PERFORMANCE TEST ON MULTILAYER THERMAL INSULATION BLANKET AND INDUSTRIAL APPLICATION TO LNG CONTAINER
摘要
High vacuum multilayer insulation material is pivotal to long-term liquid cryogenic storage. The manufacture and industrial application of multilayer insulation blanket is a development tendency for global cryogenic industry. The storage facilities for liquefied natural gas, especially the vessels used during transportation, need favorable thermal insulation performance and stability because of the burning and explosion hazards which might occur when LNG leaks. The high vacuum multilayer thermal insulation blankets were tested and applied in two LNG containers with different specifications. In addition, industrial calorimeter with new structure and large size was designed and used to test the performances. The test result of calorimeter was in line with the product performance test result, which indicated that the industrial calorimeter was more accurate than theoretical calorimeter in the measurement of material performance. It also offered more reasonable references for the application of multilayer thermal insulation blanket and the design of LNG storage equipment.
