用蒸发气体充填LNG储罐隔热层

Study and Experiment on Replacing N₂ with BOG in the Thermocase of LNG Tank

摘要: 从普通堆积隔热型LNG储罐对隔热层充填气体的要求出发, 对BOG(蒸发气体)和N₂(氮气)的各项性质进行了分析和对比, 并在此基础上进行了试验验证, 结果表明, 用BOG替换N₂充填LNG储罐隔热层不仅在理论上、技术上可行, 而且还具有较好的经济性, 具有一定的推广应用价值。

Abstract: Accordingly to the requirements of generally accumulated heat insulation LNG tank to gas filled in thermocase, BOG and N₂ are compared and analyzed. The theoretical results show that it is feasible and eeonomical to replace N₂ with BOG in thermocase of LNG tank. On the basis of the theoretical results, experiments are made. The experimental results indicate that it is feasible to replace N₂ with BOG from the view of technology, and it has a good economical effieiency and is worthy to be popularized.
