Sorry to disappoint you, but you’re not going to find one here.
I agree with both of your points, and would like to expand upon one...
>>For sure it would be preferable to 02 clean the tank, but the reality
>>is that you could still PP blend a tank that has been exposed to
>>hydrocarbonated air…
It’s all in the comfort level. I make my cylinders and valves ready for oxygen service and make every attempt to keep them that way to assure the second leg of the combustion triangle (fuel) is as short as possible. I spike my cylinders at home, so I can dribble the O2 in very slowly to keep the heat leg as short as possible too. Unlike a shop, I have all the time in the world and can watch “Shark Misinformation & Harassment Week” on the Discovery channel while my cylinder takes a half an hour to come up to the required pressure. If I poured half and inch of motor oil in the bottom of a cylinder and asked you to dump 1100 psi of O2 on top of it, I’d assume that that would be out of your comfort range. :-)
So again, it’s a matter of degree and a matter of comfort.
I think we’re in “violent agreement” :-)
