A process to catalytically transform natural gas liquid (NGL) into higher molecular weight hydrocarbons includes providing an NGL stream, catalytically dehydrogenating at least a portion of the NGL stream components to their corresponding alkene derivatives, catalytically oligomerizing at least a portion of the alkenes to higher molecular weight hydrocarbons and recovering the higher molecular weight hydrocarbons. The NGL stream can be extracted from a gas stream such as a gas stream coming from shale formations. The higher molecular weight hydrocarbons can be hydrocarbons that are liquid at ambient temperature and ambient pressure.

Natural gas liquids upgrading process: two-step catalytic process for alkane dehydrogenation and oligomerization

Systems and processes for quenching a high-temperature, above atmospheric pressure feed to a lower temperature without the need of any quenching fluid and with the additional benefit of coproducing electric power. The systems and processes provided here result in a simpler quenching process, which is particularly beneficial for quenching streams after high-temperature chemical reactions.

Systems and processes for turboquenching

A method and apparatus for generating solar power in agricultural fields while minimally impacting crop growth and farming efforts, including positioning an elongated solar panel above crops, wherein the elongated solar panel runs generally parallel to longitudinal lines and wherein the elongated solar panel has at least one solar transducing face and an endless edge surrounding and perpendicular to the at least one solar transducing face, automatically pivoting the elongated solar panel such that the at least one solar transducing face is oriented parallel to incident solar rays during predetermined times when plant growth requires incident sunlight, automatically pivoting the elongated solar panel such that the at least one solar transducing face is oriented parallel to the vertical during rain, automatically pivoting the elongated solar panel out of the way of heavy farm equipment, and automatically pivoting the elongated solar panel such that the at least one solar transducing face is oriented perpendicular to incident solar rays at predetermined times when plant growth does not require direct sunlight. The elongated solar panel is positioned sufficiently above crops to give clearance to heavy farm equipment passing therebelow and/or adjacent panels are spaced sufficiently apart such that heavy farm equipment may pass therebetween.

Photovoltaic structures for use in agriculture farms

Systems and processes for dehydrogenating one or more alkanes using electrically heated dehydrogenation reactors. The source of electric energy or power can be a power grid, solar panel, windmill, hydropower, nuclear power, fuel cell, gas turbines, steam turbines, portable generator or the like. The systems and processes provided herein result in a simpler dehydrogenation process which is particularly beneficial at a small scale and at remote locations, including the well site.

Electrically heated dehydrogenation process

Processes and systems for upgrading natural gas liquids. At least a portion of the natural gas liquid components in a shale gas stream can be dehydrogenated to their corresponding olefin derivatives prior to separating any methane from the liquids. Further processing subsequent to dehydrogenation could include various separations, oligomerizing olefins produced in the dehydrogenation step, recovering desired products, etc. The order of the processing steps subsequent to dehydrogenation could be adjusted in various cases.

A photovoltaic system for generating electrical power on farmland while minimizing reduction of solar radiation incident on ground due to shadowing, including a photovoltaic module having a first photovoltaic face defining a first plane, a normal axis extending from the first plane, a first pivot axis extending through the photovoltaic module, a second pivot axis extending through the photovoltaic module, at least one motor operationally connected to pivot the photovoltaic module about at least one pivot axis, and an electronic controller operationally connected to at least one motor. An incident solar ray strikes the photovoltaic module at an angle of incidence defined as an intersection of the incident solar ray and the normal axis. The electronic controller sends signals to the at least one motor to maintain the angle of incidence as close as possible to ninety degrees.

Systems and processes for producing one or more alkenes from shale gas. The process includes at least two dehydrogenation reactors whereby propane, or a mixture of propane and butane, can be dehydrogenated in a first reactor and ethane can be dehydrogenated in a second reactor. The lighter components which serve as chemical inert and thermal mass are separated from the dehydrogenated product after each reactor.

Process to produce alkenes from shale gas

Systems and processes for upgrading natural gas liquids (NGL). A natural gas, preferably a shale gas, comprising methane and one or more natural gas liquids can be converted to one or more liquid hydrocarbons. Methane can be separated from the one or more liquid hydrocarbons using a liquid absorbent to provide a first separated stream comprising the methane from the converted stream and a second separated stream comprising the one or more liquid hydrocarbons from the converted stream. At least a portion of the one or more liquid hydrocarbons can be recycled as the liquid absorbent.

Systems and processes for upgrading natural gas liquids from shale gas

A process for producing olefins by cracking paraffins in the presence of methane. In the conventional steam cracking processes for olefin production, steam is used as a diluent in the feed mixture to the thermal cracker. In the processes provided herein, methane replaces steam as a diluent in the feed mixture to the thermal cracker. Replacing steam with methane as a diluent has a potential for cost savings in the construction and operation of a thermal cracking plant for olefin production. In addition, it leads to a much simpler cracking process compared to the conventional steam cracking technology as in the state of the art.

A method for obtaining copper arsenic chalcogen derived nanoparticles, including selecting a first precursor material from the group comprising copper, arsenic, antimony, bismuth, and mixtures thereof, selecting a second material from the group comprising sulfur, selenium, tellurium, and mixtures thereof, and then reacting both precursors in a solvent medium at conditions conducive to the formation of copper arsenic chalcogen derived nanoparticles.

Solution based synthesis of copper-arsenic-chalcogen derived nanoparticles

A direct solution method based on a versatile amine-thiol solvent mixture which dissolves elemental metals, metal salts, organometallic complexes, metal chalcogenides, and metal oxides is described. The metal containing and metal chalcogenide precursors can be prepared by dissolving single or multiple metal sources, chalcogens, and/or metal chalcogenide compounds separately, simultaneously, or stepwise. Multinary metal chalcogenides containing at least one of copper, zinc, tin, indium, gallium, cadmium, germanium, and lead, with at least one of sulfur, selenium, or both are obtained from the above-mentioned metal chalcogenide precursors in the form of thin films, nanoparticles, inks, etc. Furthermore, infiltration of metal containing compounds into a porous structure can be achieved using the amine-thiol based precursors. In addition, due to the appreciable solubility of metal sources, metal chalcogenides, and metal oxides in the mixture of amine(s) and thiol(s), this solvent mixture can be used to remove these materials from a system.
