Graphene oxide (GO) membranes have shown promising gas separation characteristics that make them of interest for large-scale industrial applications. However, the gas transport mechanism for GO membranes is unclear due to inconsistent permeation and separation results reported in literature. GO membranes examined for gas separation were prepared on substrates and/or by synthesis methods that ar...

This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

This work is aimed at optimizing a Fischer-Tropsch Gas To Liquid (GTL) process by recycling compounds of the expelled gas mixture using zeolites for the separation. To that end, we have performed a computational study on four structures widely used in industry. A range of Si/Al ratios have been explored and the effects of their distribution assessed. The ability of the considered force fields a...

Introduction:  Parking areas that are gathering places for tank trucks are potentially dangerous places. This study analyzes accident consequences of oil products carriers, to check and compare the hazard radius with recommended separation distances. Methods: This descriptive-analytical study was carried out in 5 stages, including: scenario selection, determination of the accidents source para...
