Abstract: This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based or fossil fuel co-feed, or as a feedstock in the absence of a petroleum-based or fossil fuel co-feed. A mass balance accounting approach is employed to attribute the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit, which permits assigning circular product credit to product streams. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways.

Abstract: The sub-ambient solar desalination system includes a solar pond and a pressure reducing structure. The solar pond is adapted for receiving saltwater and heating the saltwater through direct exposure to solar radiation at atmospheric pressure. The pressure reducing structure is in fluid communication with the solar pond for receiving heated saltwater therefrom. The pressure reducing structure is configured such that pressure of the heated saltwater within a central portion of the pressure reducing structure is at sufficiently reduced sub-ambient pressure to undergo a phase change to produce pure water vapor and a concentrated brine solution. The pressure reducing structure has a vapor outlet for releasing the pure water vapor, which is collected in a fresh water tank and condensed into pure liquid water. The solar pond is in fluid communication with an outlet portion of the pressure reducing structure for recycling the concentrated brine solution back to the solar pond.

Abstract: The present disclosure is drawn to evaporation panel assemblies, systems, and methods. For example, a modular evaporation panel system can include a plurality of evaporation panels with individual evaporation panels including evaporation shelves that are laterally elongated, vertically stacked, and spaced apart; vertical support columns positioned along the evaporation shelves to vertically support and separate the evaporation shelves; female-receiving openings defined by multiple evaporation shelves and multiple support columns; and male connectors positioned at lateral ends of the evaporation panels. The male connectors can be releasably receivable by the female-receiving openings of an adjacent evaporation panel, thereby providing modular assembly and disassembly of multiple evaporation panels relative to one another.
Abstract: A water purifying and desalination system includes solar concentrators that receive a sunlight and direct the sunlight toward a collection element. The collection element absorbs and converts a solar radiation into thermal energy. A superheater tube enclosed by the heat collection element controls volume flow that partially fills the superheater tube with processed ocean water, which allows steam to escape into a portion of the superheater tube that generates electricity and additional processed ocean water.
Abstract: A method and system for treating and purifying saltwater contaminated by volatile compounds. The saltwater is evaporated resulting in a gas composed of water vapor and gaseous volatile compounds. The gas is condensed into a condensate containing the contaminated volatile compounds which is biologically treated to remove the volatile compounds thereby producing purified water. The latent heat released by condensing is used to evaporate the purified water into the atmosphere in an energy efficient manner.
Abstract: An animal food composition comprising cannabis and two or more ingredients selected from the group consisting of insects, a fiber-starch material, a binding agent, a density improving textural supplement, and a moisture improving textural supplement is described. The animal food composition may include bacteria, fungi, water, fermentation waste, spent microorganisms, an alcohol production coproduct, scales of fish, soft tissues of fish, radulae of mollusks, taurine, a fatty acid, or meat. The composition includes inflammation reduction properties, cannabis volatile feedstock components and wherein the cannabis includes powdered cannabis, ground cannabis, or dried cannabis.
Abstract: A method and a system for recovering nitrogen, and optionally phosphorus and/or potassium, from a liquid waste stream, such as a stream of urine or manure, or human urine is described. The method comprises passing the waste stream through a multi-compartment electrodialysis bipolar membrane (EDBM) system.
Abstract: Silicon carbide flat sheet filtration membranes are supported on one piece manifold/end cap structures. Ends of a large number of the parallel flat plate membranes are fitted into elongated end cap slots that are part of a single molded manifold/end cap structure, such a structure being at each end of the series of membranes. In addition, a one piece external frame module can be provided to receive the gang of flat plate membranes with attached manifold/end caps. In the event of a damaged plate, the plate can be removed and replaced along with a special end cap repair section. This provides advantages over prior arrangements with individual end caps for each module or potting of the flat plates into a box or chamber.
Abstract: Sometimes, a problem is obvious, everyone sees it, but nothing happens until someone decides to do something useful about it. Methods are herein provided for recovering heavy hydrocarbons from plastic materials and/or geo-formation. In one solution set, PVC waste materials are emulsified by an amine solvent in an aqueous phase, thereby extracting heavier hydrocarbons from the primary structure of PVC into the amine aqueous phase; followed by de-emulsifying the extracted heavier hydrocarbons by separating and recovering the amine solvent, and then separating the de-emulsified heavier hydrocarbons from the aqueous phase by a hydrophobic membrane.

Abstract: A system and method for removing ammonia from an ammonia-containing liquid is described. The system comprises a primary heat exchanger 12 for heating the ammonia-containing liquid to operational temperature, an ammonia stripper 14 for stripping ammonia from the ammonia-containing liquid from the primary heat exchanger and discharging it as ammonia-containing gas, and an acid scrubber 16 for reacting the ammonia in the ammonia-containing gas with acid to form an ammonium salt. The acid scrubber comprises a scrubbed air outlet 32 in fluid communication with a hot air inlet 20 of the ammonia stripper, such that scrubbed air which is discharged from the acid scrubber may be recycled for use in the ammonia stripper. Also described is a system and method for removing ammonia from an ammonia-containing liquid, wherein the system comprises a cold-water scrubber for removing ammonia from the ammonia-containing gas discharged from the ammonia stripper.
Abstract: An ambient water condenser system is described having a condensation chamber which at least partially contains or surrounds a fluid reservoir which contains a volume or mass of an aqueous hygroscopic solution for condensing water from ambient air and a distillation process for extracting the water from the solution. The fluid reservoir has a heat source, a lower porous hydrophobic membrane, and an upper porous hydrophobic membrane. The heat source causes the hygroscopic solution near the top of reservoir to have a higher temperature which causes it to have a higher water vapor pressure, whereby the water vapor passing through the upper porous hydrophobic membrane and into the condensation chamber condenses into liquid water.
Abstract: The invention relates to chemical-based methods and products for mitigating the impact of an oil spill, that act via mechanisms which include reducing adhesiveness, herding, thickening and gelling. N-fatty acid amino acid (FA-AA) conjugates display oil-herding behavior when formulated as a salt, or the free acid in water-miscible organic solvents. Various salts of FA-AA conjugates are water soluble and can herd oils and increase the thickness of the oil layer. Replacement of the acid group of fatty acid ?-amino acid conjugates with other groups that act as hydrogen bond donors and acceptors results in potent phase selective organo gellants. The oil thickeners or gellants include can be prepared from biobased feedstocks, have low toxicity, high capacity for oil and reduction of the need to use an organic solvent to apply the thickener or gellant to an oil and water mixture in order to gel the oil phase.
