摘　　要：随着液化天然气(LNG)产业的兴起,天然气在我国能源结构中占有越来越重要的位置,对于天然气液化流程、LNG储存运输以及气化流程模拟的要求越来越高,天然气热物性质计算的精度在流程模拟中至关重要。采用P-R方程计算了密度和粘度的精度,为天然气的流程模拟提供进一步的理论基础。With the development of new energy liquefied natural gas （LNG） industry, natural gas plays more and more important role in energy structure in China. High accuracy simulation of process flow, such as natural gas liquefaction, LNG storage and transportation, LNG gasification, is required. The accuracy of natural gas thermodynamic properties calculation is an important part of process flow simulation. It is necessary to prove its accuracy in order to provide theoretical foundations for process flow simulation. In this article, density and viscosity were calculated by P-R state equation, which can provide a theoretical basis for LNG process flow simulation.
