In 2012, Zeeco successfully installed a Zeeco QFSC Steam Assisted Flare System for LG Chemicals petrochemical plant in South Korea. Zeeco worked closely with the EPC company, LG / Toyo Korea, to ensure the flare’s proper design, full fabrication, field assembly, and erection / start-up for the facility.

Another challenge was to meet equipment fabrication and installation completion deadline within an eight-month timeframe. Zeeco fabricated and supplied the following equipment:

  • 120m Flare Stack
    • Integral Liquid Seal Drum in Stack Base
    • Buoyancy Type Purge Gas Seal Device
  • 120m Derrick Support Structure for Flare Stack
  • Set of Ladders and Platforms
  • Retractable Davit System
  • QFSC Flare Tip with 4 Pilots
  • Front Flame Generator (FFG) Rack with Control Panel
  • Fixed Aircraft Warning Light System with Control Panel
  • Utility Piping
  • Interconnecting Piping between the Flare Stack and FFG Rack

Although there were several last minute changes made during installation in the field, Zeeco was able to promptly work with installers to make the necessary changes required for proper installation. We were also able to help meet LG Chemicals start-up deadline by assisting with start-up issues due to pilot gas composition. The pilot’s fuel gas composition contained an inordinate amount of hydrogen, causing problems with pilot ignition. Zeeco personnel made the required adjustments and changes in the field to accommodate the varying fuel gas possibilities for the job. This resulted in a combustible gas/air mixture range, solving the pilot’s ignition issue.
