摘要： The present invention relates to a plate heat exchanger for treatment of a feed. The plate heat exchanger includes a plate package comprising a plurality of heat exchanging plates and defining a heating volume, a cooling volume and a plurality of process volumes. Each of the process volumes includes an evaporation section for evaporation of a part of the feed, a separation section for separating a non-evaporated part from an evaporated part of the feed, and a condensation section being arranged to condense the evaporated part of the feed. Each heat exchanging plate defines a first thermal interface between the heating volume and the evaporation section of a first process volume, a second thermal interface between the cooling volume and the condensation section of a second process volume, and at least one further thermal interface between an evaporation section and a condensation section of two adjacent process volumes.

摘要： Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an alkanolamine and converting the carbon disulfide to a higher boiling point product, thereby reducing or eliminating carbon disulfide from the product stream. Subsequent removal of the higher boiling point product via distillation can lead to a purified sulfide stream with high purity.

摘要： The present disclosure relates to the determination of analytes in a sample using chromatography. The present disclosure provides methods of separating an analyte from a sample. A mobile phase is flowed through a chromatography column. The mobile phase includes about 0.005% (v/v) to about 2.50% (v/v) difluoroacetic acid and less than about 100 ppb of any individual impurity, especially metal impurities. A sample including the analyte is injected into the mobile phase. The analyte is separated from the sample.

摘要： A method of batch distilling including providing a first substrate that upon distillation releases vapour having deleterious sulfur compounds, providing an inert still, adding the first substrate to the still, installing at least one first reactive article in the still and subsequently performing a first distillation run on the first substrate, such that the installed at least one first reactive article has a first exposed area that is exposed to the distillate, and collecting a first desired fraction from the first run. The distillation during the collection of the first desired fraction is performed at a rate of less than 5 L/(hr*m2) of collected first fraction per first exposed area. Compatible still and kit are also provided.

摘要： In-situ optical spectroscopic monitoring, characterization and feedback control of extraction and purification processes of compounds such as oils, alkaloids, flavonoids, terpenes and cannabinoids derived from plant material are described. Liquids from an extraction or purification process flow down an optically transparent tube, such as one made of glass. An in-situ optical monitoring assembly is configured to be mounted onto the tube to measure optical properties of the liquid extract or liquid condensate as it flows in the tube. Optical properties of the flowing liquid may include optical transmittance, reflectance, photoluminescence, scattering, absorbance, turbidity, nephelometry, polarimetry and colorimetry. The output of the optical monitoring assembly can be used to display spectral and other about the flowing liquid, set alarms to notify an operator of a predetermined condition such as a set point, and used to control extraction or purification process.

摘要： A mud retort assembly includes a retort that heats a fluid and thereby generates vapors, a condenser in fluid communication with the retort to at least partially condense the vapors and thereby generate a liquid, a condensate collector that receives the liquid and residual vapors via an outlet pipe of the condenser, and a collector plug having a frustoconical body that extends partially into the condensate collector at an opening to the condensate collector. The collector plug defines a central aperture that receives the outlet pipe and has an annular flange extending radially outward from the frustoconical body to rest on the condensate collector at the opening.

摘要： The invention provides a method and apparatus for purifying water. The apparatus includes a water still for receiving water and a hot air maintained in a heat-exchanging relationship to obtain a hot water and a cold air. The apparatus also includes one or more water purification units configured to receive the hot water from the water still in which the hot water is further heated using thermal energy received from one or more thermal energy sources to obtain steam and waste matter. A water purification unit of the one or more water purification units includes a waste matter remover for removing the waste matter from the water purification unit. The water still includes a heat-exchanging unit configured to receive the steam from the one or more water purification units. The steam received at the heat-exchanging unit is condensed to obtain purified water within the heat-exchanging unit using the cold air.

摘要： Integrated rotary evaporator apparatuses are provided. Such rotary evaporators include a vertically oriented evaporator for evaporating a sample to form a sample evaporate, a mixing apparatus for mixing the sample in the evaporator, a condenser for condensing the evaporated sample into a condensate, a collection vessel for collecting the condensate, a vacuum pump to create a vacuum in the evaporator, and a refrigeration system integrated into the condenser, where all components are integrated into a single apparatus. Standalone large-scale chillers for cooling a liquid, vapor or other medium are also provided. Such chillers include a heat exchanger or evaporator, a condenser, a compressor, and a temperature controller, all integrated into a single standalone chiller usable with any vessel or reservoir containing liquids, vapors or other medium from which heat is to be removed.
