Abstract

Methods and systems for producing high purity 3-hydroxypropionic acid (3-HP) from an aqueous medium, such as a fermentation broth, are described. Aqueous 3-HP solution can be purified by flash evaporation wherein the 3-HP is vaporized at an elevated temperature without conversion to acrylic acid. This process can be integrated with downstream processes for producing other chemical and consumer products.
