| 6998026 | Method for producing tertiary C-C-alkyl esters of (meth)acrylic acid A tert-C4–C8-alkyl (meth)acrylate is prepared by reacting (meth)acrylic acid with an olefin of the formula where R1 and R2, which may be i... | 02/14/2006 |
| 6887345 | Process and device for evaporating liquids, for example black liquor from cellulose cooking, which contain solid and dissolved substances The present invention relates to a process and a device for evaporating liquids, for example black liquor from cellulose cooking, which contain solid and dissolved substances which are to be concentrated. The liquid is heated to close to boiling temperature in a hea... | 05/03/2005 |
| 5837096 | Falling film evaporator A falling film evaporator includes a shell with a number of heat transfer elements within the shell. Each heat transfer element has two opposed essentially rectangular plates joined together along upright sides and along seams substantially parallel to th... | 11/17/1998 |
| 4925526 | Tube-type evaporator A falling film evaporator having vertical outer tubes with closed upper ends connected to an upper tube plate disposed in the lower region of the evaporator. Other parallel tubes are disposed inside the outer tubes and are connected to a lower tube plate ... | 05/15/1990 |
| 4325781 | Co-current evaporator In a vessel (1), several mutually parallel evaporator tubes (2) are arranged which, on their outside, are surrounded by heating steam introduced into the interior (1a) of the vessel. A coaxial displacement body (3) is arranged in the interior of the evapo... | 04/20/1982 |
| 4309243 | Vertical tube distillers In a new type of evaporator both a stream of cooling liquid and vapor are produced simultaneously. The cooling liquid is then used to compress and condense the vapor in an ejector-condenser. Heat of vaporization is recaptured in the ejector-condenser and ... | 01/05/1982 |
| 4216002 | Selective condensation process and condenser apparatus Contaminant substances having high biochemical oxygen demand, foul odors, etc., are often carried by vapors to be condensed in industrial processes. Certain of these contaminants are more volatile than the primary constituent of the vapor to be condensed.... | 08/05/1980 |
| 4119485 | Heat exchangers and evaporators Apparatus for effecting heat interchange of fluids, at least one of the fluids containing dispersed or dissolved solids, said apparatus having one or more fluids contacted surfaces which are (1) preferentially oil wettable and (2) substantially zero water... | 10/10/1978 |
