STEAM CRACKING FEED GAS SATURATION

Dilution steam for steam cracking hydrocarbons to produce lower olefins is economically provided by saturating gaseous hydrocarbon feed with water at a temperature selected to achieve the particular steam to hydrocarbon ratio desired in the steam cracking step. Complete saturation of the feed gas is...

Beschreibung
Zusammenfassung:	Dilution steam for steam cracking hydrocarbons to produce lower olefins is economically provided by saturating gaseous hydrocarbon feed with water at a temperature selected to achieve the particular steam to hydrocarbon ratio desired in the steam cracking step. Complete saturation of the feed gas is ensured by injecting the gas into the flooded portion of an indirectly heated tubular saturation zone.
