PROBLEM TO BE SOLVED: To provide refrigerant pre-cooling systems used as part of a liquefaction processes.SOLUTION: The invention provides a system and method for liquefaction of a natural gas stream utilizing a plurality of asymmetric parallel pre-cooling circuits. The use of asymmetric parallel cooling circuits allows greater control over each refrigerant stream during a cooling process and simplifies process control by dedicating heat exchangers to performing similar duties.SELECTED DRAWING: None 【課題】液化工程の一部として使用される冷媒予冷却システムを提供する。【解決手段】複数の非対称の並列予冷却回路を使用する天然ガス流の液化のためのシステムおよび方法。非対称の並列冷却回路の使用により冷却工程中の各冷媒流のより大きな制御が可能となり、熱交換器に同様の役割を果たすことに寄与させることにより工程制御が簡素化する。【選択図】なし
