    摘要: A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are separated from the isoolefins and disproportionated with ethylene to form a propylene product, while the thus separated isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene product.

    摘要: A process for producing propylene and 1-butene is disclosed. The process comprises dimerizing ethylene in the presence of a dimerization catalyst to produce a dimerization mixture comprising 1-butene and 2-butenes. The dimerization mixture is distilled to produce a 1-butene stream containing 1-butene and ethylene, a 2-butenes stream, and a heavy stream. The 2-butenes stream is reacted with ethylene in the presence of a metathesis catalyst to produce a metathesis mixture comprising propylene, ethylene, and 2-butenes. Propylene is separated from the metathesis mixture.

    摘要: A process for cracking a heavy hydrocarbon feed is disclosed. The heavy hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted intimately with a countercurrent steam to produce a second vapor stream and a second liquid stream. The second vapor stream is contacted with a wash liquid in a rectification section to form a rectified stream. The first vapor stream and the rectified stream are cracked in the radiant section of the steam cracker to produce a cracked effluent.

    摘要: Ethylene separation processes are described herein. The ethylene separation processes generally include introducing a feed stream including ethylene and butene into a de-ethenizer; and separating the ethylene from the butene via fractional distillation within the de-ethenizer to form an overhead stream including separated ethylene and a bottoms stream including separated butene, wherein the de-ethenizer operates at a pressure of less than 350 psig.
