ABSTRACT:
A process for recovering sodium citrate from a solution utilized in an absorption/stripping process for SO.sub.2 recovery, which involves cooling a portion of the stripping solution to precipitate sodium sulfate, which is separated from the mother liquor. Thereafter, the mother liquor portion is subjected to an evaporative crystallization to precipitate sodium citrate, which is reintroduced along with fresh absorbent solution into the SO.sub.2 absorption/stripping process.
