[labnetwork] catastrophic release scrubbers

[Dennis Schweiger]

Iulian,

I figured everyone would want to see this response to your question as well.

We looked at the catastrophic release scenario when we designed the
expansion for our fab here at UofM, and by installing a restrictive flow
orifice in the cylinder (0.010"), minimizing the fill quantity (short
filling the cylinder to considerably less than a maximum), and maximizing
the dilution at the tip of the exhaust fans (using Strobic fans), we were
able to find a workable/acceptable solution.  It would take a "huge"
abatement system to handle what could essentially never happen.  It made
more sense to put our capital dollars into something that worked for
everything (the additional exhaust dilution), and share that capacity
across the entire fab.

Take care,

which group do you belong?
