摘要: Solids comprising a magnetically stabilized fluidized bed are transported in a direction transverse to the flow of the fluidizing fluid exiting the bed by contacting at least a portion of said solids with fluidizing fluid which enters the bed with a velocity component in the direction of solids flow; i.e. the transverse flow direction. In a preferred embodiment, the fluidizing fluid entering the bed is passed through a distribution means containing propulsion passages slanted in the desired direction of solids flow which serve to orient the fluidizing fluid in the transverse flow direction. Use of this invention eliminates the need for the costly and inconvenient pneumatic, hydraulic and mechanical transport devices employed in the prior art. Solids attrition and elutriation are also reduced.

摘要: This invention relates to a process for the removal of dissolved species from aqueous solutions, which comprises contacting said aqueous solution with an emulsion, said emulsion comprising an exterior phase which is characterized as being immiscible with said aqueous solution and yet permeable to said dissolved species, and an interior phase which contains a reactant capable of converting said dissolved species to a nonpermeable form. The dissolved species permeate the exterior phase, into the interior phase where they are converted into nonpermeable forms and thus retained in the interior phase of said emulsion. The aqueous solution, depleted in said dissolved species, is separated from said emulsion and the emulsion cycled for reuse. In one preferred embodiment said dissolved species are ions, and an ion exchange compound is incorporated in the exterior phase of the emulsion, to promote the permeation of said ions through the exterior phase.

摘要: The instant invention relates to a process for separating components from liquid mixtures which comprises emulsifying said liquid mixture in an immiscible liquid which is characterized as a solvent for the components. The emulsion is then contacted with an inert gas whereby the components of the mixture which, because of their solubility, permeate into said immiscible liquid, and are stripped therefrom by the inert gas. The components may then be separated from said inert gas stream by condensation and subsequent phase separation or fractionation, by absorption, distillation or by adsorption. In a preferred embodiment of the instant invention the liquid mixture comprises a hydrocarbon which is emulsified in an aqueous surfactant containing liquid. The hydrocarbon mixture contains hydrocarbons of different types, as well as hydrocarbons mixed with oxygenated compounds, i.e. alcohols, ketones, acids, and mixtures thereof. In a particular embodiment the hydrocarbon mixture contains toluene and heptane. In this embodiment the toluene preferentially permeates into said aqueous surfactant containing liquid and is removed therefrom by a stream of stripping steam.

摘要: A method is described for storing the offpeak electrical output of an electricity generating plant in the form of heat by using it to raise the temperature level of a quantity of stored heat retention material and recalling said stored heat during periods of peak power demand in the form of electrical power. During low power demand periods hot water is drawn from a hot water storage means and cooled by flashing it at successively lower pressures. The cold condensate is sent to a cold water storage means while the various flash vapors are fed to appropriate stages of a steam compressor driven by excess power drawn from the electricity generating station. The steam which has been compressed by means of the excess electrical power is directed to heat exchanger means where it is used to heat a low vapor pressure (LVP) thermal energy retention material flowing from cold to hot storage means through the heat exchanger means. By the practice of this invention, heat is transferred, by means of the steam compressor powered by excess electrical power, from hot water (.about. 210.degree. F) to the LVP material raising its temperature from a cold storage temperature of about 190.degree.-300.degree. F to a hot storage temperature of about 450.degree.-600.degree. F. The hot LVP material is stored at atmospheric pressure preferably under an inert gas atmosphere. During peak energy demand periods, the process is reversed and the hot LVP material is used to generate steam which runs a turbine thereby producing electrical power from a generator.

摘要: An integrated power generating plant includes a fuel cell for generating electrical energy directly, an auxiliary power generating plant that utilizes both the sensible heat and the heating value of effluents from the fuel cell by using working fluids in a closed cycle. The working fluid is vaporized by sensible heat and is superheated by combusting incompletely reacted fuels from the fuel cell.

摘要: The power output from a nuclear power plant or fossil fuel power plant operating under constant reactor (or furnace) and boiler conditions is varied by regulating the rate of turbine extraction steam and primary high pressure steam used to heat boiler feed water (BFW). During periods of low power demand excess extraction steam is drawn off to heat excess quantities of boiler feed water. One portion of the BFW is fed to the boiler while the other portion is used to reheat a low vapor pressure (LVP) organic material which hot material is stored under an inert atmosphere at atmospheric pressure in a high temperature storage location means. During periods of high power demand BFW preheat duties would be taken over entirely by the moving LVP organic material, moving from hot to cold storage location means, use of extraction steam for BFW reheat being curtailed and such untapped extraction steam being allowed instead to expand itself fully in the turbines. The boiler at all times receives a constant amount of uniformly preheated BFW.

摘要: In a liquid chromatography commercial process for the separation of two or more components contained in admixture in a feedstream including the steps of (a) contacting the feedstream mixture containing the components to be separated with a bed of crystalline aluminosilicate adsorbent at conditions to effect the selective retention of two or more of the components by said adsorbent, (b) passing through said bed an eluent selected from the group consisting of aromatics and substituted aromatics, (c) increasing the strength of the eluting agent in the liquid carrier during the operation of the steps (a) and (b) above, (d) recovering from said bed a stream or streams containing at least a portion of the less selectively adsorbed components, and (e) recovering a stream substantially enhanced in concentration of said selectively adsorbed components relative to other components of feedstream wherein the improvement comprises preheating the eluting agent of step (c) above prior to passing it through said bed at temperatures of at least 160.degree. C., to thereby effect the desired separation under conditions that cause substantially lower elution volume to feed ratios. The improved liquid chromatography process is particularly applicable to the separation of paraxylene and ethylbenzene from a C8 aromatic isomer mixture containing ethylbenzene. The above process when operated with the eluting agent preheating step at temperatures of about 160.degree. C or higher causes temperature waves to flow through the bed with the final peak of each feed slug being eluted with the hotter eluting agent-carrier mixture, thus providing lower elution volume to feed ratios and thereby producing paraxylene more economically.
