Bleach plant
This ECF bleach plant was supplied for the 1,900 t/d hardwood fiberline at Stora Enso’s Imatra mill in Finland. The
delivery also included brownstock washing, oxygen delignification, and deknotting/screening.
TurboFeed has made the breakthrough and
is today the standard solution in chip feeding systems
into the digester. The new developments of
the DD Washer show remarkable progress with
regard to reliability, washing efficiency, and capacity.
These improvements are available for modernizations
and upgrades of existing lines, in addition
to new fiberlines.
Recent start-ups and sales of the new coarse/
fine screening systems (combined unit) is a clear
indication of market acceptance of this new product.
The combined unit further reduces screen
room costs.
The Division is also continuing to focus development
efforts on MC ® based technology throughout
the fiberline. Research is ongoing in the development
of fiberline processes for Southern hemisphere
wood species. Sophisticated simulation
programs are being utilized to improve upon washing
and cooking technologies. Advanced control
systems for all of the fiberline process areas are
being developed and tested.
