A process for purification of a carbon dioxide feedstock that includes carbon dioxide and gaseous and liquid C+ hydrocarbons. Specifically, a carbon dioxide feedstream is passed through one or more separation unit, each separation unit removing one or more C+ hydrocarbon from the carbon dioxide feedstream to provide a richer carbon dioxide gas stream. The one or more separation unit employs an adsorption media and has an adsorption step and a media regeneration step.

The present invention relates to an aqueous alkanolamine solution and use therein a process for the selective removal of hydrogen sulfide from gaseous mixtures comprising hydrogen sulfide. The aqueous alkanolamine solution consists of &#x2014;an amino compound with the formula: RRNCHCH(OH)CHOH wherein Rand Rindependently represent methyl, ethyl, propyl or isopropyl groups &#x2014;and bis(2-hydroxyethyl)methylamine, &#x2014;optionally one or more of a physical solvent, an antifoaming agent, an antioxidant, a corrosion inhibitor, a film former, a chelating agent or a pH adjuster and &#x2014;water The process for selectively removing hydrogen sulfide, comprising the step of contacting the gaseous mixture with the aqueous alkanolamine solution, preferably wherein the temperature of the aqueous alkanolamine solution is equal to or greater than 140&#xb0; F.

Disclosed is a method of sequentially separating and recovering one or more NGLs () from a natural gas feedstream (). Specifically, a raw natural gas feedstream () is passed through two or more NGLs separation unit () wherein each separation unit removes one or more NGLs from the natural gas feedstream to provide a methane-rich natural gas supply (). Each separation unit employs an adsorption media and has an adsorption step and a media regeneration step wherein the regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process. One embodiment of this method provides for the use of a different regenerable adsorbent media in each separation unit.

Disclosed is an improved process for regenerating solvent used to remove contaminants from a fluid stream. Said process comprises a solvent regeneration system () comprising a rich/lean solvent stripper column (), reboiler (), condenser (), and reflux receiver () wherein the improvement is the locationof the condensed stripper gas return from the reflux receiver.
