Abstract: A process and a device are described for separating a solid residue, after separation, from a solution of the residue in evaporable materials and/or solvents with the addition of up to 20% by weight of high-boiling hydrocarbons that are inert under evaporation conditions of the evaporable materials, heating the mixture to evaporation temperature under vacuum, whereby the evaporable materials evaporate, are drawn off and condensed, and the residue is obtained as a free-flowing solid, the residue solution being introduced onto a stirred bed of granular solid material kept at the evaporation temperature.

Abstract: A candle type precoated filter for residual volume filtration has a pressure vessel having a cylindrical upper part and a conical base, a plurality of filter elements arranged substantially vertically and including at least one residual filter element and other filter elements formed so that the at least one residual filter element is lengthened toward the base and is longer than the other filter elements and a separating wall which separates the residual filter element in an upper portion of the pressure vessel from the other filter elements so as to be tight against media and to project out in a lower portion of the pressure vessel beyond a length of the other filter element.

Abstract: The invention relates to a multiple phase flow tube for evaporating and reacting components in compound mixtures in which a spiral pipe is arranged within a multiple phase flow pipe. The components are propelled by means of an internally flowing gas stream in an annular shaped passage formed by a spiral tube and a second tube arranged as a core of the spiral tube. The second tube contains a heat exchange medium. The spiral tube is arranged within a cylindrical casing which contains a heat exchange medium. A gaseous stream of a reduced amount is then sufficient for carrying out the particular chemical process desired.
