本文建立了透平膨胀致冷天然气分离装置的多能复杂系统(火用)分析模型,采用过程(火用)分析法进行能量分析,找出了最大(火用)损环节,展示了系统(火用)损率的分布,对装置的热力学完善性作了概括性评价,可供该类设备的节能技术改造作参考。
In this paper, a multi-energy complex system (Exergy) analytical model of turbine expansion refrigeration natural gas separation unit was established. The energy analysis of the exergy analysis was used to find the maximum (exergy) loss link. The system ( Exergy) loss rate distribution of the thermodynamic integrity of the device made a general assessment for the energy-saving equipment of this type of technology for reference.
