A system and method for extracting essential oils is provided. One embodiment comprises an extractor assembly with an extractor cover, an extractor container, and an extractor assembly base, wherein the extractor container is secured between the extractor cover and the extractor assembly base during an extraction process; a bowl cover assembly with a collection bowl, and a bowl cover assembly base, wherein the collection bowl is secured between the extractor assembly base and the bowl cover assembly base during the extraction process; and a canister compression holder assembly, wherein a cannister containing a solvent is secured within the canister compression holder assembly during the extraction process. A solvent that is released from the cannister passes into the extractor container that contains matter that is to have essential oils extracted therefrom. The extracted oils exits the extractor assembly base into the collection bowl that collects the solvent with the essential oils.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

An air thermal conditioning system, for at least one of heating air and cooling air, which includes a cross-flow heat exchanger array. The cross-flow heat exchanger array includes a plurality of planar membrane heat exchangers disposed in parallel with a space separating adjacent planar membrane heat exchangers. Each of the planar membrane heat exchangers include a first sheet; a second sheet coupled to the first sheet; and at least one fluid chamber defined by the first and second sheets, with the at least one fluid chamber extending between first and second ends of the planar membrane heat exchangers and opening to a first and second port at the first and second ends respectively.

Embodiments may include methods and systems for purifying a product and recovering a solvent. In a first stage, a raw feed comprising an initial solvent fraction and an initial product fraction may be heated using a first heat exchanger, and an intermediate vapor fraction of the initial solvent fraction may be vaporized using a first vapor liquid separator to yield an intermediate product comprising intermediate solvent and intermediate product fractions. The intermediate vapor fraction may be condensed to a first solvent condensate using a first condenser. In a second stage, the intermediate product may be heated using a second heat exchanger, and a final vapor fraction of the intermediate solvent fraction may be vaporized using a second vapor liquid separator to yield a purified product comprising final solvent and final product fractions. The final vapor fraction may be condensed to a second solvent condensate using a second condenser.

A distillation assembly which, with the aid of solar energy, continuously evaporates a feed liquor. The distillation assembly includes a container which contains the feed liquor, a container in which the distillate is collected, these containers being in thermal contact, and a compressor. The compressor compresses the vapor which is produced by boiling the feed liquor using the concentration of solar energy and/or using negative pressure, into the distillate container such that the vapor condenses there, and the evaporation enthalpy and thermal energy is returned to the feed liquor by the thermal contact.

Apparatus and methods are related to treating waste water containing ammonium salts, which contains NH.sub.4.sup.+, SO.sub.4.sup.2, Cl.sup., and Na.sup.+. In such a method, the pH value of the waste water to be treated is adjusted to a specific range in advance; sodium sulfate crystal and relatively concentrated ammonia are obtained by first evaporation, and then sodium chloride crystal and relatively dilute ammonia is obtained by second evaporation; alternatively, sodium chloride crystal and relatively concentrated ammonia is obtained by third evaporation, and then sodium sulfate crystal and relatively dilute ammonia are obtained by fourth evaporation. Ammonia, sodium sulfate, and sodium chloride from the waste water are recovered so that the resources in the waste water can be reused.
