Phenol separation-concentration from phenolic resin effluents using ultrafiltration membranes for phenol recovery was studied for the purposes of this work. Ultrafiltration membranes, used at both laboratory and pilot scale, provided the requisite experimental data for the creation of an industrial-level proposal. The feasibility of the large-scale use of membranes was assessed, and phenol rejection and permeation at the industrial level were predicted by calculating mass transfer coefficients, using diffusion models and the Lévêque relationship. DWSIM - Open Source Chemical Process Simulator software was used to predict the rejection and permeation of phenol at the industrial scale. Scale experiments revealed that 82-84% of phenol was recovered; the mass transfer coefficient indicated a high level of water permeation through UF membranes, with a prediction of phenol rejection with an 8% margin for error, relative to pilot scale data. The membrane area for industrial requirements resulted in 9 m2 with 3000 Da. According to the simulation software, the phenol flux in the reject and permeate streams was consistent with experimental data, demonstrating the similarity between the membrane scales.
