  • Publication number: 20220402840
    Abstract: This process comprises quenching and washing with water a gas stream derived from pyrolysis, and separating an aqueous phase from a washed gas stream; compressing, then cooling a washed gas stream; washing the compressed gas stream under pressure; passing the washed gas stream through at least one acid removal unit; drying the acid-depleted gas stream; passing the dry gas stream through at least one impurity removal unit; and feeding the purified gas stream into a cryogenic absorption unit and supplying the cryogenic absorption unit with a hydrocarbon cryogenic solvent to obtain a light gas residue, and a fraction of C2+ hydrocarbons.

  • Patent number: 11401221
    Abstract: A method for producing a stream of propylene and associated facility are described. The method includes: an introduction of a feed cut rich in C4 and/or C5 hydrocarbons, and at least one cut rich in ethylene into a metathesis reactor; an introduction of a metathesis product in a deethylenizer; a production of an overhead stream rich in ethylene and a feed stream; an introduction of the feed stream into a depropylenizer and recovery of a bottom stream containing C4+ hydrocarbons; a recovery, from an overhead stream of the depropylenizer, of the propylene stream; a lateral withdrawal of a recycle stream and return of the recycle stream to the metathesis reactor; a lateral draw-off, in the depropylenizer, of a purge rich in C4 paraffinic hydrocarbons and/or rich in isobutene.

  • Publication number: 20200071245
    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.
