LINEX-BOG – Boil-Off Gas Liquefiers/Subcoolers

 

about-engineering_03Cosmodyne’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.

 

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.

LINEX-BOG – Boil-Off Gas Liquefiers/Subcoolers

 

The LINEX line of liquefiers incorporate Cosmodyne’s nearly 50 years of experience in cryogenic design. The liquefier is based on a closed-loop nitrogen expansion cycle and comes shipped in the following distinct, pre-piped, pre-wired modules:

– nitrogen refrigeration skid with cold box and expander
– nitrogen recycle compressor with motor and cooler(s)

System requires a simple foundation, supply of low voltage power and cooling power.
