Analysis and design of LNG cryogenic piping, pressure vessels, and BOG compressor packages is an important business in ZCPPE. A significant difference between BOG compressors and traditional compressors used in gas gathering and transportation is the operating temperature of BOG compressor, which may be as low as about -165°C, resulting in particular issues related to material properties, pulsation analysis, piping layout and support design, and are required to be treated and resolved accordingly.
