Abstract: This paper introduces the importance of process treatment facility in LNG terminal. The key equipments in BOG re-condensation process and the principles and precautions of plot plan of process treatment facilities are introduced. This article briefly describes the general principles of pipe rack piping layout, and focuses on the particularity of low-temperature piping from the aspects of π type compensator layout, limited support setting, thermal bowing effect, water hammer load and so on. During the selection of piping material, piping layout, stress analysis and construction inspection, the impact of low-temperature medium design conditions on the whole piping design shall be fully considered to ensure the quality and safety of engineering design. This paper introduces the piping layout of thermal safety valve and the setting of piping reserved interface, and puts forward some precautions for piping design conditions dilivery to civil.
