BOG reliquefaction system to Recover Energy; Reduce Emission; Optimize LNG Operations

Nord Gas Solutions is the global leader in LNG boil-off gas (BOG) reliquefaction technology, delivering energy-efficient solutions that set the standard for performance and reliability. With more than 50 systems in operation worldwide, we hold the largest installed base of BOG reliquefaction plants, both onshore and aboard LNG carriers.

Our systems are engineered for efficiency, safety and flexibility, ensuring robust performance in the most demanding environments. By working closely with our customers, we create tailored solutions that enhance fuel flexibility, optimize energy use, and support environmental goals in today's rapidly evolving LNG market.

Technical Data

Controlling LNG tank pressure is essential for safe and efficient operations. Nord Gas Solutions' reliquefaction technology achieves this by converting boil-off gas (BOG) back into liquid form. At the heart of the process is a reversed nitrogen Brayton cycle - a closed-loop system that removes heat from the gas with exceptional efficiency.

Our solutions are designed to handle 100% of BOG, giving operators complete control over their LNG inventory. Every system is custom-engineered to fit the required footprint and capacity making it ideal for onshore facilities such as LNG terminals.
