Abstract
Domestic LNG receiving terminal lack of cooling speed control experience. In order to prevent damage caused by cryogenic LNG suddenly flowing into unloading pipeline,verification of the effect of the pre-cooling operation procedure must be carried out before pre-cooling operation. A computational fluid dynamics (CFD) based analysis method is proposed in this paper. A 3D CFD model is built based on a domestic LNG receiving terminal project pre-cooling procedure,and dynamic simulation is carried out for checking the pre-cooling process. The cooling rate of LNG unloading pipe can be maintained within 10℃/h,and meet the pre-cooling safety requirement. The CFD calculation results are compared with actual measurements on site. The accuracy of numerical simulation for pre-cooling could be within 7% of test data. which proves that CFD calculation method can be used in confirming the rationality of LNG receiving terminal's pre-cooling procedure and checking calculation.关键词
