Methods and apparatus for recovering heavy oil from subterranean reservoirs. A steam-utilizing heavy oil recovery process may be used to recover the heavy oil while employing a steam-solvent mixture. The solvent may be a tailored hydrocarbon solvent obtained from a precursor mixture of hydrocarbon compounds from which light end hydrocarbon compounds have been removed.

Provided is a catalyst article for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The catalyst article has a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia.

An atmospheric water vapor extraction device includes a supply of hygroscopic solution contained within reservoir which includes an evaporation chamber, a condensation chamber, a water latent solution within conduit, a solution container, and water depleted solution within a conduit. The conduits extend into the container to a level below the solution level within the container to prevent passage of air into the conduits. The water extraction device further includes potable water collection conduit and potable water container. The water collection conduit connects the condensation chamber to water container. The conduit extend into container to a level below the level of water within the container to prevent passage of air into the conduit and thereby maintain a level of vacuum within chamber that is representative of the weight of the water column within conduit and the vapor pressure of the water at the top.

Systems and methods for heat exchange and water generation are disclosed. Water generation systems described herein include a housing with a front surface comprising a solar thermal portion to convert solar radiation into heat and a solar electric portion to convert solar radiation into electrical energy. A sorption unit or layer captures water vapor from a process gas during a sorption mode and releases water vapor to a regeneration fluid heated by the solar thermal portion during a desorption mode. A heat exchange assembly includes a condenser to condense water from the regeneration fluid and a recuperator to transfer heat between fluid flow segments. Methods include directing a regeneration fluid along a flow path through a solar thermal portion, capturing and releasing water vapor via a sorption unit or layer, transferring heat using a recuperator, directing cooling fluid through a condenser, and condensing water vapor from the regeneration fluid.

A heat driven osmosis water and power generator consists of dilute hygroscopic solution flow loop, an air humidity exchanger, a condensation solution circulation pump, a pressure retarded osmosis exchanger, a pressure exchanger, an evaporation chamber, a recuperative heat exchanger, a concentrated solution circulation pump, a solution pressure differential turbine generator, a freshwater power turbine, a concentrated hygroscopic solution flow loop and condensed water reservoir. The pump circulates low concentration, dilute, hygroscopic solution between air humidity exchanger and osmosis exchanger. Moisture is absorbed into low concentration hygroscopic solution from air circulation through humidity exchanger. As solution circulates through osmosis exchanger, moisture is extracted through osmosis membrane by concentrated hygroscopic solution. Concentrated hygroscopic solution circulation pump circulates high concentration solution between pressure retarded osmosis exchanger and vaporization chamber. Solution flowing to and from vaporization chamber is maintained at a lower pressure than fluid circulating through osmosis exchanger.

A plurality of vanes are arranged within the outer housing and are spaced about the central longitudinal axis. A plurality of flow channels are formed between the plurality of vanes and the outer housing. The plurality of flow channels have a spiral-like configuration about the central longitudinal axis. At least one ring vane is arranged within the outer housing and extends parallel to the longitudinal axis.

Systems and methods are provided for a system for extracting volatile components from produce. In an embodiment, a conveying mechanism is configured to transit produce from a first point to a second point, where a peel of the produce is penetrated during said transit such that a portion of volatile components in the produce peel are released from the peel as a vapor. A hood is positioned over the conveying mechanism for capturing the vapor, where the system is configured to extract at least a portion of the volatile components of the vapor captured via the hood.

A continuous solution polymerization process may include producing a product including a polymer through a polymerization process in a reactor; separating the product into a first solution including the polymer and a second solution including the polymer in the liquid-liquid separator; supplying the first solution to a devolatilizer and supplying the second solution to a solid-liquid separator (S/L separator); separating the second solution into a vapor including the polymer and a liquid-state polymer in the devolatilizer; separating the second solution and the vapor including the polymer into a solvent capable of being introduced into the reactor and a solid including the polymer in the solid-liquid separator (S/L separator); and introducing and recirculating the solvent capable of being introduced into the reactor into the reactor.
