Description:
Dilute acetic acid wastewater streams are produced in large quantities by the synthetic organic chemical industry, for example, in the synthesis of terephthalic acid, the precursor of polyethylene terephthalate. Recovery of acetic acid from these wastestreams for in-process recycling of the acid would reduce waste and save valuable resources. This proposal describes the development of a process that combines selective dialysis followed by bipolar-membrane electrolysis to recover and concentrate this acid. Although the program focuses on acetic acid recovery, the technology could be applied to recovery and recycling of other weak acids such as acrylic acid, lactic acid, and phenols.Supplemental Keywords:
