Limits on hydrogen content in hydrogen production feedstocks
Thread Content
What are the requirements regarding the hydrogen content in the hydrogen production feedstock, especially the upper limit? If the proportion of hydrogen in the feed gas is too high, exceeding 50% by volume, could this have an impact on the hydrogenation catalysts inside the hydrogenation reactor?
If that’s the case, then there’s no need to add hydrogen
After consuming some of the low-grade gas, should it all be sent to the torch? It’s a pity to do that, but the hydrogen content is too high, resulting in less hydrogen production
Yes, it seems too high; could it have an impact on the hydrogenation catalyst?
It’s fine; there’s no need to add hydrogen. A low-level hydrogen sulfide concentration of just a few dozen ppm is sufficient
