Abstract: The present invention relates to a process for purification of a carbon dioxide feedstock, for example from a production well, which comprises carbon dioxide and gaseous and liquid C1+ hydrocarbons. Specifically, a carbon dioxide feedstream is passed through one or more separation unit wherein each separation unit removes one or more C1+ hydrocarbon from the carbon dioxide feedstream to provide a richer carbon dioxide gas stream. The process comprises one or more separation unit which 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 two or more separation units.

Abstract: Disclosed is an improved process for recovering condensable components from a gas stream, in particular, heavier hydrocarbons from a gas stream. The present process uses solid adsorbent media to remove said heavier hydrocarbons wherein the adsorbent media is regenerated in a continuous fashion in a continuous adsorbent media counter-current regeneration system using a stripping gas to provide a regenerated adsorbent media and a product gas comprising heavier hydrocarbons from a loaded adsorbent media. The improvement is the use of a portion of the product gas from the regeneration unit as the stripping gas.

Abstract: Disclosed is a method for running natural gas powered stationary combustion systems, such as an internal combustion engine, a furnace, a fired heater, a power plant, an incinerator, and the like. In one embodiment of the present method, ethane and heavier hydrocarbons or propane and heavier hydrocarbons (29) are removed (90) from a natural gas feedstream (3) to provide the methane-rich natural gas stream (5) used to fuel the stationary combustion system (100). One embodiment of this method provides for the use of a regenerable adsorbent media to remove the higher hydrocarbons which is regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.

Abstract: The present invention relates to a method of separating and recovering NGLs from a natural gas feedstream. Specifically, the present method allows for the separation of ethane and heavier hydrocarbons and/or propane and heavier hydrocarbons from a raw natural gas feedstream to provide pipeline quality natural gas. One embodiment of this method provides for the use of a regenerable adsorbent media which is regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.
