摘要

液化天然气（LNG）储罐产生的蒸发气（BOG）中氦气含量较高，故可以BOG为原料提纯氦气。传统两塔-膨胀制冷提氦工艺分离效率不高，生产的氦气产品浓度有限。为此提出了三塔-氮膨胀法低温提氦工艺，并利用HYSYS软件进行了模拟和优化。结果表明，三塔-氮膨胀法低温提氦工艺在LNG液化率、氦气产品浓度和氦气回收率等指标上明显优于传统两塔-膨胀制冷提氦工艺。三塔-氮膨胀法低温提氦工艺经过进一步优化，可在总能耗少量增加的条件下，使氦气产品浓度（物质的量分数）达到95.60%，氦气回收率达到99.99%。该工艺仅采用低温精馏即得到了高回收率高浓度的氦气，综合性能优势明显。

Abstract

The boil-off gas (BOG) from liquefied natural gas (LNG) storage tanks has a high helium content

which makes it a suitable raw material for helium extraction. The traditional two tower expansion refrigeration process for helium extraction has low separation efficiency and limited helium product concentration. A three tower nitrogen expansion process for low-temperature helium extraction was proposed

and HYSYS software was used for simulation and optimization. The results show that the three tower nitrogen expansion process for low-temperature helium extraction has significant advantages in terms of LNG liquefaction rate

helium product concentration and helium recovery rate

compared to the traditional two tower expansion refrigeration process for helium extraction. After further optimization

the three tower nitrogen expansion process for low-temperature helium extraction can achieve a helium product concentration (mole fraction) of 95.60% and a helium recovery rate of 99.99% with a slight increase in total power consumption. This process obtains high-concentration helium with high recovery rate using only low-temperature distillation

and has obvious comprehensive performance advantages.
