ABB has won an order from JG Summit Petrochemical Corporation to supply electrical and process power management systems for its petrochemical expansion project. The project will increase cracker production of ethylene by 50 per cent to 480,000 tpa and propylene by 26 per cent to 240,000 tpa. The new bimodal polyethylene plant will reach a capacity of 250,000 tpa and the capacity of the existing polypropylene plant will be upgraded to 300,000 tpa from current 190,000 tpa.
ABB will design, engineer, manufacture, and supply a complete plant electrification system for the proposed expansion. The scope of supply includes 69kV high voltage air-insulated switchgear, UniGear medium-voltage switchgear, MNS low-voltage switchgear, power and distribution transformers, a capacitor bank, soft starter, IS-limiters and a process power management system. This software-based solution seamlessly integrates with ABB AbilityTM 800xA process and electrical control systems to ensure a reliable and stable electricity supply.
“It’s great news that JG Summit Petrochemical has chosen ABB as its partner for this important project,” said Zeng Tao, ABB’s Singapore Hub Business Unit manager. “Our extensive experience in global deliveries for petrochemical plants will hold us in good stead to deliver a robust and reliable solution for this plant.”
The expansion will require a sophisticated electrical network solution due to the inter-meshing of power systems from the existing plant and the new extension. This creates a higher risk for high short-circuit currents. ABB’s IS-limiters, an advanced fault current limiter solution, is being introduced to provide effective protection and limit the fault currents during the first rise within less than a quarter cycle.
To further increase the reliability and efficiency of the plant, ABB’s process power management system, using ABB AbilityTM 800xA, is being implemented to provide control and monitoring of the complete electrical network. Its inherent predictive and intelligent multi-layer fast load shedding application provides prevention against power disruption, ensuring a stable power source.
