Embodiment Construction

[0014]The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0015]Processes and systems for treating an aromatic feed that includes an aromatic component and nitrogen-containing impurities, as well as processes and systems for preparing a reaction product of an aromatic component from the aromatic feed, are provided herein. Referring to FIG. 1, the processes employ adsorption (STEP 12) to remove a portion of the nitrogen-containing impurities from the aromatic feed, followed by mixing (STEP 14) the resulting treated aromatic feed with water to produce a hydrated aromatic feed and distilling (STEP 16) a purified aromatic feed from the hydrated aromatic feed. Residual nitrogen-containing impurities are included in the water component that is distilled ...

Abstract

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.

Description

TECHNICAL FIELD[0001]The present invention generally relates to processes and systems for treating an aromatic feed that includes an aromatic component and nitrogen-containing impurities, as well as processes and systems for preparing a reaction product of an aromatic component from the aromatic feed. In particular, the present invention relates to processes and systems for removing nitrogen-containing impurities from the aromatic feed.BACKGROUND[0002]Reaction products of aromatic compounds, such as alkylated aromatic compounds, are common petrochemical products that are useful as intermediates for the preparation of other widely-used industrial compounds. For example, cumene (also known in the art as isopropyl benzene) is widely used as an intermediate in the production of phenol and acetone, and ethylbenzene is widely used as an intermediate in the production of styrene.[0003]Alkylated aromatic compounds are generally prepared by reacting aromatic compounds with olefins in the pre...
