Distillation: processes, separatory inventions 06/06

20060137967 - Distillation systems: A differential vapor pressure (DVP) cell (150) is disposed in a divided wall column (100) that receives a feed comprising a first (102A), second (102B), third (102C) component. A separation section (120) on the feed side of the divided wall column separates the feed in a vapor comprising the first...

20060124440 - Method and apparatus to produce potable water: A method and apparatus for producing potable water from non-potable water, in which a supply of air is passed through a heating unit to increase the air temperature and then passed through an evaporative cooling media through which the non-potable water is passed in liquid/gas contact with the heated air....

20060124441 - Process for reducing the aldehyde concentration in a mixture comprising cyclohexanone and one or more aldehydes: The invention relates to a process for reducing the aldehyde concentration in a mixture comprising cyclohexanone and one or more aldehydes, said process comprising distilling said mixture in a distillation column in the presence of an alkaline compound, wherein in the bottom of the distillation column substantially no water is...

20060113179 - Method and device for producing a pure liquid from a crude liquid: When fresh water is produced from salt water or similar by evaporation of untreated or crude liquid in an evaporation device under partial vacuum and by vapour condensation in a condensation device connected with the vapour outlet of the evaporation device a high degree of evaporation and cost effectiveness can...

20060113180 - Purification of propylene oxide resulting from epoxidation of propylene with hydrogen peroxide: A process of separating a purified propylene oxide from a crude epoxidation product produced, preferably, in an epoxidation reaction of propylene with hydrogen peroxide. The process involves removing bulk water, bulk methanol, and unreacted propylene from the crude epoxidation product and thereafter subjecting the resulting propylene oxide product to extractive...
