The invention is a method for liquid, gaseous or supercritical phase chromatography which involves circulating, on a chromatograph (6) containing a stationary phase, a load (1) comprising components to be separated entrained by a carrier fluid (2), said method being characterized in that it involves: (a) obtaining, at the outlet of the chromatograph, a plurality of chromatographic fractions (3, 4) comprising at least one component of the load and the carrier fluid in a first fluid phase, (b) imposing a change of state on at least one of said chromatographic fractions (3, 4) so as to obtain at least one fraction of purified carrier fluid in a second fluid phase different from the first fluid phase by separating said carrier fluid from the component of the load, (c) imposing a change of state in a reverse direction to that of step (b) on at least one fraction of purified carrier fluid obtained in step (b) so as to obtain at least one fraction of purified carrier fluid in a third fluid phase different to the second fluid phase, and in that it involves coupling the change-of-state energies from the first fluid phase to the second fluid phase and from the second fluid phase to the third fluid phase of the same or of another fraction of purified carrier fluid, said coupling comprising a transfer of heat using a heat pump.

Apparatuses for removal of solids from water comprising a heater for heating an immiscible liquid (IL), a humidifier having porous sheets allowing direct contact between the IL and water, thereby separating the solids by evaporating the water into cool dry air flowing past the porous sheets, and a dehumidifier comprising porous sheets that allow direct contact between the cool IL and hot moist air flowing past the porous sheets, thereby condensing fresh water from the moist air. Also disclosed are methods for removal of solids from water by heating an IL, distributing the IL to porous sheets in a humidifier, distributing water with dissolved solids to the porous sheets, separating the solids from the water by evaporating the water into dry air flowing past the porous sheets, and condensing fresh water by flowing the moist air past porous sheets in a dehumidifier having cool IL distributed to the porous sheets.

A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu—Cl Cycle. Non-pure water is used as the feedstock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feedstock of industrial processes. The direct usage of this water can significantly reduce water supply costs.

A process for separating distillate and waste from a water stream comprising: spraying the water stream together with compressed steam through one or more dual phase nozzles down into one or more vertical tubes contained in a shell and tube heat exchanger; evaporating water condensing the distillate; and ejecting the waste.

A system captures carbon dioxide from a flue gas of a power generation facility by using cold heat of liquefied natural gas and utilizes the captured carbon dioxide for mining natural gas, using heat of the flue gas to regasify the LNG. Solidified dry ice is captured from gaseous carbon dioxide contained in the flue gas, and the captured dry ice is used as filler when mining natural gas. The system includes a mining facility, a vehicle to transport LNG liquefied by the mining facility; and a facility for regasifying the transported LNG and capturing dry ice from the carbon dioxide. In the regasification and capture facility, the flue gas exchanges heat with the LNG, thereby regasifying the LNG at an increased temperature and capturing the dry ice from the carbon dioxide. The captured dry ice is transported to the mining facility, which uses it for mining the natural gas.

A desalination system includes a distillation unit to which a fluid to be desalinated is provided and through which a heat transfer fluid flows, and a solar concentration unit configured to heat the heat transfer fluid. The solar concentration unit includes an array of linear Fresnel reflectors, each linear Fresnel reflector of the array of linear Fresnel reflectors rotating about a respective axis, a receiver configured for absorption of light redirected by the array of linear Fresnel reflectors, the receiver comprising tubing through which the heat transfer fluid flows, and a frame supporting and positioning the receiver relative to the array of linear Fresnel reflectors. The frame defines a track along which the receiver is movable to adjust a relative position of the receiver along the respective axis of each linear Fresnel reflector of the array of linear Fresnel reflectors.
