alloy catalyst gauzes lose weight during the combustion process
: they suffer a form of wear. Valuable precious metals are
lost through the gas-phase reactions, representing a not inconsiderable
financial burden for the customer.
Heraeus therefore offers systems which work on palladium basis
and which permit the recovery of these precious metals. The
catchment system consists of a series of individual gauzes
which have to be specially selected according to weight, wire
diameter, and mesh count. The sequence of these specially
selected individual gauzes plays a decisive role. The recovery
rate depend strongly on the individual process parameters
of the various oxidation plants.It is necessary to put together
a specially designed gauze pack for each individual plant.
Heraeus is able to offer, for any plant, a specially designed
gauze pack which guarantees an optimum recovery rate and thus
the most economic solution for the customer. If knitted gauzes
are to be used for the same period of time as woven gauzes,
they will lose less platinum. Thus, the catchment pack can
be reduced in weight without impairing the recovery efficiency.
The catchment systems as well as all kind of catalyst gauzes
are refined by Ravindra Heraeus. The precious metal extracted
in this process can be reused for new gauzes.
