Key Technology and Application Research of Cryogenic Insulation for LNG Plant Under Polar Climate

Peigang Xin, Yanfang Zhang, Jian Tang, Fengyan Yang, and Haijun Yang
Abstract—Cellular glass is applied as cryogenic insulation material in central process module of YAMAL LNG Plant. Characteristics of cellular glass such as hard, fragile and so on, bring much difficulty to prefabrication and installation and easily leave quality risk. Based on the actual cryogenic insulation design and installation for YAMAL LNG Plant, this paper analyzes and researches insulation procedures for special-shaped pieces such as tee, elbow, valves where insulation quality problem easily takes place, finally to realize innovation in design and ensure the construction quality. These procedures and installation methods mentioned in this paper are based on the polar climate environment. Meanwhile, the rigorous design and perfect application effect fully meet the requirements of the cryogenic technology so that normal operation of liquefied natural gas processing plant can be effectively guaranteed.

Index Terms—LNG, cryogenic insulation, cellular glass.
