Plant requiring large quantities of lime slurry, could be cost-effective if the quick lime is slaked on site. The process consists of injecting quick lime in an agitated slaking tank maintaining high concentration. The exothermic reaction by mixing quick lime with water creates heat and steam.
A dust scrubber located on top of the tank removes this excess of steam and creates proper tank aeration. The process is automatically controlled and secured through temperature probe, electronic flowmeter and ultrasonic level probe. Once the quick lime is slaked, lime slurry overflows into a dilution tank in which water is added to obtain final concentration in order to be pumped.
