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: A method of fused filament fabrication (FFF) additive manufacturing comprises employing a thermoplastic blend comprised of high density polyethylene and a second thermoplastic polymer, wherein the second polymer is a low density polyethylene (LDPE), functionalized polyolefin or combination thereof and the amount of high density polyethylene to the amount of second thermoplastic polymer by weight is a ratio from 1.5/1 to 20/1. LDPE means a polyethylene that have been radically polymerized at high pressure. The method allows for the additive manufacturing article that retains the desirable mechanical properties of HDPE without experiencing the problems inherent in FFF printing of HDPE or use of solid fillers. In a particular embodiment, the additive manufactured article has a continuous phase and the second thermoplastic polymer is present as a discontinuous phase within the additive article manufactured article and the filament used to make the article.

Abstract: An additive elastomeric manufactured part having an elongation at break of at least 50% may be made by a method comprising the following. A material comprising a prepolymer and filler is first 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. Subsequent layers are then formed on the initial layer by repeating the dispensing and movement on top of the initial layer and layers that follow.
