Abstract: Recovering a polar hydrocarbon (HC) selective solvent substantially free of hydrocarbons (HCs) and other impurities from a lean solvent stream containing the selective solvent, measurable amounts of heavy aromatic HCs, and polymeric materials that are generated in an extractive distillation (ED) or liquid-liquid extraction (LLE) process. At least a portion of the lean solvent stream is contact in a solvent clean-up zone with a slip stream from the HC feed stream of the ED or LLE process or an external stream. The HC feed stream, such as pyrolysis gasoline or reformate, contains significant amounts of benzene and at least 50% polar (aromatic) HCs and serves as a displacement agent to remove the heavy HCs and polymeric material from the lean solvent stream. A magnetic filter can be used to remove the paramagnetic contaminants from the lean solvent.

The acid is recovered by distillation. In a second embodiment, additional alcohol and/or water are co-fed with the feed or fed directly to a catalytic distillation column, resulting in a liquid bottom product stream of substantially pure acetic acid and a top distillate stream of substantially pure ether.

By calculating the difference between the temperature at the next time and the predicted temperature at the next time, the filter parameter of the adaptive filter is adjusted. This mechanism helps improving the accuracy in temperature predictions.
