Does JB use every element of the system as claimed in claim 1, 8 or 9? I don't know. However, the patent claims a systemm having at least every one of those listed elementss, not just any subset of them.
1. A system for recycling plastic material, comprising:
a treatment chamber containing a material comprising
plastic to be recycled; a heating system that heats said treatment chamber to a
temperature that results in pyrolytic cracking of said
plastic;
a vacuum system that pulls a vacuum on said treatment chamber and removes vapor from said treatment chamber, wherein said vapor comprises pyrolyzed inorganic species and gaseous organic species resulting from said pyrolytic cracking of said plastic;
a control system including computer operable instructions that control said heating system to heat said chamber in incremental steps through a series of graduated temperature set points;
a vapor treatment vessel connected to said treatment chamber, said vapor treatment vessel including a vapor exit port, wherein said vapor treatment vessel comprises a reflux heat exchanger; and
a fume scrubber connected to said vapor treatment vessel, wherein said fume scrubber comprises a pH adjusted or buffered aqueous media, and said vapor generated as a result of said pyrolytic cracking of said plastic is directly contacted by the aqueous media within said fume scrubber, resulting in condensation of gaseous organic species contained within said vapor.
A system for recycling plastic material, comprising:
a treatment chamber containing a material comprising
plastic to be recycled; a heating system that heats said treatment chamber to a 20
temperature that results in pyrolytic cracking of said
plastic;
a vacuum system that pulls a vacuum on said treatment chamber and removes vapor from said treatment chamber, wherein said vapor comprises pyrolyzed inorganic 25 species and gaseous organic species resulting from said pyrolytic cracking of said plastic;
a control system including computer operable instructions that control said heating system to heat said chamber in incremental steps through a series of graduated tempera- 30 ture set points; and
a vapor treatment system connected to said treatment chamber, said vapor treatment system configured to condense hydrocarbons contained within said vapor generated as a result of said pyrolytic cracking of said plastic 35 and comprising a fume scrubber wherein said fume scrubber comprises a pH adjusted or buffered aqueous media, and said vapor generated as a result of said pyrolytic cracking of said plastic is directly contacted by the aqueous media within said fume scrubber, resulting in 40 condensation of gaseous organic species contained within said vapor.
9. A system for recycling plastic material, comprising:
a treatment chamber containing a material comprising plastic to be recycled; 45
a heating system that heats said treatment chamber to a temperature that results in pyrolytic cracking of said plastic;
a vacuum system that pulls a vacuum on said treatment chamber and removes vapor from said treatment chamber, wherein said vapor comprises pyrolyzed inorganic species and gaseous organic species resulting from said pyrolytic cracking of said plastic;
a control system including computer operable instructions that control said heating system; and
a vapor treatment system connected to said treatment chamber, said vapor treatment system comprising a fume scrubber comprising a pH adjusted or buffered aqueous media, wherein said fume scrubber is configured such that, said vapor resulting from said pyrolytic cracking of said plastic is directly contacted by the aqueous media within said fume scrubber, resulting in condensation of gaseous organic species contained within said vapor.
