Hi all:
I'm working on a refinery unit that has a vessel at Deck 12 that'll need to have its dry adsorbent pellets removed once or twice per year as it is spent. This is a new feature on this type of unit, so we don't have specific operating experience.
As we can't be assured the material...
I have a number of pressure and level connections on a vessel that has a lot of particles and gaseous products that could condense at low temperatures into a gummy mess (technical term)
We therefore purge the taps to keep a little reverse flow on the taps to keep them from being plugged. No...
