Customer achieves payback in under two-and-a-half months with compact heat exchanger

In an ongoing effort to improve plant efficiency and reduce operating costs, a pulp mill in Georgia, USA, decided to use a compact heat exchanger to preheat its chlorine dioxide solution with waste heat from its bleach plant.

The ideal heat exchanger for this particular application would combine the high efficiency and high shear found in corrugated plate-and-frame technology with the reliability and convenience of a welded, gasket-free, design. In addition, this heat exchanger must have the adequate channel spacing to handle the small concentration of fibers present in the Filtrate stream.

After a careful evaluation of available technologies, this pulp mill chose an Alfa Laval
Compabloc welded heat exchanger.
