WebNikkiso 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.
