Abstract

Purification and concentration of the molasses is carried out by treatment with carbon dioxide at high pressure to form gas hydrate crystals, which are separated to give a purified sugar solution. A method for preparing sugar from sugar beet or sugarcane comprises extracting the sugar with water to form a sugar-containing molasses which is then purified and concentrated in order to recover the sugar by crystallisation. Purification and concentration of the molasses is carried out by treating it with liquid or gaseous carbon dioxide at -10 to +12 deg.C and 1-10 MPa to form gas hydrate crystals. These crystals are separated from the molasses, forming a purified sugar solution with an increased sugar content, which is further treated to recover the sugar crystals.
