Title: Innovations of Sergey A. Polyakov in Petrochemistry

Introduction

Sergey A. Polyakov is a notable inventor based in St. Petersburg, Russia. He has made significant contributions to the field of petrochemistry, particularly in the extraction of phenol from phenol tar. His innovative methods have implications for the efficient production of phenol and acetone.

Latest Patents

One of Sergey A. Polyakov's key patents is titled "Method of phenol extraction from phenol tar." This invention is particularly relevant in the combined production of phenol and acetone by the cumene method. The method is a two-stage process that minimizes wastewater volume, reduces equipment corrosion, and decreases the consumption of cumene. In the first stage, phenol tar is treated with a 2-5% water solution of a water-soluble amine at a specific ratio to produce two layers: water and organic. The second stage involves thermotreatment of the water layer, leading to the decomposition of water-soluble amino phenate into amine and phenol. The gaseous amine is then removed and recycled back to the first stage, while the phenol water solution obtained is extracted using standard agents.
