Assignee:

GTC Technology US, LLC - Houston TX

International Classification:

C07C 7/10

US Classification:

585833, 585834, 585864, 585867

Abstract:

Apparatuses and systems for removing heavy hydrocarbons from a solvent stream are disclosed herein. The apparatuses extract heavy hydrocarbons into light hydrocarbons and provide a solvent stream having the heavy hydrocarbons removed. Two water washing steps are used to remove residual solvent from the heavy hydrocarbon solution in light hydrocarbons. In some embodiments, the second water wash is used for processing subsequent batches of the solvent stream. The heavy hydrocarbons and solvent can be recovered and processed further. Methods for removing heavy hydrocarbons from a solvent stream are also disclosed herein.

Abstract:

Various embodiments of the invention herein described generally relate to novel processes for the production of aromatic acids by fixed bed catalytic oxidation of aromatic compounds carrying at least one oxidizable substituent group attached directly to the carbon atom of the corresponding aromatic nucleus. In an embodiment, a novel oxidation process of the present invention comprises the steps of: a) catalytically oxidizing, with an oxidation catalyst, a liquid phase aromatic acid precursor in the presence of a gaseous oxygen source; b) separating a finished product; c) purging the solvent and the oxidation catalyst; d) optionally recycling at least a portion of the solvent into the oxidation reactor; e) recovering at least a portion of the oxidation catalyst; f) recharging the at least a portion of the oxidation catalyst over a solid recharging catalyst bed; and (g) feeding a reactivated oxidation catalyst to the oxidation reactor.
