby water-soluble extractive distillation (ED) solvents are regenerated and recovered employ improved operations of the extractive distillation column (EDC) so that polar hydrocarbons are recovered and purified from mixtures containing polar and less polar hydrocarbons and measurable amounts of hydrocarbons that are heavier than intended feedstock and/or polymers that are generated in the ED process. The improved process can effectively remove and recover the heavy hydrocarbons and/or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein.

    摘要： A novel method for connecting multiple existing columns which are retrofitted into vapor-liquid contacting devices with trays or packings suitable for the operation of a three-phase (vapor-liquid-liquid) extractive distillation column for aromatics recovery. The retrofitted columns are connected by a vapor transfer line to transfer the vapor phase from the top of the lower column to the bottom of the upper column, and by a liquid transfer line to transfer the liquid phase from the bottom of the upper column to the top of the lower column of the three-phase extractive distillation column. One improvement is the feeding of the ascending vapor from the top of the lower column to below the liquid level in the bottom of the upper column as the aeration/mixing driving force and/or in combination of the installation of a jet mixer to prevent phase separation, which is deemed to occur at the bottom of the upper column, wherein a bulk quantity of liquid is maintained without mixing in order to provide the hydraulic head for the bottom liquid transfer pump. The jet mixer, if installed, uses the bottom liquid from the upper column or the extractive solvent feed as the jetting liquid to provide the necessary mixing to homogenize and disperse the two liquid phases in the bottom of the upper column. Experimental data is disclosed for verifying the existence of two liquid phases in the three-phase extractive distillation column.
