Abstract
In a method of degasification of viscose liquids by means of centrifugation the liquid is brought onto the interior wall of a rotor in the form of a flowing film and divided into a bubble-poor and a bubble-rich portion, the bubble-poor portion being separated from the bubble-rich portion prior to leaving the rotor and withdrawn from the rotor wall by means of at least one pump. In a preferred form of the invention the bubble-rich portion of the liquid is also withdrawn separately from the centrifuge by means of at least one pump and returned for renewed centrifugation. The invention includes a centrifuge for carrying out the method.
