Greetings all
I have a small stream intermittent stream of water that contains 13 wt% isopropanol. I would like to remove the isopropanol down to about 2% so the flash point is high enough to go to a POTW.
The water stream is generated in 100 gallon batches about 4 times a day.
The water is at room temperature.
I don't have a lot of room to dedicate to the isopropanol removal.
What unit operation do you think is the best way to handle this stream?
I was thinking that air stripping is a good choice.
Distilling it is possible in a single stage flash but I end up with about a 50% IPA solution that I have no use for.
Other ideas?
Thanks
Brad
