Publication number: 20230323023Abstract: Copolyesters made from the direct esterification of terephthalic acid with diols including ethylene glycol, but which contain low diethylene glycol (DEG) content, and processes for making the copolyesters. The copolyesters are characterized by comprising 1.0 wt % or less of DEG without requiring the use of DEG-suppressing additives. The processes are characterized by features including operating at lower pressures and lower EG:TPA feed mole ratios in the first reaction zone, while simultaneously at higher temperatures than typical operation in order to lower incorporation of DEG into the final polymer.Type: ApplicationFiled: June 6, 2023Publication date: October 12, 2023Applicant: Eastman Chemical CompanyInventors: Anne-Martine Sherbeck Jackson, Rachel Elizabeth McLendon, Bruce Roger DeBruin, Michael Paul Ekart, Dale Milton Blakely, Robert Todd Harris

Publication number: 20230227622Abstract: Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise colored plastic-containing mixtures derived as products or co-products from plastic reclaimer facilities and/or municipal recycling facilities. Such mixtures are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable colored plastic-containing mixtures.Type: ApplicationFiled: April 13, 2021Publication date: July 20, 2023Applicant: Eastman Chemical CompanyInventors: Bruce Roger DeBruin, Michael Paul Ekart, Anne-Martine Sherbeck Jackson, Nathan Mitchell West, Zhufang Liu

Publication number: 20230203268Abstract: Chemical recycling facilities for processing mixed waste plastic are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy recovery facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.Type: ApplicationFiled: April 13, 2021Publication date: June 29, 2023Applicant: Eastman Chemical CompanyInventors: Bruce Roger DeBruin, Michael Paul Ekart, Xianchun Wu, David Eugene Slivensky, Daryl Bitting, Anne-Martine Sherbeck Jackson, Nathan Mitchell West, Zhufang Liu
