Abstract: The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.

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: 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 passing a natural gas feedstream though a regenerable adsorbent media which adsorbs the NGLs to provides the methane rich natural gas product. The regenerable adsorbent media of the present invention is a cross-linked macroporous polymeric adsorbent media.

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.
