Saudi-European petrochemical company Sabic Ibn Zahr has recently awarded US-based Honeywell, a contract for setting up an automation project at its Jubail facility.
The project involves the implementation of advanced process control solutions on two Unipol polypropylene units.
Honeywell Profit NLC is a unique control and optimisation solution designed specifically for the polymer industry. It controls nonlinear processes in both process gains and process dynamics. A rigorous process model describes process equipment geometry and chemical kinetics, and eliminates the need to step-test the plant. This model also combines the advantages of reliable multivariable control and optimisation of on-line process and dynamic off-line simulation for new product grades. Profit NLC delivers many benefits, including: improvement in plant throughput during periods of high polymer demand and plant constraints; reduction in grade transition times and process upsets; and increased operational stability.
