A system and method that uses a high-temperature condenser to collect magnesium produced by thermal reduction, electrolysis, or distillation. The condenser is a common heat exchanger design (shell/tube, plate/plate, etc.) and uses a heat transfer fluid to cool and condense magnesium gas, e.g., to 200-900° C. under vacuum or pressure conditions. Solid or liquid magnesium is collected in the condenser along with any by-products or impurities at a purity greater than 35 wt-% Mg. Magnesium is subsequently liberated from the condenser by raising the temperature of the system, lowering the pressure, or both, to induce a phase change in the metal, such as melting or distillation, for further purification to, e.g., >90 wt-% Mg.

An apparatus, system, and method for the extraction of water molecules from the air includes a combination of electrical mechanisms and materials engineering. With the help of hydrophobic and hydrophilic materials on an array of thermally conductive and electrically insulated materials, the extraction of water from the air is significantly increased. A combination of hydrophobic and hydrophilic materials and an electric field gradient moves the water molecules towards the collection system thus speeding up the water formation process. This also inhibits the re evaporation of the water droplets.

The present disclosure provides processes and systems for heat integration in ethanol production. In one embodiment, a feed mixture is distilled with one or more distillation units to remove at least a portion of the water, and form a distillation unit bottom stream, a vaporous overhead stream, and a fusel oil stream. Molecular sieve units are regenerated by vacuum or a combination of vacuum and optionally a portion of the product stream to form one or more regenerate streams. A feed tank is configured to receive at least one selected from a condensed portion of the regenerate streams and a portion of a vaporous depressure stream, to form a feed stream. The energy contained in the depressure vapor is recovered by the depressure vapor contacting the feed tank and heating up at least one stream forwarded into the feed tank.

The process of producing concentrated maple sap can include concentrating the maple sap using membrane filtration to a sugar content of approximately 30° Brix, circulating the maple through a maple sap passage of a membrane, wherein the membrane contains the maple sap in a vacuum cavity, and evaporating the water from the maple sap across the membrane into the cavity. The concentrated maple sap having a sugar content above 50° Brix.

Disclosed is a removable containment device for a rotary evaporator, comprising: a first end (12) for sealed connection to a rotation shaft (3) of the rotary evaporator (1); a second end (13) for sealed connection to a container (2) for receiving a mixture to be evaporated; and a body (11) in fluid connection with the first and second sealed connection ends (12, 13) comprising a valve system (14) for the selective passage between the first and second ends (12, 13) of the evaporating constituent of the mixture to be evaporated.

A rotary evaporator for accurately and quantitatively recovering multiple solvents or concentrating multiple samples at once is provided. At least two distillation flasks are included. The distillation flasks are connected in sequence and rotated along the same axis. A bracket is disposed at the lower part between the distillation flasks for support. Instead of one rotation axis, at least two axes are included. Each rotation axis is provided with at least one distillation flask. The number of condensers and the number of collecting flasks increase correspondingly with the number of distillation flasks. If the number of distillation flasks on one rotation axis is greater than 1, a connector is disposed between the condenser and a transmitter. The collecting flask can be changed into a collector with the function of accurately quantitating and discharging distillates. Each distillation flask may be connected to a concentrated liquid quantitative assembly.

A method, device and a system for extracting oil from a paste of oily fruit by exposing the oily fruit paste to vacuum.

This invention was designed to condense, separate and collect volatile compounds from the vapor steam as they exit the dehydrator. Bulk condensate is allowed to accumulate and separate in a separator vessel under vacuum. The undesirable water phase condensate is periodically drained into a water vessel, which is also held under vacuum instead of atmospheric pressure to avoid agitation and mixing of the contents of the separator vessel arising from purging the separator vessel to atmosphere. The separated and desirable oily condensates can then be easily recovered from the separator vessel.
