Patent number: 4708878Abstract: A method for the temperature control of a liquid and an apparatus to effect such a method wherein the heating of the liquid is carried out by irradiation with acoustic ultrasonic waves. Temperature measurement is effected by a probe immersed in the liquid or by contact-free measurement of infra-red radiation from the liquid. Temperature control is effected by comparison of the measured temperature with a predetermined desired temperature. Since the acoustic ultrasonic heating is thermally inertialess, extreme accuracy of temperature control is possible.Type: GrantFiled: June 17, 1985Date of Patent: November 24, 1987Inventors: Ulrich Hagelauer, Uwe Faust

Patent number: 4511437Abstract: A process for continuous rectification of a liquid mixture containing alcohols, particularly a liquid fermate, employs a plurality of distillation columns to which the liquid mixture is fed in parallel, and which have successively reduced operating pressures and temperatures from an initial one to a final one thereof. The top vapor distillate from the higher-pressure columns supplies driving heat to the sumps of the next successively lower-pressure columns. Direct steam at 130.degree. C. to 160.degree. C. is fed to the sump of the column operated at the highest pressure. Direct steam is generated by indirect heat exchange of water with the top vapor withdrawn from the columns, and the resulting direct steam is fed to the sumps of the next-lower-pressure columns. The apparatus can also include a section for the production of absolute alcohol.Type: GrantFiled: November 4, 1982Date of Patent: April 16, 1985Assignee: Hoechst AktiengesellschaftInventors: Gunter Heck, Aladar Lienerth, Egon Malow, Karl-Heinz Schwarz, Uwe Faust
