Methods and processes for producing paraxylene from catalytic cracking hydrocarbons, particularly Cand Cstreams, are disclosed. Each of the processing steps may be tailored to the overall objective of high paraxylene yield from a relative inexpensive feedstock.

Processes and systems for obtaining aromatics from catalytic cracking hydrocarbons

The inventive process is directed to the production of xylenes through integration of aromatics methylation and transalkylation. This integrated process maximizes the production of xylenes and eliminates or minimizes the production of benzene.

Apparatuses, systems and methods for separating heavy hydrocarbons from a solvent stream are disclosed. The heavy hydrocarbons and solvent can be recovered and processed further.

Methods and systems for the removal of heavy hydrocarbons

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.

Heavy hydrocarbon removal systems and methods

Methods and apparatuses for extractive distillation using internal addition of steam to an extractive distillation column from a reboiler are described herein. The apparatuses include an extractive distillation column, a reboiler (for example, a kettle reboiler) coupled to the extractive distillation column, and a steam input line. The steam input line is coupled to an internal steam sparger device of the reboiler. Methods utilizing the apparatuses to perform extractive distillation of a hydrocarbon feed stream are also described herein.
