Abstract (en)
[origin: CA2151602A1] The invention concerns a method of obtaining, from the cracked gases emerging from a steam cracker, a polymerizable fraction of recyclable material consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindenes and fractions whose boiling points lie between those of styrene and the methylindenes, a secondary stream from the cracked-gas column being divided, by means of a distillation unit, into the fraction of recyclable material and into fractions which are fed back to the cracked gas column.
