Case Study: Reliance Industries Limited achieves $2.4M/year savings with Aspen Technology's Aspen Plus

Reliance Industries Ltd Troubleshoots with Aspen Plus and Saves $2.4M USD per Year

Reliance Industries Limited faced an urgent toluene-separation challenge after an offsite processing shutdown left its benzene/toluene unit underperforming—the benzene bottoms exceeded the 200 ppm spec and the column proved hydraulically limited. To avoid heavy losses and a costly rebuild, Reliance turned to Aspen Technology and its aspenONE suite, using Aspen Plus to diagnose and model the problem quickly in-house.

Using Aspen Technology’s Aspen Plus, Reliance matched a rigorous model to plant data, identified poor tray efficiency (55% vs. 76%), and reconfigured a redundant column as a stripper along with feed-temperature and control optimizations. The Aspen Technology–driven solution was implemented with minimal capital outlay, met predicted performance, improved product quality and production, and delivered savings of $2.4M USD per year while avoiding external consulting delays and costs.
