• 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.
