System and Method for Continuous Stirred Tank Solvent Extraction Using Feedstock
20230149828 · 2023-05-18 ·

A feedstock processing system extracts a product from a solid using a CTSE system comprising a plurality of continuous stirred tank extraction stages arranged in fluid communication with each other in series such that effluent from one stage flows to a next stage in the series. One of the stages has an inlet to allow a measured amount of liquid solvent and the solid to be introduced to the continuous stirred tank extraction stage. The stage mixes the solid with the introduced solvent to form a homogeneous slurry to enable the product associated with the solid to be extracted with the solvent. A solid—liquid separator is arranged in fluid communication with the continuous stirred tank extraction stages, and receives an effluent from one of the stages and separates the liquid solvent containing the product from the solid to form a product-containing liquid and a product-depleted solid.

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.

Pressurized solvent extraction of plant biomass feedstocks

Methods for extracting and recovering bioactive components from a biomass feedstock with pressurized aqueous solvent solutions comprising one or more organic solutes and/or one or more inorganic solutes. The methods comprise the steps of: (i) preparing a selected aqueous solvent solution for pressurizing; (ii) providing a flow of the prepared aqueous solvent solution to a plant biomass feedstock contained within a pressure-resistant temperature-controllable reactor vessel (iii) warming the flow of aqueous solvent solution and the contents of the reactor vessel to a selected temperature; (iv) pressurizing the flow of the aqueous solvent solution and the contents of the reactor vessel to a selected pressure; (v) controllably flowing the pressurized aqueous solvent solution through the reactor vessel while maintaining the contents of the reactor vessel at the selected pressure; and (vi) collecting a flow of the pressurized aqueous solvent solution egressing from the reactor vessel for a selected period of time.

SYSTEM AND METHOD FOR EXTRACTING AND SEPARATING BOTANICAL OILS WITHOUT THE USE OF SOLVENTS

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.
