Abstract: A method of selective sintering additive manufacturing comprises employing a powder comprising composite particulates comprising a first thermoplastic polymer and a second thermoplastic polymer interspersed with each other. In a particular embodiment, the first thermoplastic polymer and second thermoplastic polymer have differing absorbance of the irradiation used to sinter the particles when performing the additive manufacturing method. The first and second thermoplastic polymer may be continuously intertwined in within the particles or one of the polymers may be a discontinuously dispersed in a continuous matrix of the other polymer.

Abstract: A method of additive manufacturing is comprised of providing a material comprised of a ethyl cellulose polymer having an ethoxy content of 43% to 52% by mass and a plasticizer. The material is heated and dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base and successive layers of the material are adhered on the initial layer to form an additive manufactured part by repeating the aforementioned steps. The article formed of the ethyl cellulose polymer may be used in many applications such as those related to the pharmaceutical and food industries.

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 for separating natural gas liquids (NGLs) from a hydrocarbon gas mixture containing natural gas liquids and methane, comprising the steps of: i) providing a bed of adsorbent selective for NGLs over methane; ii) passing a hydrocarbon gas mixture containing methane and NGL through the bed of adsorbent to at least partially remove NGLs from the gas mixture to produce: (a) NGL-loaded adsorbent and (b) NGL-depleted hydrocarbon gas mixture; iii) recovering the NGL-depleted hydrocarbon gas mixture; iv) regenerating the NGL-loaded adsorbent by at least partially removing NGLs from the adsorbent; and v) sequentially repeating steps (ii) and (iii) using regenerated adsorbent from step (iv).
