Gas transfer is a major application of process blowers. Gases are recovered for treatment, elimination or are used in chemical processes. (reactivation gases recycle)
Here are some examples of chemical processes that need gas conveying: acetylene, hydrogen in carbon black manufacturing, electrolysis (weld, ore of bauxite) or mercury processes.
The transfer of gas also takes place in reactor degassing and pipe purging with nitrogen and inert gases, in gases filtration loops with helium, krypton or nitrogen, or in the electrolysis and mercury processes.
