Hydrogen Membrane

Product Overview

The hydrogen membrane is a high-efficiency gas separation solution based on polymer membrane technology, designed for hydrogen purification and recovery.

The system utilizes advanced hollow fiber membrane modules to selectively separate and concentrate hydrogen from mixed gases, significantly improving hydrogen purity and recovery rates. With a compact structure, stable operation, and low energy consumption, it is widely used in chemical processing, refining, and industrial gas treatment applications.

Working Principle

The hydrogen membrane separates gases based on differences in solubility and diffusion rates through polymer materials. When mixed gas passes through the membrane module under a pressure difference, gases with higher permeation rates—such as H₂O, H₂, and CO₂—preferentially pass through the membrane and are enriched on the low-pressure side.

Gases with lower permeation rates—such as CH₄, N₂, and CO—remain on the high-pressure side. Through this selective permeation process, hydrogen is efficiently separated and purified from the gas mixture.
