摘要

The use of renewable sources to produce chemical compounds is a hot issue, and takes more importance when considering the valorisation of a waste stream. Acetic acid is a useful chemical commodity that can be produced by biotechnological treatment of waste streams. Unfortunately, is rather diluted and its recovery by distillation is quite energy demanding. There are many experimental studies about the capabilities of the basic trioctylamine mixed with organic non-polar compounds to extract acetic acid. Usually the literature studies focus on finding a solvent that requires a low solvent flow rate during the extraction. In this paper, a suitable and simple solvent screening method for reactive extraction is proposed. The overall separation process including also the solvent recovery is considered, at the contrary of available studies that focus only on the extraction operation. For the first time, the DSE concept is applied to a process including other types of separations units besides distillation columns. The obtained results show that the best solvent is 1-octanol, which is in agreement to literature data in which it is the reference solvent.
