Issues with the feedstock for reformation pre-hydrogenation
Thread Content
I would like to ask fellow sailors: if the pre-hydrogenation feed tank does not have a nitrogen seal, will this cause gum formation in the feed? Is the main reason for the formation of gums the oxidation of olefins?
The reforming pre-hydrogenation feed tank does not have a nitrogen seal; nitrogen is an inert gas that does not cause the formation of gums in the feed. The main reason for the formation of gums is the oxidation of olefins.
I’ve never seen it; does gelatinous substance form there? Our plant’s raw material tanks operate at atmospheric pressure
Our factory controls the pressure in the raw material tanks at 0.25 MPa through high-wattage pressure supplementation and low-wattage pressure relief, and we have never encountered any gelation!
Why not use nitrogen sealing? It seems like the cost isn’t very high, right? Moreover, nitrogen sealing can also increase the head of the feed pump.
