The use of hydrogen gas is growing in demand in various markets and applications. This growth is increasing rapidly as the global requirement for a cleaner energy source is developed. Hydrogen gas is used in industrial processes, there are several examples, such as fuel cells for electricity generation and powering vehicles. Outside of power generation, hydrogen is used by industry for refining petroleum, treating metals, producing fertilizer and other chemicals, and processing foods.

A common requirement for all identified applications is that hydrogen gas requires ‘cleaning’, providing protection to the process. The level of removal of particulate within the gas stream has a direct relationship to the application requirements. There are several techniques available to obtain the required filtration and purification efficiencies that are unique to the application. These include mechanical/depth filtration, activated carbon, membrane and chemical. Other hydrogen purification methods are available, such as pressure swing adsorption, gas membrane separation and electrochemical separation.

Applications
• Fuel cells
• Power generation
• Petroleum refinement
• Metal treatment
• Fertilizer/chemical production
• Food processing

Parker glass microfibre filter elements are designed for highly efficient particulate removal. A random bed of borosilicate glass fibres are held in a rigid structure by the fluorocarbon resin binder. Typically used for solids and relatively large amounts of suspended liquids in gases. Offering excellent chemical resistance, and temperature resistance to 150°C, these cartridges have thick walls for improved coalescing efficiency and are ideal for use with hydrogen gas both depth and coalescing applications.
