LNG QRS Automating Volume Measurement Software
Essential Features of LNG-Quality Release System
Software solution for efficient LNG loading operations
- Real-time LNG quality measurement with instant certificate generation and bill of lading production.
- NMi certified calculations compliant with ISO 8943, GPA 2172, ASTM 4784, and GIIGNL standards.
- Automated instrument validation using statistical process control to monitor analyzer performance and availability.
- Energy calculations with loading mass balance and billing reports for vapor returns during transfer.
- Integration with existing DCS, SCADA, and plant management systems for centralized data access.
Complete LNG Quality Release System Software Solution
The LNG QRS software eliminates manual sample handling by using online measurements from gas chromatographs and level meters to calculate quality parameters in real time. The system combines analyzer management and data acquisition (AMADAS) functionality with statistical quality calculations and outlier detection per ASTM E-178. Energy calculations follow international standards including GIIGNL, ISO 8943, and ASTM 4784, all verified and certified by NMi for regulatory compliance. This automation provides instant availability of quality certificates and bills of lading immediately after loading completion, reducing dispute risk and avoiding costly retrospective corrections. The software runs on standard flow computers and integrates seamlessly with existing terminal infrastructure.
