Method for warming or evaporation of liquefied natural gas, involves warming liquefied natural gas against heating medium, and warming or evaporating partial flow of liquefied natural gas against technical gas

摘要

The method involves warming the liquefied natural gas (2,3) against a heating medium, and warming or evaporating a partial flow of the liquefied natural gas against a technical gas (8,9). The technical gas is partly liquefied. The technical gas is a gaseous nitrogen, gaseous oxygen, ammonia, propane or ethane. The technical gas is pressurized before the heat exchange with the liquefied natural gas.
