Improve material balance in high-purity distillation control
Using dual-composition conserved energy efficiency, reduced reprocessing and allowed higher throughput
In this case history, a petrochemical facility needed to improve operation control as well as profitability for a benzene-toluene-xylene (BTX) distillation train. The project focused on dual-composition material balance controls. Improved process control from the new control system provided an annual $1 million in energy savings and reduced feedstock reprocessing needs.
Dual-composition material-balance control strategies were successfully implemented and commissioned for heat-integrated high-purity distillation towers at a petrochemical facility by using Shinskeys methodology as guidance in the strategy selection.
