How is the mother liquor circulation rate calculated in an evaporation crystallization system?
The concentration factor is calculated based on the initial concentration and the final concentration, while the circulation volume of the concentrated mother liquor is determined using the amount of raw material and this concentration factor. It is particularly important to check whether there are any other harmful substances in the material that do not evaporate; if such harmful substances are present, it is necessary to determine the proportion of the mother liquor to be removed based on their concentrations.
Is there an example of the calculation process?
First, determine the salt content at the endpoint of evaporation concentration, that is, the salt content in the supersaturated solid-liquid mixture, including both the saturated solution and the solid salts that have precipitated； The recycled mother liquor corresponds to the saturated solution at the corresponding temperature separated by the centrifuge
