Desalination

Patent Number: 8444830
Publication Date: 2013-05-21
Inventor:

A desalination process including heating brine in a preheating chamber and transferring the brine to a rotary kiln to be sprayed against the wall structure of the rotary kiln to boil to steam and a residue of salt/impurities, the exiting steam being pressurized in a compressor and passed to an externally powered heater to be heated and then fed to a hollow wall structure of the rotating kiln in which the steam condenses to pure water to be transferred to the preheating chamber to preheat ...

Systems, processes and methodologies for producing clean water

Patent Number: 8444829
Publication Date: 2013-05-21
Inventors: ;

Improved methods for carrier-gas humidification/dehumidification [HDH] or dewvaporization enable production of clean water, derived in part from models generated and tested with produced water from the oil and gas industries, which likewise address industrial waste water remediation and generally facilitate the time and cost efficient disposal of waste waters from a plurality of industries ranging from food, wine, and beverage production to novel enhanced efficiencies within the oil and gas ...

Method for concentrating nitrogen isotope

Patent Number: 8440058
Publication Date: 2013-05-14
Inventor:

Method for concentrating nitrogen isotope to obtain a final product nitrogen, in which the stable nitrogen isotope, ¹⁵N, is concentrated, by low-temperature distillation of raw material nitrogen containing trace amounts of oxygen and argon using a plurality of distillation columns in a cascade arrangement. An argon-oxygen mixture is discharged from the bottom of the final column and ¹⁵N-concentrated nitrogen is extracted from a lower intermediate point of the final ...

Small-scale method and apparatus for separating mixtures

Patent Number: 8435387
Publication Date: 2013-05-07
Inventors: ; ;

The present invention generally relates to the small-scale separation of a mixture of two or more components with different boiling points into enriched fractions. In some embodiments, a first and second fluid (e.g., a liquid and a gas, a liquid and a liquid, etc.) are passed through a channel. The first fluid may include at least two components, each with a unique boiling point. Upon contacting the first and second fluids within the channel, at least a portion of the most volatile of the ...
