The present invention relates to a method for extracting iodine from an aqueous solution, the method comprising the steps: Providing an aqueous solution containing iodide ions; Heating the aqueous solution containing iodide ions; Adding an acid to the aqueous solution to arrive at a pH from 1.5 to 2.5; Adding an oxidizing agent to the aqueous solution to arrive at a E.sub.h from 570 to 590 mV; Desorbing iodine by means of an airflow.

The present technology relates to methodologies, systems and apparatus for separating a liquid and a gas from a multi-phase flow stream. In particular, a gas-liquid separator having a curvilinear flow path sized is described. The flow path is designed to create a shift in the axial velocity of the primary flow field through the gas-liquid separator and generate a secondary flow field effect perpendicular to the primary flow field. The curvilinear flow path can minimize additional dispersion and provide improved efficiencies in fraction collection.

Various aspects of the disclosure relate to methods and systems for extracting oil from plant material. A system may comprise a gas moving device, an extraction chamber, and a condensation surface. Oil of the plant material may be volatized in the extraction chamber and then propelled by the gas moving device to the condensation surface to be collected. In various embodiments, the systems and methods allow the extraction of oil from plant material with little or no solvent.

The present disclosure provides a system for extracting terpenes and cannabinoids from plant matter without use of volatile solvents and without use of lipids as solvents. The system uses heated air, drawn through plant matter for volatilizing desired compounds, where the air is at a predetermined temperature, followed by collecting the desired compounds in a condenser.

The present technology is directed to methods and processes for optimally extracting and distilling desired natural ingredients from raw natural ingredients, involving pre-soaking the raw natural ingredients in a solvent, boiling the liquid component from the pre-soaking step, allowing the resultant vapor to contact the solid component, and passing the resultant enhanced vapor through a distillation column to obtain a desired product. Any steps of the methods and processes herein can be performed in conjunction with a vacuum or pressurizing devicethat is, at an elevated or lowered pressure compared with ambient pressure.

A dual phase re-circulating extraction apparatus comprises at least one extraction vessel, at least one separation chamber, and a circulation conduit configured to direct a process fluid into the extraction vessel, where it may come into contact with a source material to form a mixture, and is then passed to the separation chamber, where the process fluid separates from the extracted material, and the process fluid is recirculated back to the extraction vessel. The apparatus includes a gas pump, at least one heat exchanger, and a liquid pump, each connected to the conduit, to efficiently convert a relatively low pressure gas after separation to a relatively high pressure liquid or supercritical fluid for extraction. The apparatus can be configured to enable a batch mode process allowing continuous flow to the separators while the extractors are cycled online and offline in a sequence to enable servicing and reloading.

The present disclosure relates, according to disclosed embodiments, to a system for extracting an organic compound from a natural source, the system comprising a computer processor operational to control the system; a storage vessel configured to store an extraction gas, the storage vessel comprising a storage vessel outlet in electrical communication with the computer processor; a valve in electrical communication with the computer processor, the valve comprising a valve inlet and a valve outlet, wherein the valve inlet connects to the storage vessel outlet; a dynamic extraction vessel; and a spray evaporation loop system configured to receive a solute from the dynamic extraction vessel, the spray evaporation loop system comprising an injection nozzle in electrical communication with the computer processor, the injection nozzle comprising an injection nozzle inlet connected to the first dynamic extraction vessel outlet; and a cyclonic separator in electrical communication with the computer processor.

The present invention is directed to a modular distillation system incorporating a removable capsule for containing source material for extraction. Through the action of the invention, the steam distillation process described herein produces a substantially larger amount of volatile oil than a distillation system that does not use an enclosed, modular system. The present invention provides for an apparatus that allows for greater contact between the steam and plant matter during the distillation process through the use of a closed removable capsule containing relatively small amount of plant matter. Additionally, the present invention is directed to a system that allows the generation of higher quality distillate and considerably higher quantity of volatile oil extracts by forcing the steam to evenly disperse through a removable capsule, and by preventing the condensed liquid to return back to the boiling water within the vessel.

An extraction apparatus comprising a boiler, an extraction chamber for holding material from which a compound is to be extracted, and a condenser for condensing the vaporized solvent, and returning the condensed solvent to the extraction chamber. A fluid connection between the boiler and the extraction chamber allows passage of vaporized solvent from the boiler to the extraction chamber and condensed solvent from the extraction chamber to the boiler. The extraction apparatus is configured such that, when the extraction apparatus is in use, the solvent moves repeatedly through a cycle in which: the solvent vaporizes within the boiler; the vaporized solvent passes from the boiler into the extraction chamber by way of the at least one fluid connection, and bubbles through condensed solvent within the extraction chamber so as to agitate the condensed solvent; the vaporized solvent condenses in the condenser and returns as condensed solvent to the extraction chamber; the condensed solvent interacts with the material in the extraction chamber to extract the compound; and at least a portion of the condensed solvent containing the extracted compound returns to the boiler from the extraction chamber. A corresponding method is also disclosed.

A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.
