Understanding of the decrease in hydrogenation capacity and the reduction in turbine speed

The processing capacity is low, requiring less recycle hydrogen and resulting in a reduced turbine speed.

Can it be understood in this way: with a lower processing volume, less heat is released during the reaction; by reducing the amount of cyclic hydrogen, less heat is carried away, thus ensuring that the reaction proceeds normally.

In other words, the processing volume is reduced, so as much cyclohydrogen is not required to maintain the hydrogen partial pressure. Are there any risks to not reducing the speed? Just wasting steam?

Can it run properly without shifting gears whether the load is light or heavy? The air volume is low and the rotation speed is high – can the inlet pressure be maintained?

Adjust the hydrogen-to-oil ratio; otherwise, power consumption will be high.

What is the relationship between the turbine speed and the hydrogen partial pressure? The flow rate exists to regulate the hydrogen-to-oil ratio.

The volume flow rate must match the work done by the compressor; the higher the speed, the lower the inlet pressure. A low inlet pressure can also cause the compressor to surge!

I’m not going to discuss this with you; turbine surge is related to the inlet flow rate. I’ve never seen anything to do with inlet pressure

Simply put, the processing capacity decreases, hydrogen consumption drops, the hydrogen partial pressure rises, and the amount of circulating hydrogen increases. To reduce the load on high-pressure air coolers and save energy in the turbine, the turbine speed is reduced to keep the amount of circulating hydrogen within a certain controlled range

Learning is an endless process… Let me take a look at your resume... Well, there are many reasons that can cause compressor surge, but basically they fall into two categories: The first category is when the operating flow rate is less than the surge flow rate, such as excessive reduction in production, insufficient intake air supply, clogged inlet filters, high pipeline resistance, or blockages in the impeller channels or airflow passages. The second case: the outlet pressure of the compressor is lower than the pipeline network pressure. Such as increased pipeline resistance, too low intake pressure, changes in compressor speed, etc. If the outlet pressure of the compressor is lower than the pressure in the pipeline network, it causes the operating point of the compressor to shift toward the low-flow region, thereby leading to a surge condition. Just search on Baidu, thank you – “reasons for compressor surging”; just search there
