LNG接收站的功能是接收、储存和气化LNG,并通过管网向下游用户供气。由于在卸船时LNG进人储罐导致罐内LNG体积变化会产生大量的蒸发气(BOG)。为了维持储罐压力的稳定,必须处理掉过量的BOG。本文以某LNG项目为例,探讨BOG压缩机处理能力的计算方法以及选型。
The function of the LNG receiving station is to receive, store and gasify the LNG and supply downstream users through the network. Due to LNG entering the storage tank during unloading, a large amount of boil-off gas (BOG) will be generated due to the change of LNG volume in the tank. In order to maintain the stability of the pressure in the tank, excess BOG must be disposed of. In this paper, an LNG project, for example, to explore BOG compressor processing capacity of the calculation methods and selection.
