Description

Technical Field

[0002] Marine transportation is the main way of global LNG trade. During the transportation process of LNG ships, part of the LNG will inevitably evaporate into BOG flash gas. Direct emission will cause economic losses and greenhouse hazards. Using an LNG cryogenic device to liquefy it is the main BOG treatment method for large LNG carriers. Compared with technical routes such as mixed refrigeration and nitrogen expansion, the cryogenic re-liquefaction technology has outstanding advantages such as a compact system, high efficiency, high reliability, and low maintenance costs. Therefore, the LNG cryogenic device is an indispensable high-value-added core equipment. At present, the global LNG cryogenic device market is basically occupied by foreign manufacturers such as Air Liquide and Cryostar. Among them, the high-power and high-efficiency magnetic levitation compression-expansion integrated machine is one of the core components of the cryogenic device, becoming a real "bottleneck" key technology that urgently needs to be solved by domestic substitution. Due to the high-power magnetic levitation compression and expansion integrated machine needing to meet requirements such as high power, high speed, explosion protection, and sealing, the volume and weight of the machine body and core components are relatively large, and it is impossible to directly turn over the machine body manually.
