What aspects should be primarily considered in the process design for starting up and shutting down the unit?
Thread Content
The existing designs typically use a ratio corresponding to normal operation as the operating condition during startup; they take into account the situation where there is high pressure upstream while only N2 maintains pressure downstream during startup
Valves usually need to be installed. If this situation does not last long, a regular stop valve or throttle valve can be used ； If the duration is long and there is also a certain pressure difference before and after normal operation, it is necessary to consider installing a control valve.
While driving, slowly reduce the pressure difference by adjusting the valve. I wonder if there are any other protection systems that can be added? If you know, please tell me! !
