What is a Membrane?


A membrane is a permeable barrier that selectively permits entities to pass through it. Gas Land utilizes membrane technology to separate air (composed of 20.8% Oxygen , 78% Nitrogen, and 1.2% other gases) to produce a Nitrogen rich gas product.  Gas Land's membrane separator modules consist of a cylindrical housing with densely packed hollow fibers. Pressurized, dried, and filtered air enters the membrane module and fast gases such as Oxygen permeate through the fibers leaving behind  Nitrogen rich gas. The separation process depends on several factors such as the size of the molecules, speed of the molecules, and chemical interactions with the fibers. Typical Gas Land Nitrogen Generation Systems are designed to deliver between 96% and 98.5% Nitrogen purity depending on the customer’s needs. The primary advantage of membrane gas separation is that the process does not require any moving parts. This reduces maintenance and repair costs and ensures the system continues to perform for years to come.
