Process for recovery of pyrolysis oil extraction solvent

A process for recovery of pyrolysis oil extraction solvent comprising:

• introducing an extracted phase feed stream comprising pyrolysis oil and an organic solvent to a stripping column through an extracted phase feed stream inlet;
• introducing a stripping vapor feed stream comprising a stripping solvent to the stripping column at a point below the extracted phase feed stream inlet forming a stripping column overhead stream comprising the organic solvent and the stripping solvent and a stripping column bottom stream comprising the pyrolysis oil and the stripping solvent;
• separating the stripping column bottom stream in a flash drum into a vapor stream comprising the stripping solvent and a liquid stream comprising the pyrolysis oil;
• and
• separating the stripping column overhead steam in a recovery column into a recovery column overhead stream comprising the stripping solvent and a recovery column bottom stream comprising the organic solvent.
