Fortune has successfully completed the commissioning of its 600 TPD LNG Cold Energy Liquid Air Separation Unit (ASU) in Tianjin — a key milestone toward full commercial operation.
The project integrates LNG regasification cold energy as the primary refrigeration source for the ASU, replacing conventional electric-driven refrigeration and significantly improving overall energy efficiency.
Key technical highlights include:
• LNG cold energy recovery and transfer integration
• Ethylene glycol circulation system
• Optimized air compression and molecular sieve purification
• High-efficiency cryogenic distillation system
• Coordinated multi-system control for stable operation
To ensure smooth commissioning before LNG supply became available, the team adopted liquid nitrogen as a temporary cold source to simulate real operating conditions — successfully validating system reliability and accelerating the startup process.
With over 40 years of cryogenic engineering experience, Fortune is among the few companies capable of independently delivering ultra-large ASUs above 100,000 Nm³/h, supported by full lifecycle capabilities covering R&D, engineering, manufacturing, installation, and O&M.
This project further strengthens Fortune’s expertise in:
▪ LNG cold energy utilization
▪ Energy-efficient cryogenic systems
▪ Modular integration and process optimization
▪ Low-carbon industrial gas solutions
Fortune remains committed to advancing efficient and sustainable cryogenic technologies for the global energy industry.
