Product recovery in surfactant-based separation processes: Pervaporation of toluene from concentrated surfactant solutions

Preparation and characterization of yellow Monascus pigments

“…Organic compound with low boiling point can be easily recovered by evaporation due to the high boiling point of most surfactants [27]. For ionizable compounds, adjustment of pH in the dilute phase of a cloud point system is also a conventional strategy for back-extraction of ionizable products from nonionic surfactant micelle aqueous solution [28][29][30].…”

Transferring of red Monascus pigments from nonionic surfactant to hydrophobic ionic liquid by novel microemulsion extraction

“…Based on the character of surfactant, degradable surfactant can be removed before the further recovery of product, such as biodegradation of bio-surfactant for de-emulsification during microbial fermentation [26]. Based on the character of solute, low boiling point product can be easily recovered by evaporation due to the high boiling point of most surfactants [27,28]. Especially, nonionic state of organic compound prefers to solubilization in nonionic surfactant micelles while the solubilization of the corresponding ionic state in micelles is very limited.…”

In situ product recovery techniques aiming to obtain biotechnological products: A glance to current knowledge

“…The molecules in the feed mixture have different affinities for the membrane, and even a low‐concentration component in the feed stream can be highly enriched in the permeate [23]. On the other hand, it is also considered a membrane‐based separation process associated with distillation and condensation, in which the separation is based on interactions of unique components with polymer membranes [24].…”
