“…The European Community sets the maximum amount of phenol in wastewater by lower than 1 ppm [2]. Several methods have been proposed to separate phenol from wastewater such as membrane techniques [3], solvent extraction [4], biological treatments [5], heterogenous photocatalysis [6] and adsorption [7][8]. Adsorption is one of the methods that are efficient, low in cost and high in capacity [9].…”

“…Such a process is basically made up of three unit operations: (a) extraction of phenol from the contaminated stream by a solvent, which gives an extract and a raffinate phase, (b) phenol separation from the solvent (extract), and (c) separation of the solvent present in the treated effluent (raffinate) [20]. The operation of phenol recovery from the solvent can be performed in different ways, among which is a second extraction by solvent, distillation, evaporation or chemical reaction [21].…”

The aim of this work is the study of batch liquid-liquid extraction of phenol from aqueous solutions in a bench-scale well-mixed reactor. The influence of the ratio of phase volumes, temperature, and rotational speed on phenol removal (0.72-1.1 % w/w) was investigated using methyl isobutyl ketone as an extracting solvent. For this purpose, the ratio of phase volumes were set at 0.1 and 0.2, the temperature at 10, 20, and 30°C, and the rotational speed at 300, 400, and 500 rpm. A physical model based on the material balance of the phases as well as the equation of mass flux between the phases allowed the estimation of the overall coefficient of mass transfer coupled with the superficial area. Moreover, it proved to fit, satisfactorily well, the experimental data of residual phenol concentration in the organic phase versus time under all the conditions investigated.

“…The governing principle in this technique is that when a solution containing a solute of interest is in contact with a solvent, the solute is distributed between two phases. Liquid-liquid extraction from aqueous solutions is a mature area of research for recovering both metal ions [59] and organic compounds [60]. However, the disadvantage remaining with this technique is that usually large amounts of solvent are required, and the extracted phase (solvent and solute) must usually be refreshed in a stripping step.…”

Abstract:Recovering valuable compounds from waste streams of bio-based production processes is in line with the circular economy paradigm, and is achievable by implementing "simple-to-use" and well-established process separation technologies. Such solutions are acceptable from industrial, economic and environmental points of view, implying relatively easy future implementation on pilot-and full-scale levels in the bio-based industry. Reviewing such technologies is therefore the focus here. Considerations about technology readiness level (TRL) and Net Present Value (NPV) are included in the review, since TRL and NPV contribute significantly to the techno-economic evaluation of future and promising process solutions. Based on the present review, a qualitative guideline for resource recovery from bio-based production processes is proposed. Finally, future approaches and perspectives toward identification and implementation of suitable resource recovery units for bio-based production processes are discussed.
