LNG Import Terminals
LNG Import Terminals
LNG (Liquefied natural gas) import terminals receive LNG from LNG carriers for storage, regasification and feed into to the local gas supply grids. Depending on the size of the tanks, the load level of the LNG, the ambient temperature and the quality of LNG tank insulation the amount of boil-off gas (BOG) per hour changes.
Typically the BOG is fed into different processes:
- Fuel gas supply for power plants
- Minimum send-out (MSO) applications (minimum agreed amount of gas continuously fed into the gas distribution grid).
Burckhardt Compression’s Laby® Compressor solution perfectly matches the requirements of these processes:
- Reciprocating compressor solutions offer the best in class gas control due to the insensitivity of this technology to dynamic suction/discharge pressure, mass flow changes and gas composition.
- The Laby® Compressor solution for LNG import terminals maximizes the operational flexibility due to the use of temperature insensitive, contactless and oil-free labyrinth sealing system on pistons and piston rods. This technology eliminates the need for gas pre-warming or compressor pre-cooling.
- Between the compressor stages, gas side streams to feed e.g. re-liquefaction, power plants or other processes allow multi-purpose compression solutions and eliminate individual compressor equipment per process.
- The Laby® Compressor solution is designed gas tight to eliminate gas loss to the flare and N2 purging.
Burckhardt Compression’s BOG handling solutions help owners to minimize operational expenses (OPEX) by eliminating major wear parts like piston rings and packings with the result of highest availability and longest mean time between overhauls (MTBO). Burckhardt Compression offers its compressor solutions as complete turn-key installations, engineered packages or bare shaft compressors. Our in-house competence includes compressor design and sizing, pulsation and vibration studies, plant engineering, instrumentation and PLC programming.
