摘要：
With the continuous increase of China's imported LNG, some large-scale LNG receiving terminals in China have begun to be expanded to improve their gasification and transportation capacity. The technical problems arising from parallel operation of multiple high-pressure pumps were sorted out based on the data of four years' successful operation of the phase II project of the PetroChina Tangshan LNG receiving terminal. The causes of these problems were analyzed according to design data, pipeline layout and interlock protection logic, and the main factors influencing the flow rate distribution between multiple high-pressure pumps were determined. The measures for optimizing and improving the related operation modes and technological process were proposed.
