摘要： In a process for the fractional distillation of a liquid crude aldehyde mixture including straight-chain and branched aldehydes, the product mixture is fractionated in a first distillation column to give a product stream of branched aldehyde, a product stream of straight-chain aldehyde and a further product stream including straight-chain aldehyde and the high boiling constituents. The further product stream is then fractionated in a second distillation column whose packing volume is a factor of from 50 to 200 smaller than that of the first distillation column to give a product stream of straight-chain aldehyde and a high boiler product stream.

摘要： A system for separating products from reactants within a reactive distillation column is revealed. Reaction products heavier than reactants are discouraged to re-enter the reaction zone by a rectifying section in between the reaction zone and the stripping section. Reaction products lighter than reactants are discouraged to re-enter the reaction zone by a stripping section in between the reaction zone and the rectifying section.

摘要： In a method for distilling (meth)acrylic acid and/or (meth)acrylic ester, the method has the step of uniformly distributing a supply liquid in a distillation tower over an entirety of a horizontal cross sectional area in the distillation tower. A distillation apparatus for distilling (meth)acrylic acid and/or (meth)acrylic ester in a distillation tower has a supply element for supplying the supply liquid into the distillation tower. The supply element is formed with at least two supply ports through which the liquid is supplied into the distillation tower.

摘要： Upgrading of a hydrocarbon feed containing sulfur, metals, and asphaltenes involves applying the feed to a distillation column for producing a substantially asphaltene-free, and metal-free fraction and a non-distilled fraction containing sulfur, asphaltenes, and metals. At least some of the substantially asphaltene-free, and metal-free distillate fraction is converted to a hydrogen donor diluent. The non-distilled fraction is processed in a solvent deasphalting unit for producing a deasphalted oil stream and an asphaltene stream. After a combined stream is formed from the hydrogen donor diluent and the deasphalted oil stream, the combined stream is thermally cracked forming a thermally cracked stream that is applied to the distillation column. Also, an apparatus for upgrading a hydrocarbon feed containing sulfur, metals, and asphaltenes, the apparatus comprising: a distillation column for receiving the feed and producing a substantially asphaltene-free, and metal-free distillate fraction and a non-distilled fraction containing sulfur, asphaltene and metals; and means for producing a hydrogen donor diluent from at least some of the substantially asphaltene-free, and metal-free distillate fraction. The apparatus also includes a solvent deasphalting unit for processing the non-distilled fraction and producing a deasphalted oil stream and an asphaltene stream and combining the hydrogen donor diluent with the deasphalted oil stream to form a combined stream; and a thermal cracker for thermally cracking the combined stream and forming a thermally cracked stream whereby the thermally cracked stream is applied to the distillation column.

摘要： A fractionator has a fractionation vessel, a reactor effluent vapors inlet, a vapor feed contacting zone, a baffled contacting section above the vapor feed contacting zone, a tops section above the baffled contacting section, a heavy bottoms liquid hold-up pool section below the vapor feed contacting zone, a bottoms outlet, a bottoms recycle system with a heat exchanger. Recycled, cooled bottoms is fed back to the fractionation vessel at the heavy bottoms liquid hold-up pool section and above the vapor feed contacting zone. The improvements involve providing a separation tray and downpipe for separating cooler bottoms liquid from hotter product vapors within the fractionation vessel: to avoid condensation and absorption of product vapors by the liquid pool; to have more rapid and uniform quenching of hot liquid entering the pool; and substantially reduce costly onstream maintenance to clean fouled bottoms recycle exchangers.
