Systems and methods for selectively recovering a target metal from an ion exchange resin are generally described. In certain embodiments, such methods and systems can be employed for metal purification and enrichment of target metal species from mixtures containing contaminating or non-target metals. In some embodiments, ion exchange is accomplished in the presence of one or more species that facilitate the recovery of a metal from a composition further comprising one or more other metals. The recovered metal-containing composition may contain the recovered metal at relatively high purity and/or in relatively large amounts. In some embodiments, the conditions present during ion exchange are varied in a manner that facilitates the enrichment of a metal from an initial (e.g. sample) composition further comprising one or more other metals to result in a product that contains the enriched metal at relatively high purity and/or in relatively large amounts.

Chromatography systems and methods for using carbon dioxide to separate one or more cannabis-derived compounds from other components of a mixture are generally described. Some of the methods described herein comprise transporting a mixture comprising a first cannabis-derived compound and one or more other components through a chromatography column containing a stationary phase comprising a packing material. In some embodiments, the mixture is transported through the column within a mobile phase that comprises carbon dioxide (e.g., supercritical CO, liquid CO). The mobile phase may be substantially free of a co-solvent that is in liquid phase at standard room temperature and pressure. In some embodiments, the mobile phase is free of any co-solvent and comprises 100 vol % carbon dioxide. The first cannabis-derived compound may interact with the stationary phase and/or the mobile phase to a different degree than the one or more other components of the mixture, causing at least partial separation of the first cannabis-derived compound from the one or more other components within the column. Due to this separation, at least one fraction of the mobile phase that comprises the first cannabis-derived compound and is substantially free of the one or more other components of the mixture may be collected.

Systems and methods for separating cannabis-derived compounds using chromatography with liquid or supercritical carbon dioxide

The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO), with reactants of nitrous oxide (NO) or oxygen (O).

Apparatus for extraction of hydrocarbon fuels or contaminants using electrical energy and critical fluids

A method of cleaning an industrial tank using electrical energy and critical fluid comprises the steps of transmitting electrical energy into an industrial tank to a first predetermined temperature, providing a critical fluid with a reactant or catalyst into the tank for diffusion into the contents of the tank at a predetermined pressure, transmitting electrical energy into the tank to heat the contents including the critical fluid to a second predetermined temperature to initiate reaction of a reactant in the critical fluid with a portion of the contents of the tank causing hydrocarbons and contaminants to be released for extraction as a vapor, liquid or dissolved in the critical fluid. A step of pressure cycling may be performed prior to a step of removing the contents of the tank including the hydrocarbons and contaminants. A further step includes separating the hydrocarbons, critical fluid, gases, and contaminants removed from the tank.

A closed loop system for increasing yield, reducing post process pollution, reducing energy consumed during and after extraction of fuels or contaminants in formations and for sequestering of carbon dioxide C0from various sources is converted to a critical fluid for use as a flushing and cooling medium. Electrical energy heats a hydrocarbon rich formation resulting in the extraction of hot fluids which are fed to heat exchangers, gas/liquid separator, and steam turbine whereby oil, electric power, carbon dioxide and methane are produced for reuse in the system or for external use. Further, a method for sequestering of carbon dioxide in a formation comprises the steps of injecting COinto the reservoir, flushing with cool pressurized COfor heat removal, infiltrating with ultra-fine low density suspended catalyst particles of dry sodium hydroxide in CO, pumping water moistened COinto the reservoir to activate the catalysts, binding the COwith reacting materials and capping the reservoir.

An apparatus and method for extraction of chemicals from an aquifer remediation aqueous effluent are provided. The extraction method utilizes a critical fluid for separation and recovery of chemicals employed in remediating aquifers contaminated with hazardous organic substances, and is particularly suited for separation and recovery of organic contaminants and process chemicals used in surfactant-based remediation technologies. The extraction method separates and recovers high-value chemicals from the remediation effluent and minimizes the volume of generated hazardous waste. The recovered chemicals can be recycled to the remediation process or stored for later use.

An improved approach for cleaning and recycling materials is based on pressurized solvents including liquid propane, butane, dimethyl ether, and supercritical carbon dioxide. The approaches are particularly suitable for cleaning sorbent materials. The approach allows for recycling of the sorbent materials, the solvent and the contaminents, typically oils and the like.

Removal of contaminants from materials

A method for providing aerogels, and aerogels produced according to the method, is described. As one aspect, antiperspirant compounds that are in aerogel form, and antiperspirant and deodorant compositions including such salts, are described. The method involves contacting a solution containing material to be processed with a species selected to precipitate the material and selected so as to be miscible with the solvent system of the solution. After the material is precipitated, the material may be washed with the precipitating species until it is substantially free of solvent system. Then, the precipitating species containing the material precipitate is taken above its critical point, and the supercritical fluid is exhausted above its critical temperature. Alternately, a separate isolating species is introduced to displace the precipitating species, or the precipitating species/solvent system mixture. The isolating species then is taken above its critical point, and exhausted above its critical temperature. The invention provides for batch or continuous processes.

Method of forming particles using a supercritical fluid

A method and apparatus for continuously separating polymer from a plastic, and the resulting separated polymer. The plastic is made flowable into a stream through melting or solubilizing. A critical fluid, such as supercritical carbon dioxide, is added to the plastic stream to promote mechanical or thermodynamic separation of the polymer from contaminants and other components of the plastic.

Disclosed are a fluid extractant, and a process and apparatus for using the extractant to separate an organic liquid from an aqueous mixture. The extractant comprises a first fluid solvent which is a gas in its near-critical or supercritical state and a cosolvent. A preferred first fluid solvent is near-critical liquid carbon dioxide. Preferred cosolvents are 2-ethyl hexanol for ethanol extraction, and hexanoic acid for acetic acid extraction. Organic compounds such as monohydric alcohols, monoacids, ketones, ethers, aldehydes and esters can be recovered from dilute aqueous solutions more economically than possible by prior art processes of distillation.
