| titleOfInvention | Processes and equipment for the separation of 1,2,4 trimethylbenzene (Pseudocumene) from a mixture containing aromatic hydrocarbons |
| abstract | A method for separating and recovering the compound called Pseudocumene from a crude mixture (31, 51) containing aromatic hydrocarbons with at least nine carbon atoms that is constituted by the steps of: - predisposing a vertical elongated container having a wall of interior separation (83, 85, 89, 93 ', 285, 385) said container and said interior separation wall (83, 85, 89, 93', 285, 385) defining a first longitudinal chamber (73, 75, 79- 79 ', 273, 96, 375) and a second longitudinal chamber (73', 75 ', 79' ', 273', 96 ', 376) within said elongated container; - arrangement of a differential expansion compensation means between said elongated container and said interior separation wall (83, 85, 89, 93 ', 285, 385) to compensate for the differential expansion caused by temperature differences between said first chamber (273 ) and said second chamber (273 '), wherein said inner separation wall (285) is internally fixed to an enclosure (217) of said elongated vertical container (200) at an extension of the short peripheral part of said wall of separation (285), while other peripheral parts of said separation wall (285) have a relative freedom of movement with respect to said enclosure (217), in order to allow the expansion of said separation wall (285) with with respect to said housing envelope (217); - feeding said raw mixture (31, 51) into said first longitudinal chamber (73, 75, 79-79 ', 273, 96, 375) and maintaining said first longitudinal chamber (73, 75, 79-79', 273 , 96, 375) within a first predetermined working temperature range and at a first predetermined working pressure as well; - extracting a first vapor fraction from the upper part (32, 42, 52) from said first longitudinal chamber (73, 75, 79-79 ', 273, 96, 375) said first vapor fraction comprising the part upper (32, 42, 52) aromatic hydrocarbons that are lighter than said Pseudocumene; - the extraction from said first longitudinal chamber (73, 75, 79-79 ', 273, 96, 375) of a first lower fraction (38, 98) comprising aromatic hydrocarbons that are heavier than said Pseudocumene; wherein said first working temperature range and / or said first working pressure is selected such that the Pseudocumene is present in practically only a fraction selected between said first fraction of the upper part (32, 42, 52) and said first lower fraction (38, 98), so that a fraction containing Pseudocumene and a mixture practically free of Pseudocumene are extracted from said first longitudinal chamber (73, 75, 79-79 ', 273, 96, 375); - the feeding of at least a part (33, 42, 47, 52) of said fraction containing Pseudocumene in said second longitudinal chamber (73 ', 75', 79 '', 273 ', 96', 376) that is maintained within a second predetermined working temperature range and a second predetermined working pressure; - extracting a second fraction of steam from the upper part (32 ', 92') from said second longitudinal chamber (73 ', 75', 79 '', 273 ', 96', 376); - extracting a second lower fraction (38 ', 98', 131 ') from said second longitudinal chamber (73', 75 ', 79' ', 273', 96 ', 376), wherein said second temperature range of work and / or said second working pressure are selected such that the Pseudocumene is present practically pure only in a fraction selected between said second fraction of the upper part (32 ', 92') and said second lower fraction (38, 98 ', 131'), depending on whether said quantity (33, 42, 47, 52) of said fraction containing Pseudocumene (32, 42, 47, 52, 52), which is extracted from said first longitudinal chamber (73 , 75, 79-79 ', 273, 96, 375) and is supplied to said second longitudinal chamber (73', 75 ', 79' ', 273', 96 ', 376), respectively, is at least one part ( 47) of said first lower fraction (38, 98) or at least a part (33, 42, 52) of said first fraction of the upper part (32, 42, 52), wherein, in particular, said crude mixture ( 31, 51) d and aromatic hydrocarbons is obtained by means of a catalytic reform treatment of a distillation fraction of crude oil, in particular, by a catalytic reform of a virgin naphtha, - the compensation of differential expansions of said interior separation wall (83, 85, 89 , 93 ', 285, 3859 due to a temperature difference between said first chamber (73, 75, 79-79', 273, 96, 375) and said second chamber (73 ') by said differential compensation means which are located between said elongated container and said interior partition wall (83, 85, 89, 93 ', 285, 385). |
