Hydrogen recovery in a distributed distillation system

A process for recovering hydrogen from a mixed hydrocarbon stream wherein the mixed hydrocarbon stream is subjected to a separation technique to produce a substantially hydrogen enriched stream, which is then recovered as hydrogen product. A process for providing refrigeration duty to the process is...

Beschreibung
Zusammenfassung:	A process for recovering hydrogen from a mixed hydrocarbon stream wherein the mixed hydrocarbon stream is subjected to a separation technique to produce a substantially hydrogen enriched stream, which is then recovered as hydrogen product. A process for providing refrigeration duty to the process is also disclosed, wherein a substantially methane enriched stream arising from the separation technique is expanded to provide cooling duty for the process.
