QualiCal for a Sustainable development

A functioning and resilient infrastructure is the foundation of every successful Company. To meet future challenges, our industries and infrastructure must be upgraded. For this, we need to promote innovative sustainable technologies

Within the spirit of #QualiCal R&D corporate vision, upgrades since 1998 its , in order to optimize the hydration process efficiency producing a wider spectrum of hydrated lime products.

Traditional Hydration plant

Operations were limited as follows, when the slaking plant was run with highly reactive quicklime from the PFR kiln (t60 from 18 to 30 seconds):

  • The proportion of oversize particles (residue at 0.090 mm) in the unrefined slaked lime increased up to 60%-75%
  • The plant output is reduced by up to 50%
  • The plant output rate had to be reduced to approx. 2.5 tons per hour.
  • Power consumption at 25 kWh/ton was too high.

SPYDRO-RTC features

QualiCal vision is to upgrade lime infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes.

In order to overcome the limit of existing technology, QualiCal designed and manufactured since 1998 its brand new

  • is composed by an high speed pre-mixing reactor (equipped V-shape and T-shape blades more than traditional shape blades) and by 2 seasoning stages that, in combination with the ยฎ โ€” reaction temperature control features โ€” makes suitable to and
  • โ€” is provided also by QualiCal patented dedusting filter on the side to reduce the emission it atmosphere within the state of the art environmental limits.

Results

  • When slaking highly reactive quicklime, the proportions of (residue on an 0.090 mm screen).
  • Power consumption reduced <15 kWh/ton.

Further improvements and upgrades

Water recover with QualiCUBE โ€” AQUA module

is provided also along with to optimize the usage & recovery of process water.

Water recovery with QualiCUBE โ€” Cal.DO module

In full line with SDGC, QualiCal upgraded hydration plant by a dedicated module suitable to recovery the from the hydration process.
