Acetone: Hand tool cleaning tanks for -Reply



We have a great study at:
http://p2.utep.edu/casestudies/chmprf193.htm
Althought it is not mentioned, counter current rinsing was also a
big factor in reducing Acetone emisisions and use.

An employee came up with a flip top to cover the buckets of
Acetone when not in use.  It is nothing fancy, and definitely NOT
expensive.   We don't have a picture for you, but I am sure
Chem-pruf will be happy to talk with you if you call the number on
the case study.

I am working with marble casting facilities (sinks, bathtubs,
shower stalls)
that use styrene resin and limestone to manufacture their
products.  Many
have reduced acetone use except for cleaning catalyzed material
from
hand tools (metal trowels and scrapers). Many have built crude
tool
washing tanks by cutting a 55 gallon drum horizontally and
adding legs and
a top, then adding acetone. Some tops are just plywood with no
hinges.
There are no drains on these tanks and acetone is left in them
all the time
until it is removed by bailing (if there is any left).  As you can
imagine, most
acetone evaporates which creates a variety of concerns. 

Are there some good (and reasonably priced) tanks that would
work well
for acetone to minimize emissions.  A drain underneath to an
overnight tank
would be a good idea, decent fitting lid, a recirculating pump to
move the
acetone around in the tank,  and dual pans within the tank may
all be
useful.  A manufacturers name and  phone/address and/or
website would
be useful.

Also, has anyone had first hand experience with an acetone
replacement
in this marble casting industry that works well enough that you
would
recommend giving it a go?  Tool cleaning is performed inside a
building and
ventilation is usually less than desired.

Thanks for your help,
