Leaching: is the separation of a solute from solid mixture by dissolving it in a liquid phase. Leaching occurs in two steps: 1. Contacting solvent and solid to effect a transfer of a solute (leaching). 2. The separation of the solution from the remaining solid (washing). Factors influencing the rate of extraction: There are four

Solid extraction , dissolve soluble matter from its mixture with an insoluble solid. Separate two miscible liquids by use of a solvent. 2. Leaching. Liquid extraction solid (solute A+ inert B) solvent (C) concentrated solution (A+C) overflow phase (liquid) extracted solid (A+B+C) underflow phase (slurry)
Leaching / solid extraction – methods of removing one constituent from a solid by means of a liquid solvent. • Examples: 1) Extraction of oil from soybean flakes. 2) Extraction of coconut milk from coconut. • The amount of soluble material removed is often greater than in ordinary filtration washing. • The granular feed solids
Liquid-liquid extraction involves using a liquid solvent to remove a liquid component from a liquid mixture. The component dissolves preferably in the solvent. Applications of this process include removal of vitamins from aqueous solu- tions and aromatic compounds from crude oil fractions. Ideal extraction: When the initial
When some of the original substances are solids, the process is called leaching. In a sense, the role of solvent in extraction is analogous to the role of enthalpy in distillation. The solvent-rich phase is called the extract, and the solvent-poor phase is called the raffinate. A high degree of separation may be achieved with
22 Oct 2009 Separation by extraction is based on this principle. When some of the original substances are solids, the process is called leaching. In a sense, the role of solvent in extraction is analogous to the role of enthalpy in distillation. The solvent-rich phase is called the extract, and the carrier-rich phase is called the
Solid-liquid extraction (Leaching). 4.1. Principles. The principle for the solid-liquid extraction is that the soluble compounds of a solid matter, existing of an inert matrix and the active agent, are extracted by a solvent. The extract can be included in the extraction matter in solid or liquid form. It can be included in cells like oil in
solid - liquid extraction, or leaching, where a solvent extracts a solute from a solid phase;. • supercritical extraction, where a fluid under supercritical conditions is used as the solvent. Solid-liquid extraction is also called leaching. In supercritical fluid extraction, gas at supercritical conditions contacts a solid or a liquid solution
