Title: Dennis J. Stanley: Innovator in Aromatics Production

Introduction

Dennis J. Stanley is a notable inventor based in Houston, TX, with a focus on innovations in the field of aromatics production. He holds a total of 5 patents that contribute significantly to the chemical engineering industry. His work primarily revolves around processes that enhance the efficiency of para-xylene production.

Latest Patents

Among his latest patents is an innovative process for producing para-xylene. This process involves supplying a feed comprising Caromatic hydrocarbons to a dividing wall distillation column. The column separates the feed into various streams, including a Caromatic hydrocarbon-containing stream. This stream is then directed to a para-xylene recovery unit, where para-xylene is extracted, resulting in a para-xylene depleted stream. This depleted stream is subsequently treated with a xylene isomerization catalyst to isomerize xylenes, producing an isomerized stream that is recycled back to the recovery unit.

Another significant patent by Stanley is an apparatus for the production of xylenes. In this process, a feed stream containing Caromatic hydrocarbons is separated into a toluene-containing stream and other hydrocarbon streams. The toluene-containing stream is treated with a methylating agent to convert it into xylenes, generating a methylated effluent stream. Para-xylene is then recovered from both the Caromatic hydrocarbon-containing stream and the methylated effluent stream. The resulting para-xylene depleted stream is treated with a xylene isomerization catalyst under liquid phase conditions, leading to the production of an isomerized stream.
