Towards the end of work today, it was reported that the feed pump had run dry, which also caused the PSA outlet pressure to rise

Can someone explain to me, huh? How is there a connection between these two? Is it a problem with the recycled hydrogen?
The hydrogenation reaction feed pump becomes evacuated, resulting in a reduced flow rate; this causes the system pressure to rise. Hydrogen is directed to the hydrogen buffer tank as a result, which also leads to an increase in pressure, and consequently an increase in the PSA outlet pressure!

The system’s hydrogen consumption decreases, and fresh hydrogen is continuously supplied to the hydrogenation system, which leads to an increase in the pressure at the inlet of the recycle hydrogen compressor. As a result, the pressures at the inlet and outlet of the fresh hydrogen compressor rise, and the pressure buildup in the PSA unit causes the outlet pressure to increase as well.
You don’t need hydrogen; it’s only natural that the PSA level doesn’t drop and there’s no pressure buildup.
