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.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various e-waste sources into Clean Fuel Gas and Char source are disclosed. The invention processes e-waste sources, such as for example whole circuit boards, to effectively shred and/or grind the waste source, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source, along with the ability to recover precious metals and other valuable components from the Char.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various carpet, rug, polymeric materials and other waste sources, such as solid waste, tires, manure, auto shredder residue, glass and carbon fiber composite materials, municipal solid wastes, medical wastes, waste wood and the like into a Clean Fuel Gas and Char source are disclosed. The invention processes the carpet, rug, polymeric material to effectively shred and/or grind the waste source, such as post-consumer carpet remnants and waste, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source. Additional waste sources, such as solid waste, tires, manure, auto shredder residue, glass and carbon fiber composite materials, municipal solid wastes, medical wastes, waste wood and the like, are suitable for the processing of the invention disclosed.

A method of forming a syngas for producing liquid hydrocarbons, the method comprising: providing a feed gas comprising carbon dioxide, hydrogen and compounds of sulfur; providing a carbon-monoxide-enriched feed gas by passing the feed gas to a reverse-water-gas-shift reaction chamber to convert a portion of the carbon dioxide and a portion of the hydrogen to carbon monoxide and water, and to convert at least a portion of the compounds of sulfur to hydrogen sulfide; passing the carbon-monoxide-enriched feed gas to a carbon-dioxide-removal unit to provide the syngas and a carbon-dioxide-enriched stream, the carbon-dioxide-enriched stream comprising carbon dioxide and hydrogen sulfide; providing a purified carbon-dioxide stream by passing the carbon-dioxide-enriched stream to a hydrogen-sulfide-removal unit to remove hydrogen sulfide from the carbon-dioxide-enriched stream; and recycling the purified carbon-dioxide stream into the feed gas.

A gasification system includes a scrubber in communication with a particulate removal subsystem and a quench sub-system.
