空气顶升液化天然气储罐罐顶平衡装置设计与研究

摘要

This article presents the balance devices design, the requirements for installation as well as the control points during the process of the air - raising of the roof of the full containment Liquefied Natural Gas (LNG) Storage Tank. By taking the 50, 000m3 LNG storage tank as example, it systematically introduces the calculation of the balance devices and the operating essentials while air - raising. This balance system was applied during construction and obtained good results.%介绍了全容式液化天然气(LNG)储罐罐顶空气顶升的平衡装置设计、安装要求以及顶升过程中的控制要点,并以5×104 m3 LNG储罐为例,系统介绍了其平衡装置的计算和顶升中的操作要领.该系统在建造过程中采用,取得了良好的效果.
