Hydrogen - drivers

Hydrogen gas was first artificially produced in the early 16th century by the reaction of acids on metals. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance, and that it produces water when burned, the property for which it was later named: in Greek, hydrogen means "water-former".

Hydrogen-Hydrocarbon Recovery Process

The Hydrogen-Hydrocarbon Recovery Process uses a simple closed-loop reverse brayton gas expander (preferably using Nitrogen) to provide refrigeration for the recovery of hydrogen from hydrocarbons. Some or all of the cooling is provided by indirect heat exchange with the cold gas refrigerant generated in the closed-loop gas expander refrigeration cycle.
