A continuous vacuum fractionation system for separation of one or more of the plurality of components present in a raw cannabis extract into at least an overhead fraction, a bottoms fraction, and a side stream fraction, wherein the raw cannabis extract may be prepared by any of a variety of extraction techniques. The system includes an extract supply assembly having a primary feed pump, and one or more continuous fractionation units each including a modular fractionation column. Each column has a re-boiler, a close-coupled overhead condenser, and at least one modular fractionation stage, and further, the columns are operable in either series or parallel configurations. The close-coupled overhead condenser has an oversized impingement plate overlying a condenser inlet to minimize non-vapor components from entering and contacting the condenser. A vacuum assembly is provided to maintain at least the modular fractionation columns under a predetermined vacuum during operation.

The present invention is directed to a system and process for fractionating a hydrocarbon liquid feed using a single dividing wall column (DWC), an externally heated reboiler connected to the DWC, and a deisobutanizer (DIB) integrated with a compressor. The majority of all externally supplied heat energy supplied to the system is input to the system via the externally heated reboiler of the DWC.

The invention relates to a process (100) for deriving polymerizable aromatic compounds having nine carbon atoms (S) in which a component mixture (B) is formed at least partially by steam cracking, in which the component mixture (B) is subjected to a workup (2, 3, 4, 5) comprising a gasoline removal (5) and thereafter is a compression (8) and a fractionation (10), and wherein one or more pyrolysis gasoline fractions (H, L) is or are formed in the gasoline removal (5) and/or the compression (8). The invention provides that a separation feed is formed which comprises predominantly exclusively pyrolysis gasoline from the or at least one of the pyrolysis gasoline fractions (H, L) and that the separation feed is subjected to a separation (7), wherein in the separation (7) at least one fraction (P) enriched in aromatic compounds having nine carbon atoms compared to the separation feed is formed. A corresponding plant likewise forms part of the subject matter of the invention.
