Method for reducing the formation of foam during the treatment of a dispersion or a liquid with water vapour

A process for cooling a continuously inflowing liquid, in particular a dispersion, in vacuo which comprises subjecting the liquid to a flash evaporation in a separator.

Process and apparatus for cooling a continuously inflowing liquid in

A method of filling and emptying storage tanks containing aqueous dispersions, where the storage tank is emptied via a line whose opening is located in the lower section of the storage tank entails filling the storage tank with a line whose outlet follows the changes in the level of the liquid surface in the course of filling and removal procedures, the level of the outlet being adjusted such that the opening is located approximately at the height of the level of the liquid.

Filling and emptying of storage tanks containing aqueous dispersions

A process for compounding polymer dispersions, which comprises circulating the polymer dispersion from a vessel (7) having a stirring device (6) through a line (3) having a mixing device (2) by means of a pump (4) which is located in the line (3), and, before the entry of the circulated polymer dispersion into the mixing device (2), metering at least one solution or dispersion of at least one compounding material from at least one stock container (5) via a supply line (9) into the circulated polymer dispersion.

Compounding of polymer dispersions

Volatile components are eliminated from polyacrylate melts by distilling off the volatile components by a process in which the volatile components are distilled off under reduced pressure, entraining agents are added to the melts at above 100.degree. C. and the melts are simultaneously circulated.
