Embodiments of the present disclosure can include a system for harvesting salt and generating distilled water from at least one of a produced water and salt water, comprising. A direct steam generator (DSG) can be configured to generate saturated steam and combustion exhaust constituents from the at least one of the produced water and salt water. A separation system can be configured to separate the salt from at least one of the saturated steam and combustion exhaust constituents in brine form or solid form. An expansion turbine can be configured to recover energy from the steam and combustion exhaust constituents.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

Disclosed is a shell-and-tube heat exchanger type with a tube bundle and has a redistribution chamber connected to tubes of the tube bundle and to a duct. The duct extends between the redistribution chamber and the shell.

A process and apparatus cool and remove catalyst from a hot vaporous reactor effluent stream by feeding the hot vaporous reactor effluent stream comprising catalyst and a first quench liquid stream to a first quench chamber. The hot vaporous reactor effluent stream is directly contacted with the first quench liquid stream to cool the hot reactor effluent stream and wash catalyst therefrom into the first quench liquid stream. The first quench liquid stream and the vaporous reactor effluent stream are passed together through a bed while disengaging catalyst from the vaporous reactor effluent stream and transferring catalyst into the first quench liquid stream.

A mist extraction system is provided that includes a plenum box having an inlet configured to be coupled in fluid communication with a machine tool enclosure. A blower is coupled in fluid communication with the plenum box and is configured to draw air into the plenum box from the machine tool enclosure via the inlet of the plenum box and exhaust the air back into the machine tool enclosure via an outlet of the blower. A baffle plate is arranged in the plenum box to redirect the air drawn into the plenum box through the inlet of the plenum box and a filter panel is arranged in the plenum box to filter the air redirected by the baffle plate prior to the air entering the blower. A collector arranged to collect mist from the air condensed on the baffle plate and the filter panel.

In a system for performing a multi-step process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step of the process provides a low-temperature, robust process for dehydrating and decarboxylating the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. An important by-product of the dehydration/decarboxylation is a terpene-rich distillate. By doing the terpene capture under vacuum, distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids.

A method and system for rapidly preparing lithium carbonate or concentrated brine using high-temperature steam. The method comprises the steps of: feeding brine into a reactor, heating the brine with high-temperature steam above 200° C. while simultaneously discharging steam produced in the reactor, cooling and condensing the discharged steam in a condenser and collecting the condensate, and stopping the high-temperature steam after the brine is concentrated to a predetermined concentration or after a sufficient amount of lithium carbonate is collected. The system comprises: a reactor provided with a brine inlet, a steam outlet connected to a condenser, a product outlet, and a plurality of steam pipes. The method concerns the direct heating of brine using high-temperature steam, which is effective and efficient, and also produces fresh water. The heating is uniform and rapid, and does not require jackets, heat exchange tubes, mixers and vacuum pumps, vastly simplifying the system.

A method for removing moisture from moist air in an appliance, such as a treating chamber of a dishwasher, wherein a drying system includes a condensing system and heat exchange systems that enhance condensation with both ambient air and cold water. The method includes storing cold water for use during a cycle of operation; recirculating the moist air in the treating chamber through a condenser; during the recirculating, flowing ambient air over the condenser; and during the recirculating and after the flowing ambient air, flowing the cold water over the condenser.

A CO.sub.2 extraction process for cannabis sativa that uses liquid CO.sub.2 in combination with co-solvent admixtures to purify cannabis botanicals in high yield and purity. The extraction process allows for multiple extractions, or washes, to be performed with the same solvent CO.sub.2, which may be seamlessly recycled and purified between subsequent extraction cycles. A variety of in-line filtration vessels, pumps, vacuums, and controllable valves are used to yield a pure product while allowing a high level of user control over the process.
