A closed couplable extractor has a plurality of tubes that function as extracting chamber tubes and/or solution receiver tubes where the tubes are fixed or reversibly connected. Tubes from two closed couplable extractors can be placed in proximal contact to exchange heat between tubes in coupled extractors. Adjacent pairs of tubes in an extractor are connected by at least two transfer conduits, allowing positioning the pair of tubes a higher and lower tubes for distilling vapor through vapor conduits to higher tubes and draining extract solution through solution conduits to lower tubes. The extractor has at least one valve to isolate the extractor from ambient and optional valves to isolate tubes within the extractor. Valves can be couplable valves that permit one or more tubes to enter and exit the system without removal of air or loss of liquid to the environment during these steps while performing extraction processes.

A water separator for use in an environmental control system of an aircraft including an outer housing having an upstream end, a downstream end, and a central longitudinal axis. 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.

Disclosed is a tube-sheet suitable for holding a tube bundle of a shell-and tube heat exchanger adapted to withstand the pressure at the shell side. Said sheet comprises a carbon steel plate provided with a plurality of holes. Both surfaces of the tube-sheet are covered by a weld overlay, said weld overlay comprising a layer of duplex stainless steel on at least one surface thereof. The sleeves are fixed to the tube-sheet by means of a weld connection to either weld overlay. Hereby at least one such connection is on the inside of the holes.

Apparatus for obtaining potable water from an impure water source comprising a container having at least a first end wall, a second end wall, a first sidewall, a second sidewall and a top wall; a volume of the impure water; a heater device for heating the volume of impure water to produce gaseous water molecules; a condensing system located inside the container for providing water condensate from the water molecules; an outlet for providing a flow of potable water from the water condensate; and a collection device for collecting the water condensate and moving the water condensate towards the outlet.
