Equipment for preparing polyolefin elastomer

Equipment for preparing a polyolefin elastomer, the equipment comprising:

• 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 an unreacted material and the water are evaporated and a polymer product remains;
• and
• a water removal process in which the water from the unreacted material and the water removed from the finisher is removed, and the remainder (finisher reaction treatment flow) is discharged;
• and a primary distillation column which distills secondarily devolatilization circulation flow removed from the secondary devolatilizer and the finisher reaction treatment flow discharged from the water removal process so as to recover flow separated from a middle portion thereof to the reactor.
