您要查找的是不是:
- Natural gas liquification involves both mixed-refrigerant cycle and nitrogen expander cycle. 近几年国内天然气液化技术主要采用混合工质液化循环和氮膨胀液化循环。
- Whereas, the optimal heat rejection pressure in the expander cycle is different from that of in the throttle valve cycle. 但是,膨胀机循环的最佳高压压力与节流阀循环的最佳高压压力不同。
- The results show that the N2-CH4 expander cycle has advantage over the mixed-refrlgerant cycle on the premise of no propane pre-cooling. 结果表明:在没有丙烷预冷的前提下,采用N2-CH4膨胀机液化流程优于混合制冷剂液化流程;
- When the compressor and the expander efficiencies are given, the optimal heat rejection pressure in the CO2 throttle valve cycle is greater than that of in the expander cycle. 当压缩机和膨胀机的效率一定时,CO2节流阀循环的最佳高压压力比膨胀机循环的高。
- In order to calculate conveniently, the values of the optimal heat rejection pressure in the expander cycle are regressed, and a calculation correlation is obtained. 为了计算方便,对膨胀机循环的最佳高压压力进行了计算和数据回归,并给出了计算关联式。
