Abstract: A buoyant apparatus that is capable of floating on liquid surfaces, such as bodies of water filled with waste byproducts. The buoyant apparatus supports a plurality of atomizers via rotatable and flexible arms that can achieve 180° adjustments with the respect to a longitudinal axis of the buoyant apparatus, such that the arms can be parallel to a surface of the body of water in both an extended orientation (with the atomizers deployed over the water surface) and a retracted orientation (with the atomizers stored within the surface area of the platform). In addition, the arms can achieve 360° rotational adjustments about the attachment point of the arms to the platform. The atomizers and arms are powered by low voltage direct current (DC) motors that can utilize solar power via photovoltaic cells such that the apparatus can be employed in remote locations without the need for a centralized power grid.

Abstract: A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olens to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.

Abstract: A clarifier of a wastewater treatment system is made more efficient and cost effective with an energy dissipating inlet (EDI) that removes the need for a conventional feedwell/EDI system. A central influent pipe has wastewater outlet ports under the liquid surface, the ports being surrounded by an efficient EDI surrounding the center pipe and extending outwardly therefrom. The EDI receives influent flow and directs the sludge outwardly and generally downwardly at reduced flow velocity. Series of baffles in the EDI help slow the flow velocity and disperse the sludge. In another embodiment a faucet-type EDI has discharge openings that disperse the sludge downwardly after it has flowed through sets of baffles above. Significant cost reductions in material and installation are realized by elimination of the conventional feedwell/EDI system.

Abstract: The present disclosure relates to systems and methods for separation of sulfurous material(s) from a multi-component feed stream. The systems and methods can comprise contacting the multi-component feed stream with a solvent in a contacting column so that at least a portion of the sulfurous material(s) is transferred from the multi-component feed stream to the solvent. A stream of a substantially purified gas can thus be provided along with a liquid stream comprising at least a majority of the sulfurous material. In particular, the solvent can comprise liquid carbon dioxide, which can be particularly beneficial for removing sulfurous materials from multi-component feed streams.
