LINEX OL – Sacrificial Nitrogen Natural Gas Liquefier

Brochures & Resources

Nikkiso Cosmodyne’s LINEX-OL series of natural gas liquefiers liquefy a clean stream of natural gas with a sacrificial source of liquid nitrogen as the refrigerant. This low capital, simple-to-operate approach to liquefaction is ideally suited for pilot projects where a market is to be tested. The plants are also well suited when the LNG capacity requirements is small, for BOG recondensing and for locations where power is not available.
