【摘要】：双混合制冷剂液化工艺(DMR)在海上FLNG应用时受到波浪晃荡的影响,分离器会出现分离不完全和换热器会存在换热不充分的现象,从而影响液化工艺的性能指标。通过建立DMR静态仿真模型,对分离器气相中重组分含量进行了敏感性分析,结果表明分离器气相中重组分含量的增加会降低DMR液化能力;在静态仿真模型的基础上,建立DMR动态仿真模型,针对我国近海海况进行了晃荡条件下分离器和换热器扰动敏感性分析,结果表明,分离器和换热器在晃荡条件下均会使DMR液化能力有所下降,但下降程度不足2%,说明DMR具有较好的海上适应性。本文研究成果可以为FLNG液化工艺、设备等方面提供理论基础,具有较强的理论和工程意义。
[Abstract]:Double-mixed refrigerant liquefaction process is affected by wave sloshing in offshore FLNG application, the separation of the separator will be incomplete and the heat transfer will not be sufficient in the heat exchanger. By establishing the static simulation model of DMR, the sensitivity of the recombination content in the gas phase of the separator was analyzed. The results show that the increase of the recombination fraction content in the gas phase of the separator will reduce the liquefaction ability of DMR. Based on the static simulation model, the DMR dynamic simulation model is established, and the sensitivity analysis of the separator and heat exchanger disturbance under the condition of sloshing is carried out. The results show that. Both the separator and the heat exchanger can reduce the liquefaction capacity of DMR under sloshing condition, but the degree of decrease is less than 2%. The results of this paper can provide a theoretical basis for the liquefaction process and equipment of FLNG, and have a strong theoretical and engineering significance.
