Publication number: 20230089058Abstract: Processes and facilities for producing recycled chemical products from waste plastic are described herein. The processes include treating process streams, such as a pyrolysis gas stream and/or at least a portion of a cracker furnace effluent stream, in a caustic scrubber process to remove certain components, such as carbon dioxide. The spent caustic solution from the caustic scrubber process is then recycled and reused in other caustic processes within the facility, which can include a halogen neutralization process from removing halogens from a liquification process off-gas.Type: ApplicationFiled: September 16, 2022Publication date: March 23, 2023Applicant: Eastman Chemical CompanyInventors: Michael Gary Polasek, Daryl Bitting, Xianchun Wu, David Eugene Slivensky
