半冷半压式液化石油气船再液化装置研究

再液化装置是半冷半压式液化石油气船的关键设备，在保障液化石油气船运营的安全性和经济怀方面发挥着重要作用。首先对大型半冷半压式液化石油气船再液化装置适用的制冷循环类型进行了分析，然后在液化热力参数计算的基础上对低温液化流程进行了热力计算与优化，最后对再液化装置进行了有效能分析，提出了减少再液化装置有效能损失的措施。

STUDY ON RELIQUEFACTION PLANT IN LPG CARRIER

Reliquefaction plant is the key unit in LPG carrier and plays an important role in improving the safety and economy of LPG carrier.First an analysis was made on refrigerating cycles applied to reliquefaction plant,then thermodynamic analysis and optimization of liquefaction process were carried out based on the computation of thermodynamic parameters of liquid cargo,finally exergy analysis method was applied to reliquefaction plant and useful advice was proposed to reduce exergy loss.
