A system for extracting oil from plant material includes a gas moving device propelling a gas stream, the gas stream being a stream of air or gas with or without entrained vapor, solids or droplets of liquid therein. The gas stream is directed through an extraction chamber, which is operable to volatize at least a portion of an oil from a plant material such that the volatilized oil is disposed in the gas stream as an extracted oil. A collection chamber is in communication with the extraction chamber such that the gas stream flows through the collection chamber. The collection chamber has collection solvent operable to collect at least a portion of the extracted oil from the gas stream. A liquid collector is in fluid communication with the collection chamber for collecting at least a portion of the collection solvent and extracted oil.

A fractional extraction apparatus comprises one or more extraction vessel configured to receive a process fluid, allow the process fluid to come into contact with a source material within the extraction vessel under either of a selectively configured first predetermined pressure and a first predetermined temperature to remove a first predetermined extracted material from the source material to form a first mixture or a second predetermined pressure and a second predetermined temperature to remove a second predetermined extracted material from the source material to form a second mixture. The apparatus further comprises one or more separation chamber and a circulation conduit, the conduit including a separation portion configured to receive the first or second mixture and permit a portion of the first or second predetermined extracted material to separate from the mixture within the separation chamber. The apparatus further comprises a temperature regulator configured to regulate the temperature of the process fluid during extraction. The apparatus further comprises a thermal manager configured to regulate the temperature of the process fluid during recirculation. The apparatus further comprises one or more filter plugs configured to retain a filter at the opening of the extraction vessel.

An apparatuses used for the safe dispensation of compressed liquid/gas butane from a compressed liquid/gas butane can for use in mixing this liquid/gas with parts of a marijuana plant within a glass tube of the apparatus to thereby remove the THC from the marijuana plant and disposing it and the residual liquid/gasses into a capture member for further processing.

A system for extracting oil from oil-bearing plant parts has an extraction vessel supported by an upright stand, a separator vessel mounted below the extraction vessel, and an expansion filter vessel mounted downstream from the separator vessel. A source of hydrocarbon solvent supplies liquid gas to the top of the extraction vessel, while a recycling pump connected to the separator vessel facilitates transport of the solvent through the plant material in the extraction vessel. The solvent is recovered and re-circulated, while extracted oil is removed from the separator. A computer-based temperature control assembly having a cooling device and a jacketed injection coil regulates temperature of the solvent delivered to the extraction assembly. A thermal jacket is mounted on each of the separator vessel and the expansion filter vessel, with the thermal jackets supplying heat and cold to the interior of the separator vessel and the expansion filter vessel and helping evaporate and condense the solvent.

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.

A novel system and method for degassing H.sub.2S and H.sub.2S.sub.x from liquid sulfur (sulphur) is disclosed. The system includes a degassing vessel with a plurality of cells. The cells include a sparging gas mat with a perforated surface at the bottom of the cell to allow the release of air bubbles (or sparging gas) into the cells. A catalyst may be used during the process. As a result, hydrogen sulfide and hydrogen polysulfide are efficiently and effectively removed from the liquid sulfur.

Extraction units are constructed having at least one extraction chamber containing extractable material. The extract is continuously separated from the solvent in an expansion chamber where it is continuously or periodically removed from the unit. One or more means for fluid flow can be used to circulate the fluid through the extraction chambers and the expansion chamber, where the expansion chamber and a condenser or the output of the means for fluid flow are coupled as a heat exchanger.

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.

Various aspects of this patent document relate to a method to extract an oil from a plant material using an apparatus by first exposing the plant material to a heated gas stream at a temperature sufficient to volatilize the oil from the plant material, and then rapidly cooling the gas stream to liquefy the oil.
