Abstract

The invention relates to a process and to an apparatus for carrying out the process for degassing of liquids at reduced pressure using a centrifugal force to produce a thin layer of liquid using a conical rotary body the interior of which is maintained at a reduced pressure and in which the liquid is conducted through a hollow shaft and is sprayed by means of a distributor to the conically widening internal surface of the rotary body into a thin film of liquid to be degassed and to flow to an annular collecting chamber from which the degassed liquid is conducted to the center of the centrifuge chamber and discharged from the rotary body against the reduced pressure through the hollow fixed shaft by means of a removal disc.
