Definitions

  • the invention relates to a method for converting cracking furnaces for the thermal cracking of hydrocarbons with a radiation and a convection zone, the cracking furnaces being fastened by scaffolding.
  • the present invention is therefore based on the object of demonstrating a method of the type mentioned at the outset by which the performance of existing cracking furnaces can be introduced to the modern cracking furnaces in a cost-effective and simple manner.
  • This object is achieved in that at least two existing cracking furnaces are combined to form a structural unit, the convection zones of the existing cracking furnaces being reduced and the radiation zones being expanded to the height of the existing scaffolding of the original cracking furnace, the existing scaffolding of the original cracking furnace in and / or above the intermediate area of the original cracking furnaces are expanded by an additional scaffold connecting the cracking furnaces and the convection zones of the cracking furnaces are built into this additionally constructed framework.
  • the method according to the invention expands the performance of the cracking furnaces by utilizing the existing scaffold construction and the predominant part of the radiation zone of the cracking furnaces.
  • the conversion of the convection zone of the cracking furnaces leads to a higher overall efficiency of the cracking furnaces and to an increase in steam generation.
  • the adaptability of the cracking furnaces to different types of input materials to be split increases.
  • quench coolers for cooling the cracked gases are installed in the cracked tubes (outlet tubes) leading out of the radiation zone of the cracking furnaces.
  • These heat exchangers are also referred to as linear heat exchangers. Their installation leads to a substantial increase in steam generation.
  • the installation of the quench cooler extends the furnace runtime.
  • Figure 1 shows an example of two identical cracking furnaces with the radiation zones 1a and 1b and the convection zones 2a and 2b.
  • the radiation (1a, 1b) and convection (2a, 2b) zones are built into the scaffolding 3a and 3b.
  • the can 4a and 4b lead the feed to be split and are not shown in Figure 1, but only indicated.
  • the cracking tubes are usually installed in such a way that the feed material in the cracking tubes is guided through the radiation zone of the cracking furnace, the straight tube sections running horizontally and tube elbows being attached in the areas near the side walls.
