摘　　要：我国从国外引进的天然气的热值高于我国管输天然气热值,因此,要对LNG(液化天然气)接收站输出的燃气进行热值调整,使引进的LNG再气化后的天然气热值与国产气热值相当。分析了LNG气化后的天然气热值调整技术,即注入空气法、注入氮气法和重烃脱离法,对各种技术的工艺原理、工艺方法,结合各种方法的优缺点进行了阐述,并进行了经济比选。The heat value of the imported natural gas was higher than that of domestic gas,therefore it was necessary to adjust the heat value of natural gas from the LNG receiving stations to make the heat value of the gasified imported LNG equivalent to that of domestic gas.The heat value adjustment technologies were analyzed,namely air injection method,nitrogen injection method,and heavy hydrocarbon removal method.The principles and processes of three methods,their advantages and disadvantages were described,economic comparison was also analyzed.
