Question

explain storage of H2 O2

Answer 1

H2O2 are light ,shock sensitive.

Hence they are stored in Urea.

Answer 2

Hydrogen peroxide can be delivered in small packs, in intermediate bulk containers (IBCs) or in bulk quantities by rail, road tankers, or in ISO tank containers.
Small containers and IBCs should be stored unopened, in an upright position
and taking account of good warehousing practice with respect to stacking
height. The breather vents must not be blocked. Storage should be such that
faulty containers can be easily detected and removed. They must never be role
or laid on their side. They may be stored in a building with a concrete floor
slightly inclined towards drainage and designed in the form of a shallow sump
about 10 cm deep and with a small driver on ramp to the threshold. The storage
area should normally be unheated and adequate ventilation ensured. Although
heat sources are to be avoided, in certain circumstances such as extreme
climatic conditions, heating may be required, but H2O2 containers must not be
placed unduly close to sources of heat. Containers may be stored outside,
preferably protected from direct sunlight. A canopy may be required in hot,
sunny climates. The storage area must be kept clean and free from combustible
materials and other incompatible chemicals. A water hose should be available
for flushing away spillages and leaks to a safe place. A safety shower and an
eye bath should be provided for treatment of personnel who come into bodily
contact with hydrogen peroxide. Pipelines, especially those carrying chemicals,
must not pass through the storage area.
Returnable empty containers should be kept closed and clean and returned to
the storage area as soon as possible. They should not be washed out except
with non contaminated water.

In addition to local regulations for storage on site, SOLVAY INTERIOR recommends
a contained concrete area with drain. The storage area, preferably outdoors,
must generally conform to agreed standards of accessibility and cleanliness.
Particular care should be taken to ensure that the ISO tank cannot be damaged
by passing vehicles.
Care must also be taken to ensure that the manhole is kept closed, to avoid
sources of contamination. The breather vent must not be blocked or obstructed, otherwise over pressurisation can occur.
ISO tanks must never be washed out or used for the storage of other materials
or for any other purpose.
With an annual usage requirement of, say, 50 tonnes or more of hydrogen Peri
d e solution, it may become economical to construct a bulk storage unit.
H2O2
storage tanks comprise numerous specific design features and fittings.
Similarly, associated pipework, pumps, ancillary equipment and instruments
are highly specific to H2O2
.
Other important considerations are the layout and installation, which require
expert advice. Factors such as statutory requirements, tank location, correct
materials of construction, and preconditioning of equipment to receive hydro g e n
peroxide are also important.
