How Nitrogen Membrane works
Membrane nitrogen generators separate nitrogen from the atmosphere by passing compressed air through a permeable membrane. The technology relies on the principle of selective gas permeation. Each gas has a different permeation rate, so as the compressed feed air stream passes across the membrane, the gases with faster permeation rate (such as O2, CO2 & CO) to be separated from “slow gasses” such as nitrogen and the “fast gases” are released back to atmosphere at low pressure as waste gas. While the product nitrogen gas passes through a flow control and a non-return valve into the product receiver, or directly into the customer process line.
