Zusammenfassung: | The present invention relates to equipment for preparing a polyolefin elastomer, and the equipment for preparing a polyolefin elastomer according to the present invention may include a reactor to which a solvent and a raw material are supplied, a primary devolatilizer which devolatilizes a product discharged from the reactor to remove an unreacted material (primary devolatilization recovery flow), and to discharge the remainder thereof (primary devolatilization preparation flow), a secondary devolatilizer which re-devolatilizes the primary devolatilization preparation flow discharged from the primary devolatilizer to further remove an unreacted material (secondary devolatilization recovery flow), and to discharge the remainder thereof (secondary devolatilization preparation flow), a finisher which scrubs, using water, the secondary devolatilization preparation flow discharged from the secondary devolatilizer, so that the unreacted material and the water are evaporated and a polymer product remains, and a flash drum which removes low-molecular materials (impurity removal flow) from the primary devolatilization recovery flow removed from the primary devolatilizer, and recovers the remainder to the reactor. |
