LINEX BOG – Land and Marine Based Boil Off Gas Liquefiers/Subcooler

Brochures & Resources

Nikkiso Cosmodyne’s shipboard ready and land-based systems automatically control boil-off gas generated from any storage tank containing LNG or other cryogenic liquids. The system works with tanks in most applications including pressurized tanks or those operated at atmospheric pressures.

Nikkiso Cosmodyne offers two boil-off gas options that utilize a simple nitrogen based refrigeration cycle. The first option sub-cools a stream of LNG that is passed through a client’s spray header to collapse pressure. The second option re-liquefies the boil-off gas and the resulting LNG stream returns to the client’s tank.
