Abstract: Compared with the construction of early LNG terminals, in recent years, the construction and expansion of LNG terminals has been more and more restricted by the surrounding facilities and neighboring enterprises, resulting in the continuous occurrence of limited general layout design of the plant. Some terminals have undergone major plane changes during the design, which has brought adverse effects on various disciplines and even the overall progress of the project. Through the analysis of the hazard sources and main production units of LNG terminal, this paper identifies the main external factors affecting the LNG terminal and the corresponding fire separation distance, and puts forward several key points and precautions for the design in combination with the experience in the general layout design of a LNG terminal.
