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 process for making recycle content ammonia by reacting hydrogen with nitrogen. At least a portion of the hydrogen is obtained directly or indirectly by molecular reforming a mixed plastic waste or pyrolysis product feedstock. The molecular reforming can be a steam reforming process or a partial oxidation process, such as a partial oxidation gasifier, to generate the syngas used as a source of hydrogen. The recycle content associated with the ammonia can be obtained from the mixed plastic waste, the recycle content in the pyrolysis product, such as pyoil or pygas, or the recycle content in the syngas or the purified hydrogen stream from the syngas.

Abstract: A method of producing synthesis gas is provided. The method includes feeding a waste plastic feedstock into a partial oxidation gasifier. The waste plastic feedstock includes one or more vitrification materials. The method also includes partially oxidizing the waste plastic within the partial oxidation gasifier to produce the synthesis gas.

Abstract: Chemical recycling facilities for processing mixed plastic waste 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 generation/energy production 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.

Abstract: Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

Abstract: A composition having a recycle content value is obtained by reacting a recycle content feedstock to make a recycle content alpha olefin or by deducting from a recycle inventory a recycle content value applied to an alpha olefin composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by an alpha olefin manufacturer has its origin in recycled waste and/or pyrolysis of recycled waste and/or in thermal steam cracking of recycle content pyoil.
