"The adsorption tower pressure is stable, and fluctuations in feed composition remain within controllable limits; the optimization plan has proven effective." On May 18, operators on duty at the control room of Liaoyang Petrochemical’s aromatics complex reported these real-time parameters. By adjusting material flow paths over the first four months of the year, the company achieved a 4.1% year-on-year increase in cumulative paraxylene production—setting a five-year record—and made a significant breakthrough in its drive to improve quality and efficiency.
Since the beginning of the year, facing a shortage of mixed-xylene feedstock, Liaoyang Petrochemical has steadfastly adhered to the principle that "great stability yields great benefits." Without altering the existing operational model, the company closely monitored feedstock specifications, precisely adjusted key parameters, and strengthened profitability analysis across the entire process, thereby continuously boosting paraxylene yields and operational efficiency. Technical staff intensified refined process control and implemented special monitoring and anomaly management for critical machinery, ensuring the unit maintained stable, high-output performance even under high-load conditions. Meanwhile, initiatives such as "Red Flag Team" competitions and operational process optimizations fully motivated frontline staff, helping to resolve key issues affecting long-cycle operations and driving continuous improvement in production metrics.
