Abstract

The separation of olefine from paraffin <PICT:0650095/IV (b)/1> hydrocarbons is effected by passing the mixture through an adsorption zone in countercurrent flow to a solid adsorbent for one constituent, passing the charged adsorbent through a rectification zone, then stripping the constituent from the adsorbent with a stripping gas and returning a portion of the recovered constituent to the rectification zone. In separating butenes from a C4 fraction containing butenes and butanes, the fraction is introduced through line 1 to adsorption zone 3. Powdered adsorbent is gravitated through zone 3, then through a rectification zone 3a and discharged through line 5 into upflow and stripping pipe 12. Steam, which serves to lift the adsorbent and to strip the butenes therefrom, is introduced into pipe 12 at 15. The solid suspension is discharged into separator 17 and the separated solid is passed to cooler 19 and returned to zone 3 through line 20. The steam-butenes mixture is passed from separator 17 to condenser 40 where steam is condensed, the water-butenes mixture being passed to receiver 45 where the water is withdrawn through line 50, vaporized in 52 and recycled to stripping pipe 12. Butenes are withdrawn through line 53 and a portion recycled to zone 3a through line 55. Unabsorbed gases leave zone 3 through line 28, fines being recovered in precipitator 30. The Specification as open to inspection under Sect. 91 comprises also the application of the process to the separation of aromatics from aliphatics. This subject-matter does not appear in the Specification as accepted.ALSO:A gaseous constituent is recovered from a mixture containing it by passing the mixture through an adsorption zone in counter-current flow to a solid adsorbent for the constituent, passing the charged adsorbent through a rectification zone, then stripping the constituent from the adsorbent with a stripping gas and returning a portion of <PICT:0650095/III/1> the recovered constituent to the rectification zone.

Specified adsorbents are silica gel, activated charcoal and activated alumina. The Specification as open to inspection under Sect. 91 comprises also the application of the process to the separation of aromatics from aliphatics, and of hydrogen sulphide, carbon dioxide, ammonia and nitrogen dioxide from admixture with other gases. This subject-matter does not appear in the Specification as accepted.
