Abstract: A process for purification of a carbon dioxide feedstock that includes carbon dioxide and gaseous and liquid C1+ hydrocarbons. Specifically, a carbon dioxide feedstream is passed through one or more separation unit, each separation unit removing one or more C1+ 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.

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: Disclosed is a method of sequentially separating and recovering one or more NGLs (129, 229) from a natural gas feedstream (3). Specifically, a raw natural gas feedstream (3) is passed through two or more NGLs separation unit (100, 200) wherein each separation unit removes one or more NGLs from the natural gas feedstream to provide a methane-rich natural gas supply (205). 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.

Abstract: A method is disclosed for the separation of ethane and heavier hydrocarbons or propane and heavier hydrocarbons from natural gas to provide a methane-rich natural gas stream and less volatile natural gas liquids (NGLs). This method provides for the use of a regenerable adsorbent media comprising a porous cross-linked polymeric adsorbent, a pyrolized macroporous polymer, or mixtures thereof, which is regenerated by a pressure swing adsorption (PSA) process, temperature swing adsorption (TSA) process, or combination of the two. Said regeneration step may be operated as a batch process, a semi-continuous process, or preferably as 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.

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 a method to reduce the environmental impact of flaring a natural gas feedstream by removing and recovering some or all natural gas liquids (NGLs) (29) from the natural gas feedstream (3) prior to flaring (100). One embodiment of the present method provides for the use of a regenerable adsorbent media to remove the NGLs from the natural gas which can be regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.
