INTRODUCTION Separation by the use of membranes are becoming increasingly important in the process industries. In this relatively new separation process, the membrane acts as a semipermeable barrier and separation occurs by the membrane controling the rate of the movement of various molecules between two liquid phase, two gas phases, or a liquid and a gas phase.

Membrane gas separation

Membrane gas separation

While polymeric membranes are economical and technologically useful, they are bounded by their performance, known as the Robeson limit. This limit affects polymeric membrane use for CO2 separation from flue gas streams, since mass transport becomes limiting and CO2 separation becomes very expensive due to low permeabilities. Membrane materials have expanded into the realm of silica,

INTRODUCTION Membrane separations are based on solid, semi permeable barriers, through which a part of the material is led. Each component in a mixture has different permeability, which depends on the molecular size, pore sizes in the membrane and chemical characters of the components and the membrane and their interactions.

Introduction to Liquid Liquid Extraction. Liquid liquid extraction (also known as solvent extraction) involves the separation of the constituents (solutes) of a liquid solution by contact with another insoluble liquid. Solutes are separated based on their different solubilities in different liquids. Separation is achieved when the substances constituting the original solution is transferred from the original solution to the other

Separation processes processdesign

Separation processes are based on the theory of vapor liquid equilibrium. This theory states that streams leaving a stage in a separation process are in equilibrium with one another. The idea of equilibrium revolves around the idea that when there is vapor and liquid in contact with one another they are in constantly vaporizing and condensing.
