Abstract
A chemical recycling process and facility for turning one or more waste plastics into syngas are provided. Generally, the chemical recycling process involves: (a) liquefying at least one solid waste plastic to form a liquefied waste plastic; (b) introducing at least a portion of the liquefied waste plastic into a partial oxidation (POX) gasifier; and (c) converting at least a portion of the liquefied waste plastic in the POX gasifier into a syngas composition.
Claims21
A chemical recycling process comprising:
- (a) liquefying at least one solid waste plastic to form a liquefied waste plastic;
- (b) introducing at least a portion of said liquefied waste plastic into a partial oxidation (POX) gasifier;
- and
- (c) converting at least a portion of said liquefied waste plastic in said POX gasifier into a syngas composition.
A chemical recycling process comprising:
- (a) liquefying at least one solid waste plastic in a melt tank to form a molten waste plastic;
- (b) removing one or more halogens from said molten waste plastic to form a halogen-depleted molten waste plastic;
- (c) introducing at least a portion of said halogen-depleted molten waste plastic into a partial oxidation (POX) gasifier;
- and
- (d) converting at least a portion of said halogen-depleted molten waste plastic in said POX gasifier into a syngas composition.
A chemical recycling facility comprising:
- (a) a waste plastic liquification system for liquefying at least one solid waste plastic and forming a liquefied waste plastic;
- and
- (b) a partial oxidation (POX) gasifier connected in fluid communication with said plastic liquification system and configured to receive at least a portion of said liquefied waste plastic and convert at least a portion of said liquefied waste plastic to a syngas composition.
