Abstract: Disclosed are novel curable acrylic modified polyesters comprising the reaction product of 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) and dimethylolpropionic acid modified by an acrylic graft. The curable acrylic modified polyesters have particular utility in waterborne coating compositions. Such waterborne coating compositions provide a good balance of desirable coating properties for metal packaging applications.

Abstract: Processes for recovering dialkyl terephthalates. The processes can include exposing a polyester composition to one or more glycols to depolymerization conditions thereby providing one or more depolymerization products. The one or more depolymerization products can be exposed to an alcoholysis process to recover dialkyl terephthalate.

Abstract: Processes and facilities for recovering and purifying a pyrolysis gas formed by pyrolyzing waste plastic are provided. The purification process may comprise one or more treatment processes, including a caustic scrubber process, which may be included in a cracker facility or separate from the cracker facility. The resulting gas effluent stream from the caustic scrubber is particularly useful for recovering recycled chemical products and co-products from a downstream cryogenic separation process.

Abstract: A heat integration process and system for a chemical recycling facility is provided that can lower the carbon footprint and global warming potential of the facility. More particularly, one or more heat transfer media may be used to recover heat energy from a waste plastic pyrolysis effluent and redistribute the recovered heat energy throughout the chemical recycling facility. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the heat integration process and system herein.

Abstract: Various processes and configuration are provided for a chemical recycling facility that can lower the carbon footprint and global warming potential of the facility. More particularly, we have discovered numerous ways for reducing the carbon footprint of the facility by: (i) recycling at least a portion of the residual heat energy from the pyrolysis effluent back upstream to the pyrolysis process and waste plastic liquification stage; (ii) recovering at least a portion of the carbon dioxide from at least a portion of the pyrolysis flue gas and/or the pyrolysis gas; (iii) feeding at least a portion of the pyrolysis gas at a cracker facility at a position downstream of a cracker furnace; (iv) using at least a portion of a demethanizer overhead stream as a fuel in a pyrolysis facility and/or a cracking facility; and (v) providing a chemical recycling facility that contains a pyrolysis facility co-located with a cracking facility. Thus, the global warming potential of the chemical recycling facility may be optimized and lowered due to the processes and configurations described herein.

Abstract: Processes and facilities for providing recycled content hydrocarbon products (r-products) from the pyrolysis of waste plastic are provided. Processing schemes are described herein that increase energy efficiency and help reduce overall environmental impact while producing valuable final products from chemically recycled waste plastic. Use of recycled content and/or high hydrogen content fuel in one or more process furnaces also reduces global warming potential of the facility by reducing carbon emissions, while also improving energy integration.
