METHOD OF UTILIZATION OF THE COLD OF THE LIQUID NATURAL GAS REGASIFICATION Russian patent published in 2008 - IPC F17C9/02 

FIELD: natural gas industry; methods of utilization of the cold of the liquid natural gas regasification.

SUBSTANCE: the invention is pertaining to the technology of realization of the process of the liquid natural gas regasification. The regasification of the liquid natural gas is exercised at the expense of usage in the capacity of the external heat-carrier the water, which as a result of the heat-exchange with the liquid natural gas is exposed to congealing. The liquid natural gas is fed into the first heat-exchange apparatus till congelation in it of the larger part of the water, then the liquid natural gas is fed into the second heat-exchange apparatus. After removal of the non- frozen water the formed ice is extracted from the heat-exchange apparatus or thawed and the formed water is withdrawn. Usage of the invention allows to realize the development of the commercially effective method of utilization of the cold of the regasification of the liquid natural gas at preservation of the acceptable mass-size parameters of the heat-exchange equipment.

EFFECT: the invention allows to realize the development of the commercially effective method of utilization of the cold of the regasification of the liquid natural gas.
