The invention relates to an atmospheric water generator that includes an absorption heat transformer (AHT) designed as a heat pump that is able to extract heat even from waste heat sources at or below ambient temperatures, with an evaporator working at a favourable design temperature (preferably between 2° C. and 15° C.) for chilled water supply to a cold coil that extracts atmospheric water from ambient air. The AHT employs a pseudo-isobaric temperature glide bubble reactor that contains a suitable binary liquid-vapour mixture in a density separation distillation environment, powered by a vapour absorption process.

Provided herein are methods and systems for treating a tail gas of a Claus process to remove sulfur-containing compounds. The method includes combusting a tail gas of a Claus process in an excess of oxygen gas to yield a thermal oxidizer effluent. The thermal oxidizer effluent includes sulfur dioxide, water vapor, and oxygen. The effluent is routed to a quench tower and contacted with a dilute aqueous acid quench stream to yield sulfurous acid, hydrated sulfur dioxide, or both. The sulfurous acid or hydrated sulfur dioxide is oxidized with the excess oxygen from the thermal oxidizer effluent to yield sulfuric acid.

A moisture trap for removing liquid from a fluid drawn from a tissue site treated with reduced pressure and systems and methods for using the same are described. The moisture trap may include a barrier adapted to be fluidly coupled to and define an indirect fluid path between a fluid reservoir and a reduced-pressure source. The barrier may have a hydrophilic surface. The moisture trap also may include a sump adapted to receive condensation from the barrier.

System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.

Device for extracting water from humid ambient air, the device including a conduit in which successively is incorporated: a compressor to compress the humid ambient air into compressed ambient air, a first condenser to dry the compressed ambient air into dry compressed air, an expansion valve or expander for expanding the dry compressed air into dry expanded air and a second condenser. The first condenser is further configured to direct the wet ambient air through it as coolant for extracting water from the compressed ambient air in a first stage via an outlet or the like. The second condenser is configured to direct the dry expanded air through it as coolant for extracting the water from the humid ambient air in a second stage by means of an outlet or the like.

Provided are systems and related methods for processing organic polymeric feed materials—such as plastics—to form pyrolysis oil. The disclosed systems can be operated in a continuous manner and utilize novel liquid-solid separation techniques integrated with a novel condensing approach so as to operate in a product-efficient and an energy-efficient manner.

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.

A thermal cracking treatment train, comprising: a rotatable kiln reactor; the rotatable kiln reactor being configured to receive a polymeric feed material, the reactor defining at least one interior wall that bounds an interior volume of the reactor, the interior volume defining an entrance and an exit along a direction of feed material travel, the rotatable kiln reactor comprising a section that comprises one or more sweeping features configured to sweep, with rotation of the kiln, a portion of the at least one interior wall, the kiln comprising a section that comprises one or more lifter features extending from the at least one interior wall and configured to, with rotation of the kiln, encourage material disposed on the one or more features to fall into the interior volume of the interior kiln; a combustor configured to provide a heated gas to the rotatable kiln reactor; and a devolatilization train.

A water production system with a thermal separation device that defines a cold region and a hot region, a fluid-air heat exchanger located remotely from the thermal separation device and exposed to air, and a fluid circulation loop that thermally connects the cold region of the thermal separation device to the fluid-air heat exchanger so as to cool the fluid-air heat exchanger and condense water from ambient air to produce water pure enough so that with further treatment it can be made potable. Also disclosed are filtration and dispensing features that are appropriate for a potable water supply.

Method of improving the efficiency of polyolefin production comprising: performing a reaction to yield (1) a product stream comprising a polyolefin, and (2) a purge stream, wherein the purge stream comprises unreacted monomers, inert impurities and saturated co-monomers; compressing the purge stream in a first stage compressor to create a first compressed stream; cooling the stream first compressed stream in a cooler to create a cooled stream; directing the cooled stream to a first drum, to create a waste liquid stream and a first drum stream; removing the waste liquid stream from the first drum; compressing the first drum stream in a second stage compressor to create a second compressed stream; condensing the second compressed stream to produce a condensed stream; processing the condensed stream in a second drum to produce a second drum gas stream and a second drum liquid stream; and, sending at least a portion of the second drum liquid stream to a polyolefin reactor.
