'A continuous process of Steam distillation solvent extraction for recovery of hydrocarbons arormaticos'.

摘要

Procedure for continuous Steam distillation solvent extraction for recovery of aromatic hydrocarbons.A Current is passed Liquid Rich Aromatic Solvent in a First distillation Zone in Heat Exchange relationship with a stream of water vapor vaporous hydrocarbons and a Second distillation Zone, thereby partially evaporating the vaporous Stream.The Flow of Oil and Water steam is passed into the first Zone to Purify Liquid Stream distillation extracting Aromatic, not the current through a Heat exchanger where Heat Exchange occurs with a stream of poor Solvent The Second area of liquid distillation.It is rich in Aromatic Solvent Flow to the top of the second distillation Zone where comes in contact with steam to remove all of the aromatic hydrocarbons.The current uncertainty which was partially Condensed is passed to a condensation Zone and after the condensation has been in a phase of Product rich in aromatic and a Water Rich phase.
