October 29, 2018 - ABB has won an order from JG Summit Petrochemical Corporation, a subsidiary of JG Summit Holdings, Inc., to supply electrical and process power management systems for its petrochemical expansion project. The project will increase cracker production of ethylene by 50% to 480,000 tpa and propylene by 26% 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 integrates with ABB Ability 800xA process and electrical control systems to ensure a stable electricity supply. 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, a fault current limiter solution, is being introduced to provide protection and limit the fault currents during the first rise.
ABB’s process power management system, using ABB AbilityT 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.
