The amount of the LNG consumption has increased annually and it is expected to be over 50% of total energy after 2030. Therefore, improvement and efficient operation of LNG plant becomes more and more important. Fractionation process is one of entire LNG plant. This part separate C1, C2, C3, C4 in order. Each column's specification and product composition are required very sensitive and high quality. So it is important to observe, detect , diagnosis the LNG plant. Principal component analysis method is applied to fractionation process in LNG plant
