Abstract
A process for manufacturing purified glycerol including the steps of providing a starting glycerol fraction comprising glycerol, water, and fatty acid methyl esters, subjecting the glycerol fraction to a partial evaporation to form an evaporated fraction including glycerol, water, and fatty acid methyl esters, and a remainder fraction including glycerol, condensing the evaporated fraction to form a liquid, subjecting the liquid evaporated fraction including glycerol, water, and fatty acid methyl esters to a liquid-liquid separation step, resulting in the formation of a fatty acid methyl ester fraction and a glycerol-based fraction including glycerol and water. The process makes it possible to efficiently separate the fatty acid methyl esters from glycerol, without the need for complete glycerol distillation. Also provides glycerol fractions suitable for use as carbon source in fermentation processes, without problems in down-stream processing, and without the need for cost-intensive purification steps for the glycerol.
