COMの管路輸送における冷却凝固後の再起動時間実用計算法

概要

For transportation through a pipeline, COM should be kept at a temperature of 70℃, because its viscosity increases with a decrease in temperature to render its pipeline transportation difficult. This paper reviews a concept with which the authors developed a method of calculation to determine changes in temperature, viscosity, and flow velocity of COM in a pipe that take place with time, when operation of the transfer pump and transportation pipe heating system stops suddenly due to power failure and when this is reversed with the return of electric power. As COM has non-Newtonian properties, the viscosity of which changes with changes in temperature and shear rate, the authors employd new devices for the calculation method.
