As in the case of a Thermal Oxidiser, the exhaust
gas is raised to a temperature of 750 - 850°C and
held at temperature for a suitable residence time.
In this case, however, the hot, treated exhaust gas
goes to stack through one side of a conventional heat
exchanger, whilst the cool, untreated gas is preheated
on its way to the oxidiser through the other side of
the exchanger.

Further heat recovery systems can be added, or may even
replace the recuperator. If the site requires a large amount
of heat for other processes, for example, it may be possible
to use all of the heat generated in the oxidiser in an existing
hot oil heating system. Other possibilities include heating
air for process dryers, space heating, etc.
The main advantage of the recuperative system is its flexibility.
It can be used for large and small flow rates and for high or low
solvent concentrations. It can also be used for any solvent that
can be handled in a catalytic or regenerative oxidiser, plus many
that cannot be handled catalytically. It is also suitable for
either continuous or intermittent operation (e.g. for one 8 hour
shift per day, 5 days per week) with no significant penalty in
running cost. Unforeseen future changes in solvent type or
concentration are accommodated simply by the automatic temperature
controller.
We have a considerable reference list of recuperative thermal oxidisers,
including thirteen supplied to one customer over the past few years.
