a pumping system ensures the mixing of sludge in the structure and a hot water tubular exchanger
allows the heating thereof at 37 c.The sludge circulation pipes are obsolete (breakages due to abrasion) the work consists to replace all the pipelines as well as the valves and valves of the pumps for the two digesters.
Cataract Steel Industries is ASME certified, and all designs are based on Tubular Exchanger
Manufacturers Association standards.
This enables the Compabloc to pack as much heat transfer capability into just 3 cubic metres as an equivalent, conventional tubular exchanger
with a heal transfer area of 1000[m.sup.2].
"If refiners employed Plate Heat Exchnagers instead of tubular exchangers
, the difference in efficiency levels (thermal efficiency is 200-300% greater in sugar applications) means that they could employ lower grade heat sources such as condensate or low pressure vapour in place of expensive steam for many parts of the process."
, where the product flow is more straightforward than plate-and-frames, can handle high incoming pressure more easily.
