  • SEPARATION AND RECOVERY APPARATUS
    Publication number: 20240123654
    Abstract: Provided is a separation and recovery apparatus for continuously separating and recovering, from a resin mixture containing a resin containing a hydrolyzable polymer and a resin containing a nonhydrolyzable polymer, a hydrolytic component a of the hydrolyzable polymer A and the nonhydrolyzable polymer B, the apparatus including: a crushing unit that crushes the resin mixture a melting/discharging unit that melts a crushed product obtained by the crushing unit to form a fluid and discharges the fluid at a high pressure; and a hydrothermal reaction treatment unit that continuously subjects the fluid discharged from the melting/discharging unit to a hydrothermal reaction treatment, wherein, in the melting/discharging unit, the hydrolyzable polymer A is hydrolyzed, and the hydrolytic component a thereof is dissolved and transferred into water permeating a sintered alloy diaphragm, thereby separating the nonhydrolyzable polymer B.
