LNG Liquefaction Plants


The LINEX-OL Series small scale LNG liquefaction system takes versatility to the next level. Using an open-loop design with sacrificial source of liquid nitrogen as the refrigerant, the LINEX-OL provides a clean, consistent stream of liquid natural gas. This low capital, simple-to-operate approach to liquefaction is ideally suited for pilot projects where the market is still being 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.

The LINEX-OL plant comes in two preassembled, pre-piped, pre-wired modules: the cold box and the LIN pump skid (when required).
