    초록·키워드

    Liquefied natural gas or LNG is natural gas that has been converted to liquid form for ease of storage or transport. Liquefied natural gas takes up about 1/600th the volume of natural gas at a stove burner tip. In this paper, we will list the properties of LNG at the scope of pressure and temperature from 80 bar to 130 bar, 108.15 K to 328.15 K using software Nist Supertrapp. Main properties are density, heat capacity, entropy, conductivity, enthalpy, viscosity, which are highly depended on pressure and temperature. In this paper we use two softwares to calculate the above properties, Nist Supertrapp and Hysys. To compare the difference between varies product regions, we choose Alaska, Alaska Brunei abdai Indonesia Malaysia Oman Karta, except Alaska other regions LNG have slightly different percentage of component. After presenting calculation result of Alaska LNG from software Nist Supertrapp, some difference between two softwares result will also be listed in figures.
