摘要： A process is proposed for continuously purifying a solid mixture comprising a sublimable product of value and components with lower and higher sublimation temperatures by fractional sublimation/desublimation in a hot wall tubular oven (1) with supply of the solid mixture together with an inert gas stream, into which the solid mixture is dispersed by means of a dispersing unit (2), at one end of the hot wall tubular oven (1), heating the dispersed solid mixture in the hot wall tubular oven (1) at a temperature at which the product of value sublimes to obtain a gas mixture comprising components with a higher sublimation temperature than the product of value as solid particles, passing the gas mixture comprising components with a higher sublimation temperature than the product of value as solid particles through a hot gas filter (3) with a suitable pore size in order to retain the solid particles with a higher sublimation temperature than the product of value, cooling the gas mixture from which the components with a higher sublimation temperature than the product of value have been removed to a temperature at which the product of value desublimes, and at which the components with a lower sublimation temperature than the product of value are yet to desublime, to obtain a gas mixture comprising the particulate product of value and separating the purified particulate product of value from the cooled gas mixture.

摘要： An apparatus, for separating liquid droplets out of a feed gas stream, includes a delay vessel for preliminary separation of some of the liquid droplets out of the feed gas stream under gravity, with an inlet line for the feed gas stream and an outlet line for the gas stream which has been depleted of liquid droplets and which flows out of the delay vessel and a tangential supply thereof into a centrifugal droplet separator. The outlet line is arranged in the upper region of the delay vessel and spaced apart from the inlet line to such an extent that the delay time of the gas stream in the delay vessel is at a maximum, and with an outlet line for the liquid separated in the delay vessel at the base thereof.
