  • Methods and systems for producing pressware
    Patent number: 11919270
    Abstract: A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

  • Recovery of light olefins from dry hydrocarbon gas from refinery and petrochemical production processes for production of alkylate
    Patent number: 11905241
    Abstract: Methods and systems for treating an olefin-containing stream are disclosed. The disclosed methods and systems are particularly suitable for treating an off-gas stream in a refining or petrochemical process, such as from a fluid catalytic cracker (FCC), coker, steam cracker, and the like. The stream is treated in an absorber column to reject lighter stream components and to absorb ethylene and/or propylene into a solvent. The solvent is typically isobutane. The enriched solvent stream from the absorber column is fed to an alkylation reactor, which reacts the dissolved olefin with the isobutane solvent to produce an alkylate product.
