Definitions

  • the technical gases are usually natural gas or synthesis gas, wherein the synthesis gas is obtained from fossil fuels such as petroleum or coal and from biological raw materials.
  • Natural gas and synthesis gas contain in addition to the useful valuable gases and interfering components such as sulfur compounds, in particular sulfur dioxide, carbon dioxide and other components to be separated, as well as hydrogen cyanide and water vapor.
  • flue gases from combustion of fossil fuels belong to the group of technical gases, from which also disturbing components, such as e.g. Carbon dioxide are removed.
  • the components to be separated can also be useful gases which are to be separated for a specific purpose.
  • Both physical and chemical absorbents can be used for absorption.
  • Chemically acting absorbents are z.
  • As aqueous amine solutions, alkali salt solutions, etc. Selexol, propylene carbonate, N-methyl-pyrrolidone, Mophysorb, methanol, etc. belong to the physical absorbents.
  • the components to be separated are absorbed by the liquid absorbent. While the solvent-insoluble gas leaves the absorption device at the head, the components to be separated remain dissolved in the liquid absorbent and leave the absorption device at the bottom.
  • the loaded solution is usually preheated by heat exchange with the hot, regenerated solution, recovering some of the energy needed for desorption in the desorption apparatus.
  • a reboiler located at the bottom of the desorption is generated by means of a heating medium vapor by partial evaporation of the solvent at the bottom within the desorption.
  • the steam thus produced acts as a stripping medium in order to expel the component to be separated from the loaded solution.
  • the loaded solution is removed with stripping medium from the recorded components to be separated.
  • the expelled components to be separated leave the desorption apparatus overhead, wherein the vapor portion of the stripping medium is condensed in a top condenser and fed back to the desorption apparatus.
  • the regenerated solution freed from the components to be separated leaves the desorption device at the sump, wo in the solution after the heat exchange is usually cooled returned to the head of the absorption device. This completes the cycle of absorption and desorption processes.
  • an absorption temperature of 20 ° C up to 70 ° C proved to be favorable to remove the components to be separated from the technical gas.
  • the laden with components to be separated solution can be regenerated by relaxing to a lower pressure and / or stripping, the components to be separated are released again and / or stripped off by steam. After the regeneration process, the absorbent can be cooled and reused accordingly.
  • the temperature required for desorption in a desorption device is higher than the temperature for absorption by the absorbent in an absorption device.
  • the desorption is operated in most cases at a temperature between 80 ° C to 140 ° C, and an absolute pressure of 0.2 to 3 bar.
  • absorption and desorption heat recovery can be achieved by the heat exchange between réelleadelnder and cooling absorbent solution by means of a heat exchanger.
  • the medium to be heated is desirably preheated
  • the medium to be cooled is likewise cooled down in a desirable manner, as a result of which the regeneration energy requirement to be supplied from outside is significantly reduced.
  • EP 1 606 041 B1 discloses a method for the selective removal of acid gas components from natural gas or synthesis gas, wherein the sour gas component is selectively removed within two absorption stages, in which the loaded solution is depressurized in two stages in a flash vessel to a selected pressure and subsequently is introduced into the desorption for desorption.
  • WO 2010/086039 A1 teaches a method and apparatus for separating carbon dioxide from an exhaust gas of a fossil-fired power plant.
  • the driving modes "split-feed” and “Lean Solvent Flash” combined, only the combination of both steps leads to a more favorable overall system efficiency of the power plant process.
  • the implementation of the method according to WO 2010/086039 A1 requires compared to the prior art, a significantly higher equipment complexity, since in this case both a vacuum compression stage, as well as a further compression stage would be needed.
  • EP 1 736 231 A1 discloses a method and a device for removing carbon dioxide, in which case different variants have been presented in order to improve energy efficiency. Due to the thermal shading presented there, however, only a part of the energy which is supplied to the regeneration device can be recovered, since most of the energy still present in the vapors originating from the flash container described is not returned to the regeneration device but is removed by means of an external cooler and thus lost to the system. In order to be able to transfer the heat sufficiently from and to the enriched solution of the flash tank, a significantly higher level of additional equipment is required, due to additional heat exchangers, coolers, etc. For example, a required intermediate task in the absorber increases the required total height of the absorber and thus also the costs.
  • the invention is therefore based on the problem to provide an economically improved process for the removal of component to be separated from industrial gases by means of absorption and desorption with heat recovery available, in particular to further reduce the energy consumption required externally.

  • the components to be separated by the stripping medium leave the head of the stripping section (22b) as vapors, which are further introduced into the heat transfer section (22a), cooled accordingly, and leave the desorption device (22) over the head.
  • the freed after desorption of the components to be separated solution leaves the desorption device (22) at the bottom, exchanges the heat in the heat exchanger (21) with the enriched solution, is then cooled and is returned to the absorption device (20).

  • Heat is transferred from the regenerated solution to the enriched solution in the heat exchanger (21).
  • the temperature difference between the hot, regenerated solution and the warmed, laden solution, as well as between the cooled, regenerated solution and the cold, warm-up, loaded solution should normally be not less than 10K.
