Claim 17:
18. A system for processing polyester-cotton blend textile waste comprising:
a rotating hydrolysis reactor comprising:
a reactor housing defining an interior chamber for receiving a water and chemical slurry associated with the hydrolysis reaction;
an inner drum supported in the interior chamber for rotation relative to the reactor housing and for receiving polyester-cotton blend textile waste, the inner drum including a sidewall that is perforated with a plurality of holes;
a plurality of spaced apart ribs supported on an interior surface of the sidewall of the inner drum for agitating the polyester-cotton blend textile waste when the inner drum is rotated relative to the reactor housing; and
a hydrolysate recovery system configured to receive liquid hydrolysate from the rotating hydrolysis reactor comprising:
a recovery vessel configured to receive liquid hydrolysate from the rotating hydrolysis reactor, the recovery system including an agitator and a heating system;
an acid supply system for directing acid to the recovery vessel;
a TPA recovery filter configured to capture TPA precipitate as liquid hydrolysate from the recovery vessel is directed through the TPA recovery filter; and
a glycol recovery condenser in communication with the recovery vessel for receiving and condensing into liquid ethylene glycol vapors from the recovery vessel.
