  • Solvent exchange column and a method of use therefor
    Patent number: 6471865
    Abstract: The present invention provides a solvent exchange column for continuously exchanging styrene monomer with the solvent used to produce polybutadiene and a method of use therefor. The solvent exchange column includes an exchange plate support structure coupled to and supporting spaced apart exchange plates, wherein each of the exchange plates has holes located therein to allow a passage of fluid therethrough. The solvent exchange column further includes a vapor ventilation system for allowing the volatized solvent to exit the solvent exchange column.
