The disclosure includes a water system that includes a feed water heat exchanger including a feed water heat exchanger above a water collection tank and a feed water heat exchanger/steam generator connected to the feed water heat exchanger. The feed water heat exchanger/steam generator includes a heat exchanger, coils, boiler burners, and emissions control. The water system includes a brine/waste water feed water heat exchanger positioned within brine/waste water tank enclosure, which includes a brine/waste water tank that is in fluidic connection with the feed water heat exchanger/steam generator. The water system includes a preheater in fluidic connection with the brine/waste water feed water heat exchanger, and a post-preheater heat exchanger enclosure including a post-preheater heat exchanger, post-preheater coils, post-preheater burner and post-preheater emissions control, the post-preheater heat exchanger in fluidic connection with the pre-heater. The water system includes a vapor removal device in fluidic connection with the post-preheater heat exchanger.

A debinder provides for debinding printed green parts in an additive manufacturing system. The debinder can include a storage chamber, a process chamber, a distill chamber, a waste chamber, and a condenser. The storage chamber stores a liquid solvent for debinding the green part. The process chamber debinds the green part using a volume of the liquid solvent transferred from the storage chamber. The distill chamber collects a solution drained from the process chamber and produces a solvent vapor from the solution. The condenser condenses the solvent vapor to the liquid solvent and transfer the liquid solvent to the storage chamber. The waste chamber collects a waste component of the solution.

A short-path distillation apparatus and method of operation are described. An example short-path distillation apparatus includes a double-walled bulb-shaped condensing head. The double wall forms a coolant chamber that substantially envelopes an inner condensate chamber. Coolant is introduced into and removed from the coolant chamber via ports in the outer wall of the head. Condensate in gaseous form is introduced into the condensate chamber where it comes in contact with and condenses as distillate upon the cold inner surface of the condensate chamber. Condensed distillate travels down the inner surface of the condensate chamber and then into a distillate outlet conduit that transports the condensed distillate to a collection vessel.

Provided herein are integrated distillation apparatuses configured as stand-alone fully integrated systems having a reduced footprint. Integrated distillation apparatuses can have a rotary evaporator, a condenser, and an integrated refrigeration system or chiller, as well as an integrated water bath and vacuum pump, all of which can be integrated into a central frame and/or housing assembly. Integrated distillation apparatuses can be configured such that the rotary evaporator is movably attached to a frame structure and configured to be vertically translatable in position, whereas the condenser can be affixed to the structure by an arm extending from the structure and adjacent to the rotary evaporator, and wherein the refrigeration system can be in fluid communication with the condenser.

An arrangement for closing a container, in particular a flask, for determining evaporation properties of a liquid in the flask according to at least one standardized test. The arrangement has at least one temperature measurement system, a sensor, a closing element adapted for contacting a surface of an opening in the container for closing the container and having a through-opening through which a portion of the temperature measurement sensor is guided such that a lower end of the sensor is arranged within the container. The arrangement further includes a mechanism for adjusting a position of the lower end of the sensor along a longitudinal direction of the temperature measurement sensor.

The present disclosure relates to water purification. The teachings thereof may be embodied in processes for removing contaminants from contaminated water. An example process may include: boiling or evaporating a contaminated water to distill the contaminated water; removing a vapor stream from the boiling or evaporating contaminated water; delivering the vapor stream to an oxidation unit; removing additional contaminants from the vapor stream in the oxidation unit; and discharging a purified water stream from the oxidation unit.
