Abstract:
Membrane Aromatic Recovery System (MARS) is a technology for recovery of phenol from wastewater streams. This technology recovers aromatic acid and bases from water and wastewater. In many petrochemical industries, aromatic compounds like phenol and benzene in different concentrations is discharged to wastewater. This process is combination of membrane technology and extraction. The process comprises a stripping vessel, where phenols are extracted through nonporous membranes and concentrated into a NaOH solution as phenolate, and a two-phase separator in which the solution collected from the stripping vessel is separated into a phenolic phase and an aqueous phase by adjusting pH to acidic conditions with the addition of an acid like HCl. In this paper, the application of this method in the petrochemical wastewater which has a high concentration of aromatic compounds is studied.
