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.

The present disclosure relates generally processes and systems for converting a C2-C7 light alkanes feed to liquid transportation fuels or value-added chemicals. The feed is contacted with an aromatization catalyst at a temperature and pressure that selectively converts C4 and larger alkanes to an intermediate product comprising monocyclic aromatics and olefins. Following separation of the aromatics and C5+ hydrocarbons from the intermediate product, unconverted C2-C3 alkanes are thermally-cracked to produce olefins that are subsequently oligomerized to produce a liquid transportation fuel blend stock or value-added chemicals.

Systems and methods for solvent-free direct extraction of target compounds from compositions of matter are disclosed herein. The disclosed systems and methods use low pressure to reduce the evaporation temperature of target compounds without affecting the chemical integrity thereof. Target compounds are extracted from the composition of matter in an evacuation chamber and then collected using a capture system. Target compounds may be drawn from the evacuation chamber into the capture system using a carrier gas to facilitate transport of the targeted compounds in the vapor phase. A processed vapor stream may be transported from the capture system back into the evacuation chamber using a recirculation system that includes a blower. The disclosed systems and methods may be used, for example, to extract target compounds from plant matter such as fresh or dried cannabis and hemp, lavender, rosemary, lilac, or other suitable plant matter containing desirable compounds for extraction.

Devices, systems, and methods for liquefied natural gas production facilities are disclosed herein. A liquefied natural gas (LNG) production facility includes a liquefaction unit and a gas turbine. The liquefaction unit condenses natural gas vapor into liquefied natural gas. The LNG production facility further includes at least one post-combustion capture unit that captures a carbon dioxide (CO2)-rich stream from a flue gas stream of the gas turbine. The LNG production facility also includes a sequestration compression unit that compresses at least one CO2-rich stream from the at least one post-combustion capture unit.

An apparatus for condensing water and producing electricity. In one embodiment, the apparatus may comprise a plurality of fabricated tubes, wherein the tubes may be filled with and enclose hydrogen, helium, or combinations thereof, and wherein the tubes may be bonded together lengthwise in a circular assembly to provide a cylindrical structure comprising a central bore. Further, the apparatus may comprise and a ground structure, wherein a lower portion of the cylindrical structure may be tethered to the ground structure.

An atmospheric water generation system absorbs water from an atmospheric air stream into a desiccant flowing along a flow path of a closed desiccant circulation loop. To ensure that the desiccant remains within the closed desiccant circulation loop, the atmospheric water generation system encompasses a membrane-based water extraction device that the desiccant flows through. The desiccant flows through the membrane-based water extraction device on a first side of a membrane, and the membrane separates the desiccant from a water-collection flow. Water absorbed into the desiccant passes from the desiccant, through the porous membrane, and into the water-collection flow, at least in part due to differences in temperature and/or pressure characteristics of the water flow and the desiccant flow. Water collected within the water-collection flow is directed to a storage tank for usage.

The disclosed systems and methods use low pressure to reduce the evaporation temperature of target compounds without affecting the chemical integrity thereof. Target compounds are extracted from the plant matter in an evacuation chamber, and the extracted target compounds are then collected using a cooling system. Target compounds may be drawn from the evacuation chamber into the cooling system using a carrier gas to facilitate transport of the targeted compounds in the vapor phase. The evaporated target compounds may, for example, be drawn into the cooling system using a recirculation system that includes a blower.

Techniques in the disclosure use non-wetting or wetting surfaces to promote or hinder separation of gas from solution in a liquid. The systems and processes promote bubble nucleation and/or promote separation of a gas or gases from a liquid using non-wetting surfaces. Also, the systems and processes suppress bubble nucleation in order to create supersaturated solutions of gas or gases in a liquid by using wetting surfaces.

Method and apparatus for synthesizing compounds by a low temperature plasma dual-electric field aided gas phase reaction are provided. The method utilizes two different electrode corona discharge fields in a plasma aided reactor to form a plasma dual-electric field, using electric energy to convert gas into gas molecules, atoms, ions and/or free radicals, and then reforming and reducing to obtain organic compounds such as aliphatic hydrocarbons, higher carbon ethers, higher carbon alcohols, higher carbon esters, lower carbon alcohols, and the like; also inorganic compounds such as N.sub.2, O.sub.2, H.sub.2SO.sub.4, NH.sub.3, and the like. The apparatus includes a reactor having a plasma region of two different corona discharge fields, wherein an alternating current corona discharge field or a positive corona discharge field is set in the first electric field, and a negative corona discharge field is set in the second electric field.
