Definitions

  • the description relates to a process for obtaining a polymerizable fraction of valuable materials, consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindens and fractions, the boiling points of which are between styrene and methylindens, from the cracking gases of a steam cracker plant.
  • the above valuable fraction is a starting product for various adhesive resins.
  • Japanese Patent 87-190136 shows a process in which a polymerizable fraction on C 9 -C 10 cuts is obtained from residual oil by distillation.
  • US Pat. No. 4,371,428 describes a process for separating vinyltoluene from other alkenyl aromatics by means of an extraction distillation.
  • indene a method is described in US Pat. No. 4,827,078 which shows the extraction from a petrochemical mixture by means of adsorption with zeolites.
  • the task therefore was to extract the valuable material fraction by means of a simple, economical process step.
  • This object is achieved in that a side stream of the cracked gas column is divided by means of a distillation unit into the valuable fraction and into fractions which are returned to the cracked gas column.
  • a product stream is drawn off from the cracking gas column of the steam cracker plant on a suitable tray and contains, for example, the desired component - valuable material fraction in an enrichment of approx.
  • the products boiling higher than the product of value, such as naphthalene and undesired C 10 and higher components, are drawn off in the column at the bottom and are advantageously returned to the cracking gas column below the removal tray.
  • the valuable fraction is advantageously removed from the gas phase of the column and condensed.
  • the process according to the invention is characterized by a high yield of the valuable material fraction. Another advantage is that a lower energy consumption is necessary if the enriched side stream of the cracking gas column is worked up for the valuable fraction than to obtain the valuable fraction by distillation of pyrolysis gasoline. In the event of faults in the column for obtaining the valuable material fraction, the pyrolysis gasoline processing of the steam cracker is not affected and the availability of the steam cracker is not impeded.
  • the valuable fraction does not contain any dicyclopentadiene, which changes the properties of the valuable fraction, and, on the other hand, when cyclopentadiene / dicyclopentadiene is obtained from pyrolysis gasoline from the steam cracker, which components which impair the purity of the dicyclopentadiene, such as indene, already separate vinyl toluene are.
  • the valuable material fraction obtained according to the process according to the invention contains, for example, 4% by weight of styrene, 20% by weight of methylstyrene and vinyltoluenes, 20% by weight of indene and 11% by weight of methyl indene.
  • the products 3 boiling lower than the valuable material fraction are drawn off overhead and returned to the cracked gas column.
  • the products 4 boiling higher than the valuable material fraction are drawn off and fed back to the cracking gas column.
  • the column is equipped with approx. 14-18 practical exchange trays, such as dual-flow trays, sieve or valve trays.
  • the operating data of the column are: Print: ⁇ 1.9 bar on the head Head temperature: ⁇ 125 ° C Temperature at the swamp: ⁇ 193 ° C Temperature at the point of withdrawal of the recyclable material fraction: ⁇ 176 ° C
  • the removal point 5 of the valuable material fraction takes place between the 9th and 13th Exchange tray, calculated from the top of the column.
