Oil present at the inlet of the reforming cycle hydrogen compressor
Thread Content
The inlet of the reforming cycle hydrogen compressor is contaminated with oil, and in large quantities. Let’s discuss the possible reasons for this phenomenon. Thank you all.
The liquid separation effect of the inlet liquid separation tank is poor.
Well, it’s possible; we’ve analyzed it ourselves and found that the demisting screen in the inlet separation tank is damaged. But it’s not possible to conduct normal inspections at the moment. Are there any other reasons for this phenomenon?
Are you reciprocating machines? Was there any recontact? Is the raw material relatively light? Was too much C5 generated?
There is re-contact, but I’m not referring to reciprocating machines; of course, the inlet tanks and pipelines of reciprocating machines also contain light oil. I’m talking about turbines, that is, introducing oil at the inlet of the cycle hydrogen compressor where hydrogen is mixed with the feedstock. What you’re saying is also possible, but judging from the temperature drop in the reaction, there should be little change; moreover, the feed range hasn’t changed much, nor has the composition of the feed. If it’s you who says so, how would you handle the situation? Please clarify~
1. The load has increased. 2. Check if there is any change in the reaction, that is, more cracking occurs. 3. The cooling effect is poor; the components have not cooled down completely. 4. The foam breaker screen is damaged. Personal opinion, for reference only ； If there are any errors, please point them out.
I’ve never encountered this situation before; generally, the standard approach is to shut down the machine to deal with it. Should I wait and see instead?
The load is currently 77%, so it’s not high and there’s no change. The cracking reaction should not have increased, as hydrogen production remains unchanged and the overall temperature drop is also unchanged; since I am in the north where it is currently cold, the temperature before the liquid separation tank is still quite low. The only thing that cannot be verified right now is the demisting screen in the inlet liquid separation tank. Thank you for your suggestion
It hasn’t stopped yet; it’s a combined unit, so it’s not done yet.
Generally, as long as it can keep running, it will continue to do so. So how do you handle it now? Strengthen the drainage of the liquid separation tank? What should be done then?
Also, has the liquid level of the liquid separation tank been checked?
