A process for the treatment of waste water, spent air, and hydrocarbon containing liquid and gaseous streams in the cumene/phenol complex is described. Various effluent streams are combined in appropriate collection vessels, including a spent air knockout drum, a hydrocarbon buffer vessel, a fuel gas knockout drum, a phenolic water vessel, and a non-phenolic water vessel. Streams from these vessels are sent to a thermal oxidation system.

A chloride salt eliminator system and method for removal of chloride salt from glycol circulated through a reboiler in natural gas dehydration, in a continuous process, close to the wellhead. Hot glycol from the reboiler is pumped into a salt eliminator unit having independently replaceable filter elements which trap chloride salts which are not soluble in hot glycol and pass clean glycol for return to the reboiler.

Disclosed herein is a method for obtaining compounds and compositions from plant and fungus materials by thermal treatment, affinity capture, filtration, and release through multi-phasic transitions between gas, solid, and liquid states. The compounds of interest are obtained by manipulating the temperature and pressure of the heating chamber. The compounds in gas phase are passed through an affinity medium which captures the compounds of interest in either solid or liquid phase by exposing the compound of interest to the localized micro-affinity environment of the medium. The compounds are separated from the medium using direct competition with solvent or buffers optimized for the specific chemical properties of compounds.

A method for purification and separation of cannabinoids, such as cannabidiol and tetrahydrocannabinol, e.g., from dried hemp and cannabis leaves can use a continuous simulated moving bed process, a batch column chromatography method, or a single column, and a combination of one or more of a sequence of purification steps including: filtration, decolorization, activation or decarboxylation, dewaxing, polishing, and crystallization to separate a cannabinoid from the cannabis plant and to provide various cannabinoid products. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.

Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.

The present disclosure discloses a method for preparing 2,5-dimethylphenol by selective catalytic conversion of lignin, relates to the technical field of chemistry, and includes the following steps: mixing lignin, a catalyst, and ethanol, and then carrying out a catalytic conversion reaction of lignin under the gaseous supercritical conditions of ethanol; and cooling the reaction product by quenching after the completion of reaction, and then subjecting it to separation and extraction to obtain 2,5-dimethylphenol. The catalyst comprises a modified sepiolite carrier, an active metal Mo, and auxiliary agents Zr and Fe. The process of the present disclosure is simple, and the prepared catalyst is a solid catalyst, which avoids problems of difficult recovery, serious environmental pollution and equipment corrosion caused by the use of homogeneous organic acid-base catalysts.
