Modelling of mass transfer of Zn through supported liquid membranes (SLM)
Research on mass transfer in liquid membrane permeation has still left some challenging aspects to be solved. Although discussed very intensively the published models are rarely comparable and suffer from a lack of accuracy. The program was started with research on the widely investigated and very common test system Znaqu / Bis(2-ethylhexyl) phosphoric acid/ sulphuric acid. Based on the experim...
متن کاملInvestigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System
In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
متن کاملSupported liquid membranes : instability effects
The instability behaviour of several supported liquid membranes (SLMs) has been studied for a system in which nitrate ions are removed from an aqueous feed phase and concentrated in a stripping phase. The composition of the aqueous phases and of the membrane liquid has been determined after the aqueous phases had flowed parallel to the membranes for a period of six days. From the experimental d...
متن کاملMass Transport in Thin Supported Silica Membranes
In this thesis multi-component mass transport in thin supported amorphous silica membranes is discussed. These membranes are micro-porous, with pore diameters smaller than 4Å and show high fluxes for small molecules (such as hydrogen) combined with high selectivities for these molecules with respect to larger ones. The chemical and thermal stability of silica membranes are favourable compared t...
متن کاملGas Separation by Supported Ionic Liquid Membranes
The use of ionic liquids (ILs) for gas separation processes recently has attracted much attention due to high solubilities of different gaseous species in ionic liquids [1]. The preparation of supported ionic liquid membranes (SILMs) is also reported for selective separation of different organic or gaseous compounds. Research activities have amongst others focused on CO2 separation from gas str...
