20060157336 - Dividing-wall column with feed in whole or in part in the vaporous state and/or side stream take off in whole or in part in the vaporous state: A dividing-wall column having a dividing wall which is essentially disposed along the long direction of the column is proposed, which divides the column interior into a feed part, a take off part, an upper shared column part and a lower shared column part, with feed in whole or in...

20060157338 - Distillation process: An improved method for efficiently adding additional heat values into a distillation process to optimize the production of distillate from water....

20060157337 - Energy efficient method and apparatus for exothermic reactions: An energy efficient process scheme for a highly exothermic reaction-distillation system in which the reactor is external to the distillation column and the feed to the reactor comprises a mixture of at least one liquid product stream from the distillation column with or without other liquid/vapor reactants. The reactor is...

20060151309 - Method for the rectifying separation of liquids containing (meth)acrylic monomers in a rectification column: In a process for rectificatively separating liquids comprising (meth)acrylic monomers in a rectification column, a stream is withdrawn from the rectification column and recycled into the rectification column as a molecular oxygen-enriched liquid phase....

20060151310 - Method for the distillative separation of a mixture containing vinyl ether and alchol: a) passing the mixture into a first distillation column and withdrawing, as a top product, an azeotrope containing vinyl ether (I) and alcohol (II) and, as a bottom product, a stream enriched with the alcohol (II); b) passing the azeotrope containing vinyl ether (I) and alcohol (II) from the first...

20060144686 - Apparatus and method for handling easily polymerizable substance, apparatus for extracting liquid from apparatus under reduced pressure, and process for producing easily polymerizable substance: In an apparatus capable of distilling and refining an easily polymerizable substance, piping is performed so that when a strainer in action is switched to a backup strainer, the strainer can be switched after removing air in the backup strainer to replace air in the backup strainer with a discharge...
