多气源条件下LNG接收站储存规模分析

Storage Capacity Analysis of LNG Receiving Terminal under Multiple Gas Sources Condition

基于某地区天然气供气及用气特性采用动态分析的方法分析LNG接收站储存规模、LNG接收站每月库存变化情况及趋势、上游LNG船次。调整船期,在保证下游季节调峰要求的前提下,降低LNG接收站的投资额。动态分析的方法可用于设计前期确定LNG接收站储存规模,确定经济合理的储罐数量,初步掌握均匀来船和船期调整后LNG接收站库存变化情况。

Based on the natural gas supply and consumption characteristics in an area, the storage ca- pacity of LNG receiving terminal, monthly LNG inven- tory variation and trend, and the number of upstream LNG ships are analyzed by dynamic analysis method. On the premise of ensuring the requirements of down- stream seasonal peak shaving, the investment of LNG receiving terminal is reduced by adjusting LNG ship sailing schedule. The dynamic analysis method can be used to determine the capacity of LNG receiving termi- nal in the preliminary design stage, determine the eco- nomic and reasonable number of tanks and preliminari- ly know well the inventory variation at LNG receiving terminal after uniform shipping or adjusting LNG ship sailing schedule.
