    摘要： The present invention provides fractional condensation apparatuses, systems and methods that can recover volatile products from highly diluted liquid and vapor feed mixtures with high purity and recovery yield, both in batch and continuous distillation, while being also designed to achieve low-cost and efficient recovery processes. Single apparatuses and columns can be connected to each other to expand or shrink the column length for desired separation. The apparatuses, systems and methods can be applied to separate mixtures with both narrow and wide boiling point ranges.

    摘要： A method of separating a polymer from a biomass containing the polymer, includes contacting the biomass with a solvent system, the solvent system including a solvent for the polymer and a precipitant for the polymer, to provide a residual biomass and a solution that includes the polymer, the solvent for the polymer and the precipitant for the polymer; and applying a centrifugal force to the solution and residual biomass to separate at least some of the solution from the residual biomass; where, the polymer is a polyhydroxyalkanoate; the precipitant comprises at least one alkane; the solvent for the polymer is selected from the group consisting of ketones, esters and alcohols and combinations thereof; and the biomass comprises a slurry of the biomass and water.
