摘要： A continuous epoxidation process for the production of high purity propylene oxide by the reaction of propylene with an oxidant that is a per-acid, such as peracetic acid (PAA), in a reactive distillation (RD) column. The RD column provides excellent heat integration and temperature control, and the process has the advantage of lower investment cost for capital equipment. The process operates at mild temperarures and pressures. A ferric acetylacetonate homogeneous catalyst and/or stabilizer may be included as part of the PAA feed to the process to increase PAA conversion and selectivity to propylene oxide. A pre-reactor can be incorporated upsteam of the RD column to increase the residence time at lower temperatures to enhance productivity.

摘要： A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. In particular, a rejuvenator is installed in the solvent circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. Specifically, the rejuvenator comprises 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 inside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up its contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is characterized by simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system can be operated at high efficiency and high capacity without the dreaded corrosion.

摘要： Oxidation of liquid ethanol in the presence of excess liquid ethanol and a supported oxidation catalyst provides a one step process for production of ethyl acetate. The acetic acid produced in the oxidation is absorbed by the excess liquid ethanol, which esterifies to ethyl acetate. Ethyl acetate and water is removed from the process for separation of the ethyl acetate. The oxidation portion of process is preferred with a metallic oxidation catalyst on a hydrophobic support and the esterification portion with an acidic solid ion exchange resin to promote the esterification. The process can be performed in series in separate steps, or preferably, in parallel in a single vessel, preferably a trickle bed reactor. The process is easily controlled and enables the use of a wide range of ethanol concentration as feed material.

摘要： A two-stage sealed magnetic filter continuously removes magnetic and non-magnetic contaminants from liquid process streams. Elongated non-magnetic holder sleeves (13) encasing magnet bars attract magnetic contamtnants while a screen cylinder (14) captures non-magnetic contaminants. The magnet bars are accessible without having to open the interior (30) of the housing (1) to the environment. Thus, during maintenance, removing the magnet bars from the holder sleeves releases the magnetic contaminants that have adhered to the holder sleeves into the screen cylinder which partially encloses the holder sleeves. Contaminants are flushed out of the magnetic filter without exposing workers to potentially hazardous substances. Polymeric sludge occluded with iron compounds can be effectively removed from streams in refineries and chemical plants. The iron compounds are formed from carbon steel which is prevalent in plant machinery and that corrodes in the presence of acidic contaminants.

摘要： A method for cross connecting the lean solvent supply lines between the liquid- liquid extraction. (LLE) and the extractive distillation (ED) processes thereby using the LLE column as the outlet for removing accumulated heavy hydrocarbons (HCs) and polymeric materials from the solvent loop of both processes to maintain their solvent •performance. The unique capabilities of the LLE column in rejecting heavy HCs from the solvent into a raffinate product stream that leaves the system enable the removal of the accumulated heavy i:!Cs and polymeric materials from the closed solvent loop of the ED process when their lean solvent loop are cross connected. Cross connection requires minimum equipment change. In the revamped system, the solvent recovery column (SRC) in LLE process supplies lean solvent for the extractive distillation column while the SRC of the ED process supplies lean solvent for LLE column.

摘要： An improved solvent regeneration system for extractive distillation and liquid- liquid extraction processes capable of effectively removing heavy hydrocarbons and polymeric materials that otherwise develop in a closed solvent loop. The improved process employs a light hydrocarbon displacement agent, which is at least partially soluble in the solvent to squeeze the heavy hydrocarbons and polymeric materials out of the solvent, with virtually no additional energy requirement. It has been demonstrated that the light non-aromatic hydrocarbons in the raffinate stream generated from the extractive distillation or the liquid-liquid extractive process for aromatic hydrocarbons recovery can displace not only the heavy non-aromatic hydrocarbons but also the heavy aromatic hydrocarbons from the extractive solvent, especially when the aromatic hydrocarbons in the solvent are in the C 10+ molecular weight range.

摘要： An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth. By using a high-boiling extractive distillation solvent, no solvent is entrained by the vapor phase to the EDC overhead stream, even under no liquid reflux conditions. The energy requirement and severity of the EDC can be further improved by limiting ethanol recovery in the EDC. In this partial ethanol recovery design, ethanol which remains in the aqueous stream from the EDC is recovered in a post-distillation column or the aqueous stream is recycled to a front-end pre-distillation column where the ethanol is readily recovered since the VLE curve for ethanol/water is extremely favorable for distillation.

摘要： An integrated, continuous process for transforming feedstock, e.g., reformate, which contains high levels of benzene into a low-benzene content feedstock that is suitable for gasoline blending initially removes benzene from the reformate by extractive distillation, then partially hydrogenating the high purity benzene into cyclohexane under mild conditions in a one-stage hydrogenation reactor, and thereafter recovering a cyclohexane product with high purity from the hydrogenation reactor effluent in a back- end purification step using extractive distillation. The initial or front-end separation step yields a low-benzene content reformate.

摘要： A robust, non-aqueous, and oil-soluble organic peroxide oxidant is employed for oxidative desulfurization and denitrogenation of hydrocarbon feedstocks including petroleum fuels. Even at low concentrations, the non-aqueous organic peroxide oxidant is extremely active and fast in oxidizing the sulfur and nitrogen compounds in the hydrocarbon feedstocks without catalyst. Consequently, the oxidation reactions that employ the non-aqueous organic peroxide oxidant take place at substantially lower temperatures and shorter residence times than reactions in other oxidative desulfurization and denitrogenation processes. As a result, a higher percentage of the valuable non-sulfur and non-nitrogen containing components in the hydrocarbon feedstock are more likely preserved with the inventive process. Desulfurization and denitrogenation occur in a single phase non-aqueous environment so that no phase transfer of the oxidant is required.
