DIALYSIS

If such a mixture is placed in a sack made of parchment,

collodion, or cellophane and suspended in water, the ions and

small molecules pass through the membrane, leaving the

colloidal particles in the sack. Separation by dialysis is a slow

process, depending for its speed on the differences in particle size and diffusion rates between

REVERSE OSMOSIS

The process of reverse osmosis forces the water with a

higher concentration contamination into the tank containing

water with lower concentrations .A high-pressure water is

used to "transform" the natural osmotic process, with the

semi-permeable membrane, it allows the passage of water

and reject most of the other ingredients. Ion exclusion

process in which the concentration of ions in the surface

membrane of the barrier allows other water molecules to pass through and not including other

materials

GAS PERMEATION

Gas Permeation is one of separation process which involved

at least two components where those are fed to the

membrane that has a higher permeation flux for at least one

of the components in the feed mixture.The difference in

 partial pressure between the feed side and the permeate side

of the membrane acts as a driving force for components to

 permeate.Hence, the permeate side of the membrane is maintained at a substantially lower

 pressure than the feed side.In the gas permeation process, the operating pressures may be

very high. Therefore, there may be substantial differences in the feed, retentate, and

 permeate temperatures due to the Joule-Thompson effect.

ULTRAFILTRATION 

Ultrafiltration with an abbreviation of UF and it is

commonly used in cross-flow or dead-end mode of

separation application in industry such as purifying

of proteins solutions or any process that require

macromolecular purification of continuous systems.It works by which hydrostatic pressure

forces a liquid against a semipermeable membrane.Suspended solids and solutes of high

molecular weight are retained, while water and low molecular weight solutes pass through the

membrane.The retained substances used are captured on the membrane surface and removed

from the module continuously or periodically, depending on the filtration mode type and

considering whether it is concentrate or in the backwash effluent.

REAL APPLICATION OF THE MEMBRANE IN THE INDUSTRY

Membrane Technology and Research, Inc. (MTR), based in Menlo Park, CA, is a privately

owned developer, manufacturer, and supplier of customized membrane process solutions.

MTR was founded in 1982 as an R&D company with a long-term goal of developingmarketable membrane technologies, especially in the newly-emerging field of industrial gas

separations.MTR is a world leader in the development and production of membrane-based

separation system fot the petrochemcial,natural gas and refining industries. The MTR group

conducts application analyses, develops process designs, and manages field tests of

innovative membrane systems.Ultrafiltration membrane process is used in this production.

Recently the development principle membrane product of this company is include the

following:

• VaporSep® 

systems to remove organic vapors from air and nitrogen

•NitroSepTM and fuel 

gas conditioning systems for natural gas treatment

• Hydrogen recovery systems for refinery and other applications MTR’s current R&D

extending use of membranes to carbon sequestration and biofuels separations.

Field test unit for NGL

recovery from natural gas 

VaporSep® membrane vapor recovery
