Definitions

  • the above valuable fraction is a starting product for various adhesive resins.
  • Japanese Patent 87-190136 shows a process in which a polymerizable fraction of Cg-Cio cuts is obtained from residual oil by distillation.
  • US Pat. No. 4,371,428 describes a process for the separation of vinyltoluene from other alkenyl aromatics by means of an extraction distillation.
  • US Pat. No. 4,827,078 shows the extraction from a petrochemical mixture by means of adsorption with zeolites.
  • This object is achieved according to the invention in that a secondary stream of the cracked gas column is divided into the valuable fraction and into fractions which are returned to the cracked gas column by means of a distillation unit.
  • the products boiling higher than the product of value such as, for example, naphthalene and undesired cio- and higher components, are taken 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 material fraction than to obtain the valuable material fraction by distillation of pyrolysis gasoline.
  • 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
  • the components which impair the purity of the dicyclopentadiene such as indene, vinyl toluene, have already been separated off.
  • the recyclable fraction obtained by 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 methylenene.
  • the products 3 boiling lower than the valuable fraction are withdrawn overhead and returned to the cracked gas column.
  • the products 4 boiling higher than the valuable material fraction are taken off at the bottom and fed back to the cracking gas column.
  • the column is equipped with approximately 14-18 practical exchange trays, such as dual-flow trays, sieve trays or valve trays.
  • the operating data of the column are:
  • 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.
