  • Liquid isomerization for methathesis process
    Patent number: 12030849
    Abstract: The present disclosure relates to processes for improved yields of propylene via metathesis, primarily from the conversion of C4 and C5+ olefins obtained from steam or fluid catalytic cracking of hydrocarbons. In particular, the present disclosure relates to processes for preparing propylene by improved isomerization of 1-butene to 2-butene relative to the metathesis reaction.
    Type: Grant
    Filed: February 13, 2018
    Date of Patent: July 9, 2024
    Assignee: TECHNIP PROCESS TECHNOLOGY, INC.

  • Process for recovering phenol from a BPA waste stream
    Patent number: 7858830
    Abstract: An improved process for recovering phenol from a bisphenol-A residue stream by reconfiguring the distillation column and the cracking reactor in a way that separates the reboil/distillation heat load and the cracking heat load, so that separate heat sources are used.
    Type: Grant
