Systems for extracting solute from a source material
Systems for extracting solute from a source material are shown and described. Each of the systems includes: a solvent source container configured to store a cooled solvent, a canister configured to contain the source material and receive solvent to produce an extract solution, and one or more extract containers in communication configured to receive and distill the extract solution, the solvent source container being configured to receive a post-extraction portion of the solvent. In some examples, the one or more extract containers are first and second extract containers that are each selectively coupleable to the canister and are selectively removable for storage of the extract mixture or the solute. In some other examples, the system further includes a cooling mechanism coupled to the solvent source container for cooling the recycled solvent within the solvent collection container.
Porous Composite Membrane for Solvent Extraction
An example porous composite membrane for solvent extraction is provided. The porous composite membrane includes a Janus membrane with a first side and a second side opposing the first side. The first side exhibits hydrophobic characteristics and the second side exhibits hydrophilic characteristics. At least one of the first side or the second side is sized to perform nondispersive membrane solvent extraction.
Extraction of botanical material using high-pressure hydrocarbons
An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.
Production of aromatics by pyrolysis, water gas shift and aromatization of CO2
Device and process for converting a feedstock of aromatic compounds, in which the feedstock is notably treated using a fractionation train (4-7), a xylenes separating unit (10) and an isomerization unit (11), and in which a pyrolysis unit (13) treats a second hydrocarbon-based feedstock, produces a pyrolysis effluent feeding the feedstock, and produces a pyrolysis gas comprising CO, CO2 and H2; a WGS water gas shift reaction section (50) suitable for treating the pyrolysis gas and for producing a WGS gas enriched in CO2 and in hydrogen; a CO2 aromatization reaction section (52) suitable for: at least partly treating the WGS gas to produce a hydrocarbon effluent comprising aromatic compounds, and feeding the feedstock with the hydrocarbon effluent.
Electro-Pressure Membrane Method for Recovery and Concentration of Lithium from Aqueous Sources
A hybrid electro-pressure driven method for the recovery, purification, and concentration of lithium salts is described. A fractionating electrodialysis stack equipped with selective ion exchange membranes is s used to separate a lithium containing brine into a monovalent enriched fraction and a divalent enriched fraction. The monovalent enriched fraction is further processed to remove remaining impurities by use of pressure driven nanofiltration. An optional concentrating electrodialysis device may further concentrate the monovalent enriched fraction in lithium content. The method may be combined with a subsequent solvent extraction and electrolysis step to produce lithium hydroxide, a Li+ selective sorbent step for producing purified lithium chloride, or a Li+ selective sorbent and precipitative step to produce lithium carbonate.
METHODS AND APPARATUS FOR TRANSMITTING RACH IN WIRELESS COMMUNICATION SYSTEM
The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a terminal in a wireless communication system includes receiving configuration information regarding a random access channel (RACH) from a base station, and transmitting a RACH preamble based on the configuration information. The configuration information includes information indicating the number of RACH transmission occasions in a frequency axis. A terminal includes a processor configured to receive configuration information regarding a RACH from a base station, and transmit a RACH preamble according to the configuration information, wherein the configuration information includes information indicating the number of RACH transmission occasions in a frequency axis.
Hybrid extraction process for cannabinoids and related methods
The present invention relates to methods for treating cannabis biomass in order to isolate tetrahydrocannabinolic acid (THCA). In another aspect, the present invention relates to a process that involves purification followed by extraction of cannabis biomass to isolate and improve yields of high-purity crystalline extracts.
Integrated desolidification for solid-containing residues
A desolidification process enables the isolation and extraction of solid additives from an unreacted petroleum residue stream. In a hydrocracking process that mixes a solid additive with a petroleum residue feedstock to convert the petroleum residue to higher-value distillates, the desolidification process enables the recovery of the unreacted petroleum residue for conversion to a saleable product. The desolidification process involves the mixture of one or more solvents with a slurry in which solids are integrated in the petroleum residue to generate a mixture having a decreased density and viscosity as compared to the slurry, which facilitates removal of the solids.
Methods of isolating phenols from phenol-containing media
Methods of isolating phenols from phenol-containing media. The methods include combining a phospholipid-containing composition with the phenol-containing medium to generate a combined medium, incubating the combined medium to precipitate phenols in the combined medium and thereby form a phenol precipitate phase and a phenol-depleted phase, and separating the phenol precipitate phase and the phenol-depleted phase. The methods can further include extracting phenols from the separated phenol precipitate phase. The extracting can include mixing the separated phenol precipitate phase with an extraction solvent to solubilize in the extraction solvent at least a portion of the phenols originally present in the phenol precipitate phase.
Production of aromatics by reverse water gas shift, fermentation and recycling to pyrolysis
Device and process for the conversion of a feedstock of aromatic compounds, in which the feedstock is treated notably by means of a fractionation train (4-7), a xylene separation unit (10) and an isomerization unit (11), and in which a pyrolysis unit (13) treats a second hydrocarbon feedstock, produces a pyrolysis effluent feeding the feedstock, and produces a pyrolysis gas comprising CO, CO.sub.2 and H.sub.2; a reverse water gas shift RWGS reaction section (50) treats the pyrolysis gas and produces an RWGS gas enriched in CO and in water; a fermentation reaction section (52) treats the RWGS gas enriched in CO and in water, to produce ethanol and recycle the ethanol to the inlet of the pyrolysis unit.
