Acid Tanks

Poly Acid tanks are found in just about every plant that
utilizes acid in thier operations. That being said,
there are a great many types of acid and each one has
special needs for safe storage. We make and outfit
acid storage tanks for most of the acids in use.
Selecting the proper tank for acid storage involves deciding
which kind of plastic is the best suited. The proper
storage tank also needs to be rated to the correct specific
gravity rating. Deciding on the right material for
fittings and gaskets is also important. We can help
you simplify the process in making the right selections for
your acid storage tanks.
Specific Gravity Ratings:
Plastic tanks are rated according to the specific gravity of
the liquid they are designed to hold. If you want a
little more information about specific gravity,
click here. The most common specific gravity
ratings for plastic tanks are 1.9, 1.5 and 'Water Only'.
Some manufacturers use slightly different numbers. It
is important to match your liquid with a tank that is rated
for the correct specific gravity. |

 Sulfuric Acid Tanks:
Sulfuric acid is the most used
kind of acid in plants and manufacturing facilities.
It is also one of the most aggressive and dangerous acids
when stored in high concentrations. The level of
concentration of Sulfuric acid in the stored solution has a
big impact on the compatibility of tank and fitting
materials.
Two factors that affect the proper
storage of Sulfuric Acid are the density of the acid and the
fact that when water is introduced to Sulfuric Acid an
exothermic reaction takes place that gives of enough heat to
make a tank or fitting fail. Tanks need to be rated to
a high enough specific gravity for the acid concentration.
Poly tanks should also never be used for mixing sulfuric
acid and water.
Secondary containment is
especially important when storing Sulfuric acid.
Consider a double wall acid tank as an efficient storage and
containment solution.

Hydrochloric Acid Tanks:
Hydrochloric acid is a very strong, very corrosive acid that
is clear and colorless. It is formed when hydrogen
chloride dissolves in water. Hydrochloric acid
is used to make fertilizers, and dyes. It is important
in electroplating, and necessary in the photographic,
textile, and rubber industries.
All body tissues
can be negatively affected by coming in contact with
Hydrochloric acid and/or its fumes. Proper venting of
Hydrochloric acid fumes through a scrubber can be an
important aspect of proper storage.

Nitric Acid Tanks:
Nitric Acid is without color or, a yellow, or red, fuming
liquid. It emits a dangerous, acrid, suffocating odor.
Similar to Sulfuric acid, Nitric acid has an exothermic
reaction when it comes in contact with water. It will
emit heat that may damage a storage tank.
