液化天然气过冷态管输无气化距离研究

Study on No Gasification Distance of Supercooled LNG Pipeline Transportation

在液化天然气(LNG)工业强劲发展的势头下,与LNG产业链相关的输送管道研究已被广泛的学者所关注,LNG的管道输送可以继续保有LNG的优点,如节省大量的压气机输送能耗,也可在管道输送末端利用其冷能等。建立了LNG无气化输送模型,通过编制程序得出了在不同入口参数下的无气化输送距离,并采用HYSYS软件进行了管输截面参数的验证,为LNG长距离管道输送提供理论基础。

With the development of Liquefied Natural Gas （LNG） Engineering, study on LNG pipeline transportation has become a hot spot. LNG pipeline can remain the advantages of LNG, such as saving energy and using its cold energy in the terminal of transportation. In this paper, no gasification model of LNG transportation was established, the no gasification distance under different entrance parameters was obtained, and the pipeline parameters were verified by HYSYS software, which could orovide a theoretical basis for LNG long distance pipeline transportation.
