液化石油气(LPG)在天然气(LNG)时代的价值再利用

The Value Reuse of Liquefied Petroleum Gas (LPG) in the Natural Gas (LNG) Era

2010年前我国城市燃气以天然气和液化石油气(LPG)为主,2010年以后,城市燃气逐步过渡到天然气为主导气源的时代。目前,国内的天然气供应仍显不足,液化石油气依托天然气管网资源,依托较为成熟的LPG混空气工艺,依然具有再利用价值。本文首先阐述了液化石油气与天然气的组成及物理性质,然后分析了液化石油气与天然气市场应用现状,最后分别论证了液化石油气与天然气互换的技术可行性、液化石油气基础设施再利用的可行性。

Before 2010, China＇s urban gas was dominated by natural gas and liquefied petroleum gas（LPG）. After 2010, the city gas gradually transited to natural gas as the dominant gas source. At present, the domestic natural gas supply is still insufficient, liquefied petroleum gas, relying on natural gas pipeline network resources, relying on more mature LPG mixed air technology, still has the re-use value. This paper describes the composition and physical properties of liquefied petroleum gas and natural gas, and then analyzes the liquefied petroleum gas and natural gas application market, feasibility, finally demonstrates the liquefied petroleum gas and natural gas exchange technology of liquefied petroleum gas infrastructure recycling feasibility.
