The Hydrogenation Process | Eurotherm by Schneider Electric

The use of hydrogen requires precautions against creating an explosive mix of hydrogen and air. Typically, a hydrogenation vessel undergoes a pressure test followed by several nitrogen purges before hydrogen is introduced. Similarly, at the end of the reaction process, the vessel is purged with nitrogen in order to leave it in a safe condition.
