This involves equilibrating an aqueous solution that contains many different molecules with an organic solvent. The more polar molecules will stay in the aqueous solution and the more non-polar molecules will be exteacted into the organic layer.
A chemical procedure for removing one type of material from another. Extraction is generally carried out by immersing a solid in a liquid, or by shaking two immiscible liquids together, resulting in the transfer of a dissolved substance from one liquid to another. Solvent extraction is one of the primary methods of sample preparation in arson debris analysis.
The process of mining and removal of cal or ore from a mine. Return to the top of the page. FARM-IN/FARM-OUT : A joint venture or partnership where by an incoming (farm-in) partner earns an interest in a property by funding costs of exploration, while the (farm-out) partner owning the property does not contribute.
A process of treating a natural raw material with an organic solvent. The solvent portion containing the extracted material is filtered and the solvent removed. The extract will contain non- volatile as well as volatile components. Oleoresins, resinoids, concretes, and absolutes are all produced by extraction
The process of removing higher value NGL's such as ethane, propane, butane and pentane-plus from the natural gas stream. The extracted liquids are generally removed in mixes, which must be further processed in subsequent steps to separate the individual products
(a) The process of mining and removal of coal or ore from a mine. (b) The process of dissolving and separating out specific constituents of a sample by treatment with solvents specific for those constituents.
A technique for separating components in a mixture that have different solubilities. For example, caffeine can be separated from coffee beans by washing the beans with supercritical fluid carbon dioxide; the caffeine dissolves in the carbon dioxide but flavor compounds do not. Vanillin can be extracted from vanilla beans by shaking the beans with an organic solvent, like ethanol.
Absolutes, concretes, oleoresins and resinoids are produced through this process of treating plant material with an organic solvent. The solvent portion is removed upon filtering. The extract contains both volatile and non-volatile components.
Frequently a cognate for Digestion*. A process by which the essential,purer, or subtler parts of a substance are dissolved, or removed from the baser material or matrix and endowing it with great power. The extraction of elemental property.
The method by which essential oils are separated from the plant using solvents which can then be removed by evaporation. Strictly speaking distillation and expression are methods of 'extraction' but the term is generally reserved for the use of solvents.
Describes the process or method by which the flavoring and nutrient components of a mead are obtained from the raw material â€” the fruits, vegetables, and so on. Methods of extraction include pressing with a wooden fruit press; using juice extractors often called juicer-canners, which employ steam; boiling; soaking in either hot or cold water, and fermenting on the pulp, a process that lets the action of the first fermentation assist in removing the juices from fruits, vegetables or other raw material. Each method has its advantages, and meadmakers generally adopt the method that fits their equipment and their preferences. The term extraction is also used to describe the process of removing honey from the combs.
Extraction, in tactical combat and special operations use, is the process of removing constituents from a targeted site when it is considered imperative that they be immediately relocated out of a hostile environment and taken to a secured area under friendly control. Extraction may imply the rescuing of entities from grave danger or immediate conditions that they are incapable of surviving within. Both extraction and rescue may be for unsuspecting and/or unwilling persons and involving rapid deployment, dynamic defense of the moving tactical envelope and high-speed extrication by a special force protection team.
Fragrance extraction are processes which involve extracting aromatic compounds from the raw materials using various methods such as distillation, solvent extraction, expression, or enfleurage. The results of the extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.
Often called the brewing process. The coffee flavouring material is released from roasted and ground coffee particles. Hot water breaks the cell walls of the coffee particles and makes it permeable through which the required aroma contents defuse.
The process of identifying and obtaining particular information from a representation of a greater amount of information. For example, one could use a parsing or recognition process to isolate a statement of a particular fact from a larger paragraph that contains many other facts.
An umbrella term for the location, identification, recognition, and conversion of data or text from scanned images into desired electronic formats. This includes Optical Character Recognition (OCR) for converting machine-printed text into machine-readable text, Intelligent Character Recognition for converting hand-printed or handwritten text into machine-readable text, and Optical Mark Recognition (OMR) for recognising and determining the values of checked boxes and other marks. Automated extraction is an area where the cost benefits of Information Capture are obvious to a prospective customer; to get information into a computerised system without this capability, someone has to key it in. Extraction is part of Transformation. to the top
