摘要:
LNG低温管道预冷是LNG工程投产试运行的难点，采用FLUENT软件对Φ630 × 10 mm低温管道进行BOG气体预冷工艺模拟，在0.2 m/s、0.5 m/s、1 m/s流速下，获得了BOG预冷过程的管道温度变化规律，以及低温管道在预冷过程中的实时温度显示，并制定了低温管道预冷方案。
LNG low-temperature pipe pre-cooling is difficult point of completion and commissioning of LNG project. Under the flow rate of 0.2 m/s, 0.5 m/s and 1 m/s, FLUENT software is used to conduct si-mulation of BOG gas pre-cooling technology for Φ630 × 10 mm low-temperature pipe to obtain temperature change regularity of pipe during BOG pre-cooling process and real-time display of temperature of low-temperature pipe during pre-cooling process and to formulate pre-cooling plan of low-temperature pipe.
