Membrane process

In this paper a general review on different membrane processes and membrane reactors was done. As the main aim of this paper is to review the application of membrane processes in petrochemical industry, processes such as olefin/paraffin separation, light solvent separation, solvent dewaxing, phenol

The contamination of water by sulphate is a pollution problem that has increased in severity in recent decades. The behaviour of cellulose acetate membranes in the treatment by reverse osmosis of aqueous sulphate solutions is described. Experimental essays were performed in a commercial cross flow t

This work deals with the selective demineralization of natural saltwaters by electrodialysis on specific membranes with the aim of preparing an “isotonic” water of blood plasma, i.e., of the same saline composition as blood, with potential applications in the field of health. Preliminary experiences

The effect of ozonation on permeate flux was studied by using a polysulfone ultrafiltration membrane. The filtration was carried out by permeating chemical wastewater treated by combined ozone and membrane filtration methods under 3 kgf/cm2 until steady-state flux was obtained. Then, the ozone of co
