A modular rack for mounting components of a phytochemical extraction system is described. The module rack includes at least two legs and one or more frame modules that are each at least 2 units in length. Multiple frame modules can be combined to create racks of width N, where N is an integer greater than 2 units in length. Each frame module may also include mounting devices configured to removably attach extraction columns to the frame module.

Methods of reducing acid gas from a stream, comprising contacting the stream with a solvent system comprising a glycerol derivative are described herein. Disclosed herein is a composition comprising a glycerol derivative and an acid gas. A method for sweetening a natural gas stream comprising contacting a solvent system comprising a glycerol derivative with a natural gas stream is described herein.

This disclosure describes systems, methods, and devices for phytochemical extraction. One example extraction system includes two solvent columns, a material column, and a dewaxing column. The solvent columns store and provide solvent for stripping target chemicals from plant material in the material column. The solvent mixed with target chemicals passes into the dewaxing column, where the target chemicals are separated from waxes and lipids. Cooling is applied to elements of the system by way of an open-loop CO2 refrigeration method. Solvent is moved from the solvent columns to the material column by creating a pressure differential between the two solvent columns.

These liquid-liquid extractors are adapted to very low fluid flow rates passing through them. In order to reduce the influence of capillarity and air phenomena that may make the flow irregular, the outlet ducts comprise, downstream of the settling cell where the heavy and light phases separate, overflows of the phases the edge of which is irregular in height, for example serrated. The circulation channels of the phases are advantageously open to also reduce the risks of blocking by air bubbles.

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.

A system for debinding a green body in the form of an orthodontic appliance may include a pressure vessel configured to contain a supercritical fluid. A source of a fluid chemical may be coupled to the pressure vessel to supply the fluid chemical to the pressure vessel. A heat source may be configured to heat the fluid chemical. A pump may pressurize the fluid chemical to at least the supercritical pressure. A collection vessel is coupled to the pressure vessel to capture the binder removed from the green bodies as at least the pressure of the supercritical fluid is reduced. A method of manufacturing an orthodontic appliance includes exposing green bodies including particles and a binder to a supercritical fluid to remove at least some of the binder from the green bodies, and collecting the removed binder from the supercritical fluid as the supercritical fluid transitions to a non-supercritical fluid.
