Abstract: Process of treating a net gas stream is disclosed. The process includes sending the net gas stream to a compressor to produce a compressed gas stream. The compressed gas stream is then sent to a pressure swing adsorption unit to produce a hydrogen product stream and a tail gas stream. Tail gas stream from the pressure swing adsorption unit is sent to a first membrane unit to produce a first permeate stream and a first non-permeate stream. Portion of the tail gas stream is sent to a second membrane unit to produce a second permeate stream and a second non-permeate stream.

Abstract: Processes and apparatuses for producing aromatic compounds from a naphtha feed stream are provided herein. In an embodiment, a process for producing aromatic compounds includes heating the naphtha feed stream to produce a heated naphtha feed stream. The heated naphtha feed stream is reformed within a plurality of reforming stages that are arranged in series to produce a downstream product stream. The plurality of reforming stages is operated at ascending reaction temperatures. The naphtha feed stream is heated by transferring heat from the downstream product stream to the naphtha feed stream to produce the heated naphtha feed stream and a cooled downstream product stream.

Abstract: A process for adsorbing hydrogen chloride (HCl) from a regeneration vent gas. The regeneration vent gas is cooled from a catalyst regeneration zone. The cooled regeneration vent gas is passed to an adsorption zone that is spaced apart from the catalyst regeneration zone. HCl from the regeneration vent gas is adsorbed onto a sorbent in the adsorption zone to enrich the sorbent with HCl to provide HCl-rich sorbent and deplete HCl from the regeneration vent gas to provide HCl-lean regeneration vent gas. HCl-lean regeneration vent gas is purged as an effluent gas. HCl-rich sorbent is passed from the adsorption zone to a sorbent regeneration zone. HCl from the HCl-rich sorbent in the sorbent regeneration zone is desorbed to provide a regenerated sorbent. The regenerated sorbent is transferred to the adsorption zone.

Abstract: Processes for separating conjunct polymer from an organic phase are described. A mixture comprising an ionic liquid phase and the organic phase into the ionic phase and an organic phase comprising the conjunct polymer and at least one silyl or boryl compound. The organic phase is separated in a fractionation column into an overhead fraction comprising unreacted silane or borane compound and a bottoms fraction comprising the conjunct polymer and the silyl or boryl compound. The bottoms fraction is passed through an adsorption zone, and the silyl or boryl compound is recovered. Alternatively, the organic phase is passed through an adsorption zone first to remove the conjunct polymer and then a fractionation zone to separate the unreacted silane or borane compound from the silyl or boryl compound.

Abstract: A flow connector creates a fluid connection between a port in a wall of a reactor vessel and an axial flow path of the reactor vessel. The flow connector has a wall defining a flow path of the flow connector. The flow path terminates in a first end opening and a second end opening. The first end opening is configured to connect to the axial flow path of the reactor vessel, and the second end opening is configured to connect to the port in a wall of the reactor. The flow connector includes a passageway extending through the wall of the flow connector to provide access to the flow path of the flow connector. A cover is dimensioned for sealing the passageway. The passageway may be dimensioned such that a person may traverse the passageway to access the flow path of the flow connector.

Abstract: A process and apparatus for removing oxygenates from a petroleum stream of C3 and/or C4 hydrocarbons comprises water washing the petroleum stream to absorb oxygenates to provide a hydrocarbon stream lean in oxygenates and a water stream rich in oxygenates. The water stream is stripped to remove oxygenates into an oxygenate concentrated stream and an oxygenate-lean water stream. The lean water stream can be recycled to the water wash column.

Abstract: The process removes hydrogen sulfide from hydrotreated gas by TSA. Hydrogen sulfide adsorbs on the adsorbent while allowing hydrogen in the hydrotreated gas to pass the adsorbent to provide a desulfided hydrogen gas stream and a sulfided adsorbent. A regenerant gas stream can be contacted with the sulfided adsorbent at a swing temperature to desorb hydrogen sulfide from the adsorbent into the regenerant gas stream. The regenerant gas stream can then be recycled to a hydrotreating reactor for processing biorenewable feed to provide hydrogen sulfide to the reactor. The desulfided gas stream can be purified to remove impurities such as carbon oxides and recycled to the hydrotreating reactor and/or used as the regenerant gas stream.

Abstract: The process produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The recycle gas is recycled to the hydrotreating reactor without removing hydrogen sulfide, which is needed in the biorenewable feed to keep the hydrotreating catalyst active. A purification unit can be utilized on a purge gas stream to purify the gas and improve hydrogen concentration in the recycle gas when added to the recycle gas.
