摘要： An apparatus and process for recovery of a carboxylic acid e.g. acetic acid, from an aqueous feed stream containing the corresponding ester, an alcohol and a small amount of water, and in some cases the carboxylic acid includes a catalytic distillation column containing an acidic catalyst and a distillation column. The alcohol is catalytically dehydrated to the corresponding ether and water, and the water reacts with the ester to generate a liquid carboxylic acid rich product stream. The acid is recovered by distillation in the distillation column. In a second embodiment, additional methanol and/or water are co-fed with the feed or fed directly to the catalytic distillation column, resulting in a liquid bottoms product stream of substantially pure acetic acid and a tops distillate stream of substantially pure ether.

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.
摘要翻译：萃取蒸馏方法，其中水溶性萃取蒸馏（ED）溶剂被再生和回收利用萃取蒸馏塔（EDC）的改进操作，使极性烃从含有极性和极性较小的烃的混合物中回收和纯化，比在ED过程中产生的预期原料和/或聚合物重。改进的方法可以在封闭的溶剂循环回路中通过温和的操作条件有效地除去和回收重质烃和/或从溶剂中除去聚合物污染物，而不需要额外的工艺能量消耗。通过改进的方法，可以消除EDC的顶部回流以进一步降低能量消耗并增强EDC上部的负载和性能，特别是当存在两个液相时。

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.

摘要： A cost effective and energy efficient distillation technique for recovering acetic acid from a waste water stream containing acetic acid and water generated during terephthalic acid production employs a liquid-liquid extraction column and a downstream dehydration distillation column that operates under azeotropic or conventional distillation conditions to recover the acetic acid. The liquid-liquid extraction column produces an extract containing extraction solvent and acetic acid which is fed to the dehydration distillation column where the extraction solvent and acetic acid are separated. The dehydration distillation column can employ a condenser system for energy recovery. The condenser system can be a steam generator that condenses vapor into a concentrated acetic acid stream and generates low pressure steam. Any remaining acetic acid in the water is treated.

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.
