Students from St. Petersburg and Dzerzhinsk are semi-finalists of the CASE–IN championship

The qualifying stage of the International Engineering CASE-IN Championship in the field of Petrochemistry was held on the site of the Dzerzhinsk Polytechnic Institute of the R.E. Alekseev NSTU in a remote format.

Welcoming the participants and experts, members of the organizing committee of the championship, Alexander Petrovsky, Director of the DPI NSTU, noted the growing prestige of the competition: it was no coincidence that 12 teams participated in the selection of 2025 – more than last year. These are teams from Dzerzhinsky Polytechnic Institute, Nizhny Novgorod State Technical University named after R.E. Alekseev, St. Petersburg Mining University, Astrakhan State Technical University. Alexander Mikhailovich wished the participants of the stage a successful case defense and high marks from the expert commission.

The topic of the "Petrochemistry" case this year was devoted to the development of technological solutions to reduce isobutylene losses. The task of the participants was to analyze the existing technological process of isobutylene production at the production of PJSC Nizhnekamskneftekhim (part of Sibur Holding). The aim was to reduce the loss of raw materials in the cubic flow of the K-145 distillation column.

According to Igor Balakhnin, an expert of the qualifying stage, PhD, Associate professor of the Department of TOC, a distinctive feature of this year "was the practice of using the Aspen Hysys software product by the teams. The most popular solution was to replace the internal contact devices of the distillation column."

As a result of the teams' performance, two teams advanced to the next stage of the championship - the semifinals - the SCT Project team from St. Petersburg Mining University, which took 1st place, and the Spare Parts team from Dzerzhinsk Polytechnic Institute, which showed the best result during the qualifying stage from the teams of Dzerzhinsk polytechnics.
