    Abstract:As a core equipment in the refrigeration and liquification process, cold box plays an importance role in safe and steady operation of liquefied natural gas (LNG) plant. Described is the mixed refrigerant bias flow phenomenon occurring in cold box of LNG plant during normal operation of single cycle mixed refrigeration process, analyzed is the reason of refrigerant bias flow occurring at low production load and proposed are measures and recommendations for treating the cold box refrigerant bias flow quickly and effectively and assuring proper operation of the plant, which has directive significance for commissioning and normal operation of similar LNG plants.
