    摘要: The invention relates to a method for producing chlorine by the oxidation of hydrogen chloride with oxygen in a fluidized bed reactor in the presence of a particulate catalyst, the reaction heat produced by the exothermic hydrogen chloride oxidation being carried away by water which circulates in the tubes of a shell-and-tube heat exchanger. The method comprises the following steps: (i) heating the fluidized bed reactor to an operating temperature in the range of 350 to 420°C in a heating phase and (ii) reacting the hydrogen chloride with oxygen at the operating temperature in an operating phase. The method is characterized in that (i-1) the fluidized bed reactor is heated to a temperature below the operating temperature in a first heating phase, and (i-2) hydrogen chloride and oxygen are fed to the fluidized bed reactor and reacted in a second heating phase, the fluidized bed reactor being heated to the operating temperature by the reaction heat produced by the exothermic hydrogen chloride oxidation.

    摘要: 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).

    摘要: The invention relates to a method for producing chlorine by gas phase oxidation of hydrogen chloride on a heterogeneous, particulate catalyzer in a fluidized-bed reactor, obtaining a product gas mixture that is freed of any carried catalyzer particles in cyclones (1) disposed in the upper region of the fluidized-bed reactor, comprising a cylindrical upper part (2) having a tangential or spiral inlet (3) for the product gas mixture and narrowing at the lower end thereof via a conical part (4) into a cyclone downpipe (5), and a central immersion pipe (6) in the upper region of the cyclone (1) for diverting the product gas mixture freed of the carried catalyzer particles, characterized in that – one to seven cascades of two to five cyclones each connected in series are used, wherein the cyclones (1) of each cascade, except for the cyclone (1) first permeated, which is designed that approximately 90 to 99% by weight of the carried catalyst particles are precipitated, each comprise a trickle valve (7) at the lower end of the cyclone downpipe (5) comprising an angled pipe terminator (8) and a loose flap valve (9) suspended at an angle α to the vertical, wherein the angle α and the weight of the flap valve (9) are designed so that the torque of the flap valve (9) based on the diameter of the outlet opening out of the angled pipe terminator (8) is in the range of 2 to 300 N/m
