LNG
LNG production and regasification involve extreme temperature shifts, high-pressure processes, and the need for maximum thermal efficiency. Whether in liquefaction terminals or downstream re-gas units, maintaining system integrity and energy recovery under cryogenic conditions is critical.

The main challenges in this sector
The main challenges in this sector
Cryogenic operating temperatures
Liquefying natural gas requires cooling it to around -160°C. All equipment must maintain performance and structural integrity at these extreme cryogenic conditions.
High-pressure processes
Compression and gas transport operate under high pressures, requiring thermal systems that can withstand mechanical stress without leaking or degrading.
Energy-intensive liquefaction cycles
The refrigeration and heat recovery steps consume significant energy. Optimized heat exchange is essential to improve energy efficiency and reduce emissions.
Safety and environmental demands
Any leakage or inefficiency in LNG systems can lead to gas loss or hazards, making robust, sealed, and high-performance exchangers indispensable.
Our involvement in the sector
Nexson provides cryogenically capable, leak-free thermal solutions tailored to the extreme demands of LNG liquefaction and regasification facilities.
Maximizing thermal performance in cryogenic LNG environments
Welded construction for absolute tightness
The Nexson PCHE features a fully welded, diffusion-bonded design that ensures complete gas tightness. With no gaskets or seals, the risk of leakage is eliminated even under high pressure or during rapid thermal transitions.
Cryogenic performance and high-pressure resistance
Built from stainless steels and nickel-based alloys, the PCHE retains its mechanical integrity and thermal performance at cryogenic temperatures below -160°C. It is engineered to withstand the high pressures typical of LNG processes without compromising safety or efficiency.
Efficient integration in liquefaction and regasification cycles
The PCHE is used in key stages of LNG processes, including subcooling, condensation, and intermediate heating. Its high heat transfer surface area and compact structure support optimized energy recovery and contribute to improved cycle performance.
Compact, robust design for demanding environments
Nexson solutions are suited for both offshore and onshore LNG installations, including FPSOs, FLNG units, and coastal terminals. The compact geometry of the PCHE allows for easy integration, while its solid-state construction offers long-term resistance to corrosion, vibration, and thermal cycling.
