  • Patent number: 10876054
    Abstract: A process and apparatus for making aromatics are described. The process includes reforming a naphtha stream in a reforming zone to form a reformer effluent comprising aromatic compounds and non-aromatic compounds, wherein at least a portion of the aromatic compounds contain alkyl groups. The reformer effluent is heated and passed directly to an acid cracking reaction zone. The non-aromatic compounds are selectively cracked and at least a portion of the alkyl groups on the aromatic compounds are selectively dealkylated in the presence of an acid cracking catalyst to form a cracked reformer effluent comprising the aromatic compounds and cracked olefins.

  • Publication number: 20200001198
    Abstract: Process for separating a highly pure propylene product from a liquefied petroleum gas stream is disclosed, which eliminates a C3 splitter having over 120 trays and the additional equipment that a C3 splitter requires. The process includes passing a feed stream to a dividing wall column to produce an overhead stream, a first side draw stream, a second side draw stream, and a product stream. The first side draw stream is passed to a treatment unit to produce a treated stream. The treated stream is passed to a membrane unit and a permeate stream is passed from the membrane unit to produce a polymer grade propylene stream.
