Title: The development of mathematical model for cool down technique in the LNG pipe-line system

Abstract

An increase in demand for LNG as energy source can be expected since LNG is clean, in stable supply and produces low levels of carbon dioxide. Expansion of various LNG plants is planned. However, the optimal design of the LNG pipe-line systems has not yet been determined since the LNG transport phenomenon is not yet fully understood clearly. For example, in the LNG pipe-line system, large temperature gradients occur when the LNG transport starts. Therefore, although the necessity to cool down the pipe in order to minimize serious deformation is clear, the studies to understand it quantitatively have not been carried out. In this study, experiments on a commercial plant scale and a computer simulation, made up of structural analysis and two phase flow simulation were carried out to establish a prediction model of pipe deformation and to understand the phenomenon in the pipe.
