• In Western Europe, we annually use more than fifty million tonnes of cardboard and
paper.
• The European cardboard and paper industry processes some twenty million tonnes
of paper waste each year.
• That is approximately 35% of the total cardboard and paper consumption. Fibre is
needed for the production of cardboard and paper.
• Western European cardboard and paper manufacturers retrieve 35% of the fibre
they require from used paper.
• During the production process, high-fibre sieve water is discharged which is often
heated by heat exchangers.
• With non fouling heat exchangers, fibre may still form a deposit on the heat
exchanging surface, forming a layer of fibre that hinders the heat exchange and
may even block the heat exchanger. In order to avoid this problem, it is possible to
inject the steam directly into the sieve water.
• However, this has the disadvantage that it thins the sieve water and results in the
loss of valuable condensate.

Challenge / question
High-fibre sieve water. Steam condensate. A
vertical shell and tube heat exchanger and... the
non fouling particle flow
• The client would like to supply the
heat of steam to waste water.
• This water contains approximately
250 mg of undissolved solids per
litre; 50% fibres and 50% lime.
• A conventional heat exchanger
will be faced with lime scale on
the heated tubes, leading to a
range of problems.
• How can this be resolved?

Our Solution
High-fibre sieve water. Steam condensate. A
vertical shell and tube heat exchanger and... the
non fouling particle flow
• We supply the client a Klarex® heat exchanger.
• Non fouling metal particals circulate through the
tubes of this vertical shell and tube heat
exchanger.
• They prevent lime scale from building up on the
sides of the tubes from the start.
• A multi-path distribution system ensures a
uniform distribution of the waste water (including
the non fouling metal particals) across the tubes.
• The system also ensures obtaining a
homogenous mixture.
• The volume of metal particals is set between 0%
and 7%.
• This client is only faced with lime scale in the
vertical tubes having upward pressure, when
they are heated.
• Therefore, the non fouling particle stream only
flows to the heat exchanger when process water
is being heated.
