The trade in Liquefied Natural Gas (LNG) is expanding rapidly with projects being proposed worldwide to meet the industry forecasted growth rate of 12% by the end of the decade. This paper will cover the importance of thermal efficiency in base load LNG liquefaction facilities and delineate the underlying factors as to why it is becoming more important today. Advantages of the use of aeroderivative engines include lower greenhouse gas emissions, enhanced LNG production and the ability to startup without the use of helper motors. This paper presents for the first time, a comprehensive overview of the thermal efficiency considerations for LNG liquefaction plants and the value of the use of aeroderivative engines. Part 2 of this paper covers the world’s first implementation and operational experience of aeroderivative engines in a LNG liquefaction plant.
