Embodiments may include methods and systems for purifying a product and recovering a solvent. In a first stage, a raw feed comprising an initial solvent fraction and an initial product fraction may be heated using a first heat exchanger, and an intermediate vapor fraction of the initial solvent fraction may be vaporized using a first vapor liquid separator to yield an intermediate product comprising intermediate solvent and intermediate product fractions. The intermediate vapor fraction may be condensed to a first solvent condensate using a first condenser. In a second stage, the intermediate product may be heated using a second heat exchanger, and a final vapor fraction of the intermediate solvent fraction may be vaporized using a second vapor liquid separator to yield a purified product comprising final solvent and final product fractions. The final vapor fraction may be condensed to a second solvent condensate using a second condenser.
