THE DISSOLUTION EFFICIENCY FOR DIFFERENT STREAM LIMING METHODS AND TECHNOLOGIES
The dissolution efficiency for different stream liming methods can be shown to depend upon a small number of parameters. They are several orders of magnitude more important than other parameters influencing the dissolution efficiency. The parameters are:
– Particle size distribution
– Initial pH-value
– Dose intensity
– Degree of wet slurrying
The particle size distribution and the degree of wet slurrying are the only free variables and when they are determined, the others will be determined by the conditions at the dosing site. The way to influence the dissolution efficiency, and accordingly the cost of neutralization, will be to vary the particle size distribution of the powder used for dosing. This way the cost optimum may be located.
