    Abstract: A process is proposed for preparing chlorine by oxidizing hydrogen chloride in the presence of a heterogeneous particulate catalyst by the Deacon process in a fluidized bed reactor (1), wherein the heat of reaction is removed by evaporative cooling with water which circulates in the tubes (2) of a shell and tube heat exchanger, wherein the water is supplied from a steam drum (4) via a feed line (5) to the tubes (2) of the shell and tube heat exchanger at one end thereof, it heats up in the tubes (2) by absorbing the heat of reaction and evaporates partly to obtain a water/steam mixture which is passed back into the steam drum (4) via a return line (6) at the other end of the tubes (2) of the shell and tube heat exchanger, which is characterized in that the maximum pressure for which the fluidized bed reactor (1) has to be designed for the event of fracture of a tube (2) of the shell and tube heat exchanger is minimized by introducing a valve (7) into the feed line (5) and into the return line (6), said valve (7), in the event of a pressure rise owing to the fracture of a tube (2), blocking the feed line (5) and the return line (6), thus preventing water from flowing out of the steam drum (4) into the fluidized bed reactor (1).

    Abstract: The invention relates to a method for continuously cleaning a solid mixture, comprising a valuable product that can be sublimated, and components that can be sublimated more easily and with more difficulty, by fractionated sublimation/desublimation in a hot wall tube furnace (1), by supplying the solid mixture together with an inert gas flow, in which the solid mixture is dispersed by way of a dispersing organ (2), at an end of the hot wall tube furnace (1); - heating the dispersed solid mixture in the hot wall tube furnace (1) at a temperature at which the valuable product sublimates, to obtain a gas mixture comprising components that are more difficult to sublimate than the valuable product as solid particles; - passing the gas mixture, comprising components that are more difficult to sublimate than the valuable product as solid particles, over a hot gas filter (3) having a suitable pore size in order to retain the solid particles that sublimate with more difficulty than the valuable product; - cooling the gas mixture, from which the components that are more difficult to sublimate than the valuable product are separated, to a temperature at which the valuable product desublimates and at which the components sublimating more easily than the valuable product do not yet desublimate to obtain a gas mixture comprising the particle-shaped valuable product; and - separating the cleaned, particle-shaped valuable product from the cooled gas mixture.
