Status of the anti-surge valve when the recycle hydrogen compressor in the hydrogenation unit is started up
Thread Content
Should the anti-surge valve of the recycle hydrogen compressor in the hydrogenation unit be set to automatic or manual mode when it is started up? What is the impact on the unit when the anti-surge valve closes automatically once automatic startup exceeds the critical value? Is it necessary to manually set a certain valve position for the anti-surge valve when starting up beyond the critical point?
A fully open anti-surge valve is generally a requirement for starting; it must definitely be opened manually. After starting the turbine, gradually reduce its speed until it is shut down completely; once it is running normally, automatic mode can be activated
