车载LNG储罐BOG回收研究

Study on the Recovery Plan of BOG in the Process of Using Vehicle Mounted LNG Tank

本文提出了在液化天然气客车上增设BOG储罐以回收利用蒸发损失的方案。通过计算百分百回收BOG时的理想蒸发率值可以知道,现有蒸发率仍有较大改善空间;通过维持时间的计算发现,由于新增的储罐对整车的维持时间增加少于一天,BOG回收效果并不显著,未来提高保温性降低蒸发损失或采用ANG吸附回收,是更有价值的研究方向。

In this paper,a plan is put forward to add BOG storage tanks on LNG buses to recover evaporative losses.By calculating the ideal evaporation rate value of 100%recovery BOG,it can be known that there is still room for large improvement of the existing evaporation rate,and the calculation of maintenance time is found that since the new storage tank to the vehicle maintenance time increased by less than one day,BOG recovery effect is not significant,the future increase in insulation to reduce evaporation loss or the use of ANG adsorption recovery,is a more valuable research direction.
