HAR Management: Two Solutions2. Adapt (by Advanced

Control)1. Mitigate (by Hardware

Modification)

To mitigate the cause(s) of Hot Air Recirculation by means of

Technology to improve LNG production capacity

To adjust (adapt) operation in real time manner to cope with HAR by means of HAR Digital to push LNG production to the limit

Air Flow Vector Analysis

Hot Spot Analysis

CFD Simulation is a powerful tool for JGC to visualize hotspots, air flow behavior inside the plant (for both design phase and operation phase). Not only that, it can be used to evaluate the plant modification without needing to implement it.

Copyright 2019 JG



JGC has been able to apply their extensive knowledge and experience through R&D program in AIRLIZE LNG ® to establish an advanced control scheme to over-come the HAR issues.

The Feed-forward process control powered by HAR Predictive Model allows you to realize the full benefit of the motor power which will enhance your LNG throughput by at least 3~5% without any major modification to your facility

Key success factors of the Technology- Introduction of the Real time Weather Monitoring System- Process Big Data Analysis, CFD Simulation, and Rigorous Process Simulation- JGCʼs extensive experience in LNG processes and Hot Air Recirculation Analysis
