A process for converting pyrolysis effluent stream into hydrocarbon products. Waste plastics are pyrolyzed at high temperature in a pyrolysis reactor to obtain a plastic pyrolysis effluent stream. The plastic pyrolysis effluent stream is further sent to a steam cracking unit for the separation of plastic pyrolysis effluent stream into a C5+ hydrocarbon stream and a C4 hydrocarbon stream. The pyrolysis reactor is operated at a to obtain hydrocarbon products of high value.

Integrated process for pyrolysis and steam cracking

Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H-rich stream and a first liquid phase hydrocarbon stream. The H-rich stream may be contacted with an adsorbent to form an H-ultra rich stream and a gas stream. C/Chydrocarbons are absorbed from the gas stream with the liquid phase hydrocarbon stream. The gas stream may be contacted with an H/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H-rich permeate stream and an Hdepleted non-permeate residue stream.

Processes for recovering LPG from a reforming-zone effluent

Processes and apparatuses for alkylating aromatic hydrocarbons with an alkylating reagent to produce an alkylated aromatic product are described. The processes and apparatuses use a riser reactor operated at a superficial velocity of 10 m/s to 25 m/s to produce the alkylated aromatic product. In some embodiments, a combination of steam and aromatic hydrocarbon is used to lift the catalyst.

Aromatic alkylation process

Processes and apparatuses for para-xylene separation. A stream of para-xylene is separated from a toluene stream in a fractionation column. An overhead stream of the fractionation column is compressed and then passed to a heat recovery zone to transfer heat from the overhead stream to another process stream in, for example, a heat exchanger. The fractionation column may be separating an effluent from a toluene methylation reactor.

Processes for separating para-xylene from toluene

It is desirable to provide improved processes and apparatuses for methylation of aromatic compounds such as toluene and benzene in an aromatics complex. Described herein are processes and apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, processes and apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex.

This present disclosure relates to processes and apparatuses for use of a single dividing wall distillation column for phenol fractionation. More specifically, the present disclosure relates to processes and apparatuses for phenol fractionation by combining crude acetone column and cumene-AMS column into a single dividing wall distillation column. The proper allocation of steam or water injection, chemical treatment reactor and internal liquid phase separator, the positioning of the side draw enables high yield of acetone and phenol.

Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is compressed, partially condensed and cooled to form a partially condensed, compressed net gas phase stream. The partially condensed, compressed net gas phase stream is separated to form an intermediate gas phase stream. The intermediate gas phase stream is cooled to form a cooled intermediate gas phase stream. The liquid phase hydrocarbon stream is cooled to form a cooled liquid phase hydrocarbon stream. The cooled intermediate gas phase stream is contacted with the cooled liquid phase hydrocarbon stream to form an H-rich stream and a cooled second intermediate liquid phase hydrocarbon stream that is enriched with C/Chydrocarbons.

The invention involves a process for treating a gas stream from a hydroprocessor that contains hydrogen, methane and C+ hydrocarbons. In embodiments of the invention, the gas stream is sent through at least two pressure swing adsorption units to produce a high quality hydrogen stream, a fuel gas stream containing most of the methane and a tail gas stream that is sent to a steam cracker. Lean gas from a gas plant and other refinery off gases may also be processed together with the gas stream from the hydroprocessor.
