Release of Chlorine form 1 ton container(s) 1

[5wp]

I'm looking for a video that show what it looks like when a valve is not functional(broken) and the tonner is allowed to totally evacuate. I've seen a video clip a number of years ago but I'm not able to relocate a copy.
Secondly, has anyone calulated how long it would take for a tonner to empty considering it is at 500kpa to start with and a valve is opened wide open?
Could it empty in 15 minutes?
Thanks 5wp

i am not aware of the video . . . good luck with the video.

as far as the calc, i have not. Surely you have the knowledge and skills to conduct an analysis yourself.

I guess I should go through it, just thought that someone may have already done it. Thanks anyway.

You might try this company. That is what they sell against:

I've seen a similar video, and I think our chlorine vendor had a copy. It's been several years, so my memory is a bit fuzzy.

You might try

http://www.chlorineinstitute.org/

as a starting point.

Good Luck.

I've just finished talking to a rep from the Chlorine Institute, but no luck.
Thanks anyway

Your question about whether or not a ton chlorine cylinder could empty in 15 minutes (if there was a broken valve) depends upon how accurate you want the answer to be. If you want an absolutely exact answer, that would involve a very great deal of work and time.

If you would be satisfied with an answer that is perhaps within plus or minus 15%, then:

1-- Go to this website:

http://www.air-dispersion.com/source.html

2-- Select either metric units or USA units. Then select "Gas Discharge From Pressure Source"
3-- There you will find the equation for calculating the choked flow rate (mass per second) for the accidental discharge of a pressurized gas. That will be the instantaneous initial flow rate.
4-- The final flow rate as the cylinder empties will be zero. Thus, the average flow rate (mass per second) will be the initial flow rate divided by two. This assumes that the flow rate will linear as the cylinder empties ... which is not true. Therefore, the answer may have an error of about 15%.

Thanks Mbeychok.
I'll pursue this web site and do some number crunching.

Hadn't thought about it...is the chlorine in the cylinder gas or liquid?

The Chlorine is liquid but is drawn off as gas in this case. The application
is in a water plant.
