A process for the treatment of waste water, spent air, and hydrocarbon containing liquid and gaseous streams in the cumene/phenol complex is described. Various effluent streams are combined in appropriate collection vessels, including a spent air knockout drum, a hydrocarbon buffer vessel, a fuel gas knockout drum, a phenolic water vessel, and a non-phenolic water vessel. Streams from these vessels are sent to a thermal oxidation system.

Cumene-phenol complex with thermal oxidation system

Processes and apparatus for analyzing fluid properties of a stream are described. The processes utilize a simulated moving bed system and a rotary valve. The processes involve sending a portion of the pump-around stream to a side chamber where the moisture content of the adsorbent in the side chamber or one or more fluid properties of the stream or both are measured using an analyzer specific to each fluid property.

The present invention relates to the fractionation technology that is used to create purified phenol and acetone products. More specifically, the present invention relates to a fractionation technology that is used to create crude acetone and crude phenol streams using a dividing wall column intended to remove cumene, alpha-methyl styrene and water from the product side of the wall.

The present invention relates to process and apparatus for removing aldehydes from acetone. More specifically, the present invention relates to a process and apparatus for removing aldehydes from acetone by reacting the aldehydes with caustic in an acetone column and washing the organic phase with a plurality of water streams.

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.

Methods and apparatuses for phenol fractionation in a single dividing wall column

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

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.
