Abstract: The present disclosure relates to a process for producing high-purity acrylic acid using azeotropic distillation and using water as an entrainer. This disclosure provides a process for separating acrylic acid from recovered feed streams which comprise acrylic acid and saturated organic acids including propionic acid. The resulting acrylic acid product is of sufficient purity to produce acrylate esters and high molecular weight acrylic acid polymers.

Abstract: Processes and systems for separating a mixture of three or more chemical components into multiple product streams each enriched in one of the components are provided herein. In some aspects, the present invention relates to processes for the separation of a chemical mixture including at least a heavy key component, an intermediate key component, and a light key component to form a product stream enriched in the light key component, a product stream enriched in the intermediate key component, and a product stream enriched in the heavy key component. Systems described herein may include one or more thermally coupled distillation columns including, for example, a dividing wall column, or a plurality of distillation columns arranged in a thermally integrated configuration.
