Title:
SYSTEM AND METHOD FOR PRECIPITATING SALTS
Document Type and Number:
WIPO Patent Application WO2002062705
Kind Code:
A3
Abstract:
A system and method for producing salts using a crystallizer with an integrated column is disclosed. In the column, liquid, containing one reactant, absorbs a second reactant, from the gas stream. The second reactant reacts with the first reactant to produce salt. Liquid leaving the column and rich in salt, collects in the crystallizer. Conditions within the crystallizer promote nucleation and crystal growth. A recirculation system withdraws a portion of liquid from the crystallizer for introduction into the column.
