García Villaluenga, Juan Pedro ; Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz ; Seoane Rodríguez, Benjamín ; Mengual Cabezón, Juan Ignacio | Elsevier Science BV | 2005-12The effect of the membrane thickness on the pervaporation separation of methanol and methyl tertiary butyl ether mixtures through membranes was studied. Membranes of a wide range of thicknesses were prepared from two different polymers: cellulos[...]texto impreso
Godino Gómez, María Paz ; Peña, Luis ; Ortiz de Zárate Leira, José María ; Mengual Cabezón, Juan Ignacio | Taylor & Francis Inc | 1995Water transport in the vapor phase through a porous hydrophobic membrane has been studied in different experimental situations. Pure water and/or different aqueous solutions of sodium chloride, ranging from 0.5 to 5 mol/L, were employed on both [...]texto impreso
Barragán García, Vicenta María ; Ruiz Bauzá, Carlos ; Mengual Cabezón, Juan Ignacio | Academic Press Inc Elsevier Science | 1994-12Electro-osmotic fluxes of water through two cation-exchange membranes have been measured under different experimental conditions. The influence of unstirred solution layers adjoining the membrane surfaces on the obtained values has been studied [...]texto impreso
Khayet Souhaimi, Mohamed ; García Villaluenga, Juan Pedro ; Valentin, J. L. ; López Manchado, Miguel Ángel ; Mengual Cabezón, Juan Ignacio ; Seoane Rodríguez, Benjamín | Elsevier Ltd. | 2005-11-14The effects of silica and silane modified silica fillers on the pervaporation properties of poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) dense membranes have been studied. Crystallinity, thermal and mechanical properties of unfilled and filled [...]texto impreso
García Villaluenga, Juan Pedro ; Khayet Souhaimi, Mohamed ; Lopez Manchado, M. A. ; Valentin, J. L. ; Seoane Rodríguez, Benjamín ; Mengual Cabezón, Juan Ignacio | Elsevier | 2007-04Polypropylene membranes modified with natural and organically modified montmorillonite clays were prepared. The permeability, diffusivity and solubility of helium, oxygen and nitrogen were determined for the unfilled and filled membranes over th[...]texto impreso
Mengual Cabezón, Juan Ignacio ; Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz | Elsevier | 2004-02-04In the membrane distillation (MD) literature, the heat transfer coefficients of the boundary layers are usually estimated from well known heat transfer empirical correlations developed for non-porous and rigid heat exchangers. A difference betwe[...]texto impreso
Peña, Luis ; Godino Gómez, María Paz ; Mengual Cabezón, Juan Ignacio | Elsevier Science BV | 1998-05-27A method is proposed that permits to evaluate the net membrane distillation coefficient. The method, which completes and is based on a model previously reported, emphasizes the influence of the unstirred boundary layers on the membrane distillat[...]texto impreso
Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz ; Mengual Cabezón, Juan Ignacio | Walter de Gruyter & CO | 2001The physical nature of water flow, in vapour phase, through the pores of a microporous partition has been studied according to the possibilities suggested by the Kinetic Theory of Gases. A method is proposed that permits to decide which is the m[...]texto impreso
García Villaluenga, Juan Pedro ; Godino Gómez, María Paz ; Khayet Souhaimi, Mohamed ; Seoane Rodríguez, Benjamín ; Mengual Cabezón, Juan Ignacio | 2004-05-12Pervaporation separation and swelling experiments of methanol/methyl tert-butyl ether mixtures were performed by using a flat-sheet, dense poly(2,6-dimethyl-1,4-phenylene oxide) membrane prepared from a chloroform casting solvent. The effect of [...]texto impreso
García Villaluenga, Juan Pedro ; Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz ; Seoane Rodríguez, Benjamín ; Mengual Cabezón, Juan Ignacio | American Chemical Society | 2003-01-22The pervaporation characteristics of toluene/methanol, toluene/ethanol, and toluene/propanol mixtures through a linear low-density polyethylene membrane were investigated at different feed compositions. These characteristics were obtained from q[...]texto impreso

C. ; Matsuura, T. | Elsevier | 2004-10-15Dense flat-sheet membranes were prepared from poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) using the casting solvents chloroform and 1,1,2-trichloroethylene. X-ray diffraction, tapping mode atomic force microscopy (TM-AFM), and contact angle stu[...]texto impreso
Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz ; Mengual Cabezón, Juan Ignacio | Elsevier | 2003-08-01Sweeping gas membrane distillation was investigated as a possible technique for desalination by using a shell-and-tube polypropylene membrane module. Humid air was employed as the vapor carrier gas and the feed solution was circulated in counter[...]texto impreso
Khayet Souhaimi, Mohamed ; Godino Gómez, María Paz ; Mengual Cabezón, Juan Ignacio | 2002-07-02The sweeping gas membrane distillation process was analyzed in a plate and frame membrane module, and a method clarifying the contribution of each boundary layer separately was developed. The temperature polarization coefficients of the fluid ph[...]texto impreso
Godino Gómez, María Paz ; Peña, Luis ; Mengual Cabezón, Juan Ignacio ; Rincón, C. | Elsevier Science BV | 1997-02The possibility of obtaining pure water by membrane distillation, from brines rejected in other water production operations has been considered. Membrane distillation experiments have been carried out by using two PTFE porous hydrophobic membran[...]
