  • Publication number: 20220081376
    Abstract: Disclosed herein is a process for upgrading a raffinate butene (C4 Raffinate) stream to propylene which can produce polymer grade propylene (PGP) by a metathesis process, without consuming fresh ethylene as a feedstock. By recycling ethylene byproduct in the metathesis equilibrium, propylene selectivity can be further improved without negatively impacting butene conversion. Additionally, upon PGP separation, this technology can provide an effluent acceptable for alkylate production by achieving a balanced butene conversion and heavies coproduction. The disclosed process is a relatively low temperature process which can be deployed as a drop-in option for conventional ethylene/butene metathesis unit and provide additional flexibility to existing operations to balance the supply and demand of C2-C4 light olefins.

  • Patent number: 11270121
    Abstract: The technology described herein is directed to a media indexer framework including a character recognition engine that automatically detects and groups instances (or occurrences) of characters in a multi-frame animated media file. More specifically, the character recognition engine automatically detects and groups the instances (or occurrences) of the characters in the multi-frame animated media file such that each group contains images associated with a single character. The character groups are then labeled and used to train an image classification model. Once trained, the image classification model can be applied to subsequent multi-frame animated media files to automatically classifying the animated characters included therein.
