s. A. A pressão de operaçãoo do tanque que液罐的操作压力一般低于55巴，为什么设计压力要留有一定的余量？

Se a temperatura de fr nâo低温过高，高压气中带液严重，循环氢压缩机的入口分液罐会增高甚至高报，会直接影响循环氢机如果循环氢机不会受到气体带液的影响，那么完全可以取消循环氢压缩机入口分液罐，在循环氢机的高转速下，气体带液严重会严重损坏设备氢气系统设备在损坏泄露的情况下会造成什么后果不言而喻

Portanto, 操作温度一般低于55 而设计温度一般留有一定的余量且会考虑工艺的各种工况

有安全裕量有非正常工况，例如高压空冷故障导致反应油气换热失衡，温度都有导致后路介质温度上升的趋势。设计温度高于正常操作温度并不意味允许正常操作温度可以接近设计温度。设计温度是对硬件的保护而非工艺的需求

Isto é a teoria do máximo risco prático que o processo pode suport在非正常工作状态下理论上可以承受的最高工艺警戒值/危险值。

A temperatura de projeto é1155℃已经考虑了近、防喘振等你就明白了

氢气下游有没有回到分液罐？回流旁路有冷却器吗？

应该考虑的是满负荷运行然后卸载工况下防喘振全会回到入口温度会高于55度
