Case Study Next Generation of Advanced Process Control Delivers Benefits for Ethylene ManufacturerCHALLENGE Revamp APC controllers to enable higher throughput and a consistent supply of high-quality ethylene, despite a fluctuating ethane feed and no full-time, dedicated APC personnel. SOLUTION Qenos used Aspen DMC3TM to update models while actively controlling the unit and driving it towards an optimal operating point. BENEFITS • More accurate models led to enhanced APC benefits of production, yield and energy efficiency • APC models were updated with no disruptions to the process • Adaptive Process Control technology eliminated tedious workflows, freeing up APC resources for more valuable tasks • Much greater operator acceptance and improved APC utilization • Integrated and
