NATURAL GAS LIQUIFICATION DEVICE, AND NATURAL GAS LIQUIFICATION DEVICE DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2019/097571
Kind Code:
A1
Abstract:
[Problem] To provide a natural gas liquification device which is not easily affected by the surrounding weather and which comprises an air-cooled type heat exchanger which can stably exhibit the cooling performance of a liquid to be cooled. [Solution] A natural gas liquification device 1 liquifies natural gas and has a plurality of air-cooled type heat exchangers 2 for cooling liquid to be cooled that is handled by the natural gas liquification device 1, the heat exchangers being disposed side by side on the upper face of a frame 6. Among the plurality of air-cooled type heat exchangers 2, at least air-cooled type heat exchangers 2 which are disposed along the face where wind W blows at least toward the frame 6 include a high differential pressure type air-cooled type heat exchanger 2a which has the ability to supply a preset set flow of cooling air, at a preset set differential pressure within a range of 200 to 1000Pa for the differential pressure of the cooling air prior to and after passing through a tube bundle 230 formed by bundling tubes 23 through which the liquid to be cooled flows.
