Publication number: 20240294729Abstract: A process and a system for depolymerizing plastic, such as waste polyester, into marketable monomers. A heterogeneous mixture of plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate just high enough to maintain a particle speed great enough to keep the plastic particles in suspension. The temperature of the heterogeneous mixture is raised in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied plastic monomer. The homogeneous solution is cooled to solidify and precipitate the monomer. The precipitated monomer is separated from the solvent to be recycled. The solvent is recirculated to be reused as a constituent of the heterogeneous mixture.Type: ApplicationFiled: May 13, 2024Publication date: September 5, 2024Applicant: Premirr Plastics Inc.Inventors: Matthew Craig Parrott, James Christopher Luft, Donald B.

Publication number: 20230265257Abstract: A continuous flow process and system for depolymerizing plastic. A heterogeneous mixture of solid plastic particles, a solvent, and a catalyst are pumped continuously through a heating zone at a flow rate resulting in a particle speed sufficient to keep the plastic particles in suspension. The heterogeneous mixture is heated in the heating zone and maintained in a hold zone to complete depolymerization of the mixture into a homogeneous solution containing a liquefied reaction product. The homogeneous solution is cooled to solidify and precipitate a solid reaction product. The solid reaction product is separated from the solvent to be recycled. Contaminants are removed from the solvent, and the solvent is recirculated for use as a constituent of the heterogeneous mixture.Type: ApplicationFiled: April 28, 2023Publication date: August 24, 2023Applicant: Premirr Plastics Inc.Inventors: Matthew Craig Parrott, James Christopher Luft, Donald B.

Patent number: 11396588Abstract: A process and a system for continuously depolymerizing plastic is disclosed. The system may comprise a mixer for producing a heterogeneous reaction mixture comprising plastic particles and a solvent, a pump for transmitting the reaction mixture at a particle speed sufficient to maintain the plastic particles in suspension in the solvent, a heating apparatus for heating the reaction mixture to its reaction temperature, a hold tube for maintaining the reaction mixture at or above the reaction temperature to facilitate conversion into a homogeneous reaction solution, and a settling tank to allow a solid reaction product to precipitate from the homogeneous reaction solution once cooled.Type: GrantFiled: September 20, 2019Date of Patent: July 26, 2022Assignee: Premirr Plastics Inc.Inventors: Matthew Craig Parrott, James Christopher Luft, Donald B.
