Solvay Sodi

Solvay Sodi's Bulgarian chemical plant needed to upgrade a steam generation facility to deliver greater control, more reliable operation, less downtime, and reduced energy consumption. The existing system lacked adequate control capabilities for boiler airflow optimization.

Allen-Bradley PowerFlex 7000 variable frequency drives were deployed with commissioning by a Rockwell Automation medium voltage field engineer, plus pre-commissioning support and remote support capability.

Electricity consumption was reduced by 20%—equivalent to 22 MWh per day. Improved access to operational data enabled tighter control of boiler airflow. Reduced stresses on equipment resulted in longer life and reduced maintenance costs.

• Medium-voltage VFDs on steam generation assets deliver some of the largest energy savings available in chemical plant operations • Real-time operational data access enables process fine-tuning that further amplifies initial energy reduction gains • Reduced mechanical stress from VFDs extends asset life, creating a second wave of value beyond direct energy savings
