Regeneration of olefin treating adsorbents for removal of oxygenate contaminants

Processes for eliminating oxygenates and water from a light hydrocarbon processing system, wherein oxygenates are removed from a light hydrocarbon stream by adsorption of the oxygenates on an oxygenate adsorption unit to provide a deoxygenated hydrocarbon stream, the oxygenate adsorption unit is reg...

Beschreibung
Zusammenfassung:	Processes for eliminating oxygenates and water from a light hydrocarbon processing system, wherein oxygenates are removed from a light hydrocarbon stream by adsorption of the oxygenates on an oxygenate adsorption unit to provide a deoxygenated hydrocarbon stream, the oxygenate adsorption unit is regenerated via a regenerant stream to provide an oxygenated regenerant stream comprising the oxygenates, and the oxygenated regenerant stream is subjected to hydro-deoxygenation to convert the oxygenates into paraffins and water, wherein the water may also be permanently removed from the system.
