oxygen and combustible material do not go well together for safety.

Especially hydrocarbon fractions heated to ~300F or ~400F. Mother of All Bombs. I believe it's the primary reason why they use a nitrogen purge, and why the oxygen sensors (65 of them?) are so critical.

It's another reason why you don't want some minimum wage fork lift driver monitoring the process.

Agreed but their process is somewhat different and naturally takes care of this. I think because heat is not applied (catalyst instead) Weird but true. One of the longs would know. What you are saying about oxygen is totally true.

You are confusing the heating/stack part with the internal operation of the machine. They are 2 totally different things. The internal process is anaerobic.......we're discussing the stack...not the process itself.........z

I have been wondering about the oxygen issue myself. If oxygen is in the system, this could be a potential explosion hazard. However, the company has ran the machine without incident.

Thus, it remains a little puzzling to me because oxygen and combustible material do not go well together for safety.


Oxygen compounds are found in crude. They do not pose an explosion hazard in a refining process.
