Abstract

See full text

Process and apparatus for recovering a product stream from a waste plastic feedstock and reducing the endpoint of the product stream is provided. A polymer oil is produced as a product stream by pyrolyzing the waste plastic feedstock in a pyrolysis reactor to produce a pyrolysis reactor effluent and passing the reactor effluent stream to a contact condensing column. In the contact condensing column, the pyrolysis reactor effluent stream is separated into a vapor product stream and a liquid product stream. The vapor product stream is recovered from the condensing column and the liquid product stream is passed back to the pyrolysis reactor for further reduction.
