Membrane Gas separation Nitrogen Oxygen membrane module
Product Description
Gas separation membranes are very fine hollow fibers through which different mixtures of gases are fed.
As the gases travel through the tubes, a process called selective permeation allows us to separate gases. At a closer look, gas separation membrane, the wall of each of these micro-thin hollow fibers, is an asymmetric filter made of various types of polymer. As different gases travel through the fiber, they come into contact with the membrane and permeate through it. The permeation rate of each gas is determined by its solubility in the membrane material and its diffusion rate. Gases with higher solubility and smaller molecules (fast gases) can pass through the membrane faster than other less soluble gases with generally larger molecules (slow gases). Gases which permeate faster and more are collected outside of the hollow fiber as permeates while gases which do not permeate so well and stay inside of the fiber until they reach the other end are separated out as retentates. Depending on the properties of the desired gas, either or both of permeates and retentates can be used.
Essential to a wide range of industrial processes and mechanical operations, securing a cost-efficient nitrogen gas is often anintegral part of system engineering. However, conventional methods such as high-pressure cylinders, liquid tanks and bulk storage involve significant logistical issues and increase costs. Membrane separation presents an economic alternative which enables on-site nitrogen generation from the air we breathe -78% of which is nitrogen at sea level.
Just as we can’t breathe without oxygen, many industrial and engineering processes require high-concentration oxygen as an essential ingredient. There are, however, also a wide range of applications where lower concentration of oxygen is sufficient without the expensive costs and risk of managing high-concentration oxygen supply. Membrane technology thus presents a cost-effective and safe alternative to high-pressure oxygen cylinders by enabling on-site oxygen generation for a variety of facilities such as clinical uses and air conditioning.
