Vapor flow-diverting devices that re-direct upwardly flowing vapor, for example, in a downward direction across condenser tubes disposed in the upper or top section of a vapor-liquid contacting apparatus, are described. These devices are particularly beneficial in tubular condensers within distillation columns and may be used in combination with other associated equipment (e.g., a deflector plate and divider plate) as well as in combination with the tube surface enhancements to improve the heat transfer coefficient.

The disclosure provides a blowpipe assembly for removing at intervals liquid, such as pulled from a knockout assembly, having a three-way electrically operated valve, tuning fork level sensors, and access to the blowpipe interior.

A remedial pollution control system for treating volatile organic compounds that may include a vapor concentrator connected to a line that is laden with volatile organic compounds, the concentrator has an organic condensate output line and a vapor output line; a mixing chamber adapted to receive air provided from an air supply line, combustible fuel from an alternate fuel supply line, and a vapor stream from the vapor output line to produce a mixed fuel supplied to an internal combustion engine, a control mixing system with a controller for producing a proper air to fuel ratio in the mixed fuel supply, and power generated to operate other devices used to more efficiently abate volatile organic compounds and reduce greenhouse gas emissions.

A methane destruction apparatus for capturing and converting fugitive methane gas emissions into carbon dioxide and water comprises a methane-capturing module for capturing the fugitive methane gas emissions and a methane conversion module for receiving captured methane from the methane-capturing module. The methane-capturing module includes a fugitive methane gas emission intake connected to an emissions line having a backpressure equal to 1 to 3 inches of water (249 to 746 Pa), a natural gas feed for feeding natural gas into the methane-capturing module, may include a relief vent for preventing overpressure within the methane-capturing module and a drain for draining liquids that have condensed within the methane-capturing module. The methane conversion module includes a conversion pad for catalytically converting the captured methane into carbon dioxide and water, a water vapour opening for outputting the water and a carbon dioxide opening for outputting the carbon dioxide.

A potable water making apparatus includes a thermoelectrical cooling plate, air intake, and a separator. The thermoelectrical cooling plate is operable with electrical power to form a cool surface. The air intake guides the air from a surrounding across an area of the cooling plate, and the separator drives condensation from the cool surface to a reservoir.

A distillation probe includes a conduit having a central axis. In addition, the distillation probe includes a baffle assembly disposed in the conduit. The baffle assembly includes a plurality of axially-spaced baffles positioned one-above-the-other in a stack within the conduit. Each baffle has a central axis and a radially outer surface. Each baffle includes a first recess disposed along the radially outer surface of the baffle and extending axially through the baffle. Further, each baffle includes a plurality of cooling conduits mounted to the conduit and positioned radially adjacent the conduit. The cooling conduits are configured to cool the conduit and the baffles.

Plant and process for separation of sulfur-containing components, H.sub.2S, COS and mercaptans from methanol which is used as absorbent within the Rectisol process by hot regeneration of the methanol laden in the absorption and an additional step for separation of the mercaptans from the methanol by stripping.

Disclosed is a plant for the production of urea. The plant comprises conventional sections for synthesis and recovery, for evaporation and condensation, for urea finishing, and for dust scrubbing. According to the invention, an additional evaporation and condensation loop is introduced from and to the dust scrubbing section. This loop results in a more favorable energy consumption of the plant.

A method of generating oxygen and at least one of hydrogen or ammonia includes receiving ambient air containing moisture, collecting liquid water from the ambient air, receiving, by a water electrolyzer, the collected liquid water and electricity from an electrical source, and performing an electrolysis process by the water electrolyzer to thereby generate the oxygen and the at least one of hydrogen or ammonia from the received liquid water and electricity.

A method is disclosed for recovering a useful gas from a gas mixture including a useful gas and at least one secondary gas. The gas mixture is first compressed and transferred into a pressure vessel where cooling occurs. Then, from the pressure vessel, a secondary-gas containing gas phase is removed and condensed useful gas is transferred into a purification vessel. In the purification vessel, the condensed useful gas is then purified. A plant is disclosed for recovering a useful gas from a gas mixture. Finally, the use of a plant for carrying out a method for recovering a useful gas from a gas mixture is disclosed.
