Chemical Engineering June 2018 - 58

have opened new or alternative pathways for
the synthesis of new compounds and materials
and their production on an industrial scale.
New concepts of stirred-tank photochemical
reactors, of the well fixation, as well as of new
material combinations provide for their use in
particular for processes starting in, or resulting
in, a heterogeneous phase. The stirredtank
reactor, with its robust and flexible operation
characteristics, also allows for batch,
fed-batch and continuous operation.
Modern tools, such as numerical flow simulations
(CFD), optimize the mixing process for
multi-phase fluids, and finite element analysis
(FEA) provides a reliable and economic design,
even for critical materials, such as glass and
highly corrosion-resistant alloys. Apart from
new reactor designs, photochemical technology
has made fast and profound progress in
the domains of radiation sources and in situ
photometric analysis. On a production scale,
operational safety aspects - techniques of
lamp fixation and sealing, electrical power
control, monitoring of the process media and
explosion-proof design - withstand any critical
review.
