A check valve is installed at the inlet of the hydrogenation reactor for analysis purposes
Thread Content
I would like to ask everyone: what are the risks of installing a check valve at the inlet of the hydrogenation reactor for the feedstock? It seems that check valves are not installed at the inlets of reactors for most feedstocks
It’s the exact opposite of what I’ve experienced; in the several reactors I’ve worked with, there are check valves at the material inlet
Is it a hydrogenation system? Basically, none are installed at the inlet to the reactor where the feedstock enters
Well*, generally, check valves are installed at the hydrogen mixing point.
Yes, both fixed-bed and slurry-bed types are available
From a safety perspective, it is necessary to prevent backflow after an abnormal shutdown of the feed pump, which could cause overpressure in the buffer tank. Isn’t the Jiujiang accident exactly like that?
Why design it? What is the reason for the design? Personally, I think it makes no difference whether there is a design or not
This is placed to prevent oil and gas from intermingling; it’s not necessary at the reactor inlet
This isn’t necessary, right? Generally, check valves are installed at the hydrogen mixing line and at the outlet of the feed pump, while check valves are placed at the reactor inlet; excessive temperature increases the risk of leakage as well as the investment costs
Is there no emergency shut-off valve at the outlet of the reaction feed pump? No interlock?
