A naphtha hydrotreating process involves the use of a sulfur guard bed (SGB) with a controlled bypass which allows for control of the sulfur in the feed to a downstream processing unit. The SGB is installed on the light ends stripper bottoms stream in a naphtha hydrotreating unit.

An improved isomerization process in which the inlet temperature to the isomerization reaction zone is less than 105&#xb0; C. is described. A separate reactor is provided for the decomposition of the organic chloride. The product of the decomposition of the organic chloride is sent to an isomerization reactor along with a hydrocarbon feed containing paraffins. The use of the organic chloride decomposition reactor allows the operating temperatures for the isomerization reaction zone to be reduced.

The present subject matter relates to methods and apparatuses for the continuous preparation of a cumene feed for a cumene oxidation process. More specifically, the subject matter relates to a process for passing a cumene alpha-methylstyrene stream through a caustic wash column having an integrated water wash section for the removal of organic acids.

Methods and apparatuses for treating an organic feed

Byproduct formation in aromatic alkylation processes is reduced when different polyalkylated aromatic compounds are first fractionated into separate streams enriched in these respective polyalkylated aromatic compounds, and the separate streams are sent to different transalkylation reaction zones, which may or may not be in the same reactor. The different transalkylation reaction zones allow for greater control of the transalkylation of the respective polyalkylated aromatic compounds, such as diisopropylbenzene (DIPB) and triisopropylbenzene (TIPB) that accompany the alkylation of benzene with propylene in a process for cumene production.

Aromatic alkylation process with reduced byproduct formation

Processes and systems for treating an aromatic feed comprising an aromatic component and nitrogen-containing impurities, as well as processes and systems for preparing a reaction product of an aromatic component from an aromatic feed comprising the aromatic component and nitrogen-containing impurities, are provided herein. In an embodiment, a process for treating an aromatic feed comprising an aromatic component and nitrogen-containing impurities includes adsorbing a portion of the nitrogen-containing impurities from the aromatic feed to produce a treated aromatic feed comprising the aromatic component and residual nitrogen-containing impurities. The treated aromatic feed and water are mixed to produce a hydrated aromatic feed. A purified aromatic feed and a water component are distilled from the hydrated aromatic feed in a distillation stage, wherein the water component comprises residual nitrogen-containing impurities from the treated aromatic feed and wherein the purified aromatic feed comprises the aromatic component.

A process for the decomposition of a cumene oxidation product mixture to produce phenol and acetone with reduced by-product formation by introducing the cumene oxidation mixture into an inlet of a decomposing vessel containing indirect heat exchange surfaces wherein the cumene oxidation product mixture and a circulating stream are admixed, reacted and cooled by passage around the indirect heat exchange surfaces.

Decomposition of cumene hydroperoxide
