LNG接收站BOG压缩机：往复式与离心式比较

BOG Compressor Used in LNG Receiving Terminals:Contrast between Reciprocating Type and Centrifugal Type

BOG压缩机作为LNG接收站的关键设备,其超低温介质对材料要求严苛,业主对于经济性、交货期、维修的要求,是选商时考虑的因素。随着低温压缩机技术的发展,往复式和离心式BOG压缩机均有应用,二者因型式不同各具特点。

BOG compressor is key equipment of LNG receiving terminal. Cryogenic temperature of its medium is stringent for material,and the owner to the requirement of economy,delivery term,and maintenance,shall be considered as factors in choosing suppliers. With the development of cryogenic compressors,both of reciprocating BOG compressors and centrifugal ones have been applied,but the characteristics vary from type.
