Question

what is a method for purification of hydrogen ​

Answer 1

Answer:

Applications for hydrogen generation plants

• Metallurgical and steel industry
• Petrochemical and refining industry
• Glass and float glass manufacturing
• Chemical and pharmaceutical industry
• Production of H2O2
• Food industry
• Electronics industry
• Technical gases

Answer 2

Answer:

Purification Equipment:

A range of Deoxidisers (vessels filled with catalyst).

Automatic and manual hydrogen addition systems.

High Pressure hydrogen purification plants

Since the introduction of the technique for hydrogen purification by selective diffusion through palladium alloy membranes several other purification techniques have been developed. These fall broadly into three categories:

Chemical—Catalytic Purification

Physical—Metal Hydride Separation

Pressure Swing Adsorption

Cryogenic Separation.

Selective Diffusion—

Noble Metal Membrane Diffusion

Polymer Membrane Diffusion

Solid Polymer Electrolyte Cells.

Each technique has limitations as well as advantages, which are summarised in the Table, and it is appropriate to consider these in a comparative way, prior to discussing the development and status of noble metal membrane diffusion in more detail.
