  • Patent number: 7220435
    Abstract: The present invention relates to a simple, economical, and efficient cyclic process for producing rhombic dodecahedron shaped glycine enriched, free flowing common salt from brine, said process comprising steps of adding glycine of concentration ranging between 10 to 25% to the saturated brine, evaporating the saturated brine containing glycine to obtain crystals having high content of glycine, with mother liquor, washing the crystals with saturated brine to obtain rhombic dodecahedron shaped glycine enriched common salt having glycine content ranging between 0.5 to 1.0% and a washed brine, combining the mother liquor and the washed brine to obtain resulting brine, subjecting the resultant brine to solar evaporation, and repeating the steps of (iii) to (v) to obtain rhombic dodecahedron shaped glycine enriched common salt from brine with glycine concentration ranging between 0.5 to 1.0%.
