Liquid Natural Gas Vaporization

摘要

A process for the vaporization of a cryogenic liquid is disclosed. The process may include: combusting a fuel in a burner to produce an exhaust gas; admixing ambient air and the exhaust gas to produce a mixed gas; contacting the mixed gas via indirect heat exchange with a cryogenic liquid to vaporize the cryogenic liquid. Also disclosed is a system for vaporization of a cryogenic liquid. The system may include: one or more burners for combusting a fuel to produce an exhaust gas; one or more inlets for admixing ambient air with the exhaust gas to produce a mixed gas; and one or more heat transfer conduits for indirectly heating a fluid with the mixed gas.

主权项

1. A system for vaporization of a cryogenic liquid, the system comprising:
one or more burners for combusting a fuel to produce an exhaust gas; one or more inlets for admixing, within an enclosure, the exhaust gas with ambient air to produce a mixed gas flowing longitudinally from an upstream end of the enclosure to a downstream end of the enclosure; a plurality of heat transfer conduits within the enclosure, the plurality of heat transfer conduits containing liquid natural gas and providing heat exchange within the enclosure between the mixed gas and the liquid natural gas; an outlet disposed intermediate an upstream heat transfer conduit and a first downstream heat transfer conduit to remove a part of the mixed gas from the enclosure, the part of the mixed gas defining a bypass flow of the mixed gas; and a vapor distributor to distribute the bypass flow of the mixed gas downstream of the first downstream heat transfer conduit.
