About: Raffinate

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In chemical separation terminology, the raffinate (from French raffiner, to refine) is a product which has had a component or components removed. The product having the removed materials is referred to as the extract. For example, in solvent extraction, the raffinate is the liquid stream which remains after solutes from the original liquid are removed through contact with an immiscible liquid. In metallurgy, raffinating refers to a process in which impurities are removed from liquid material.

  • In chemical separation terminology, the raffinate (from French raffiner, to refine) is a product which has had a component or components removed. The product having the removed materials is referred to as the extract. For example, in solvent extraction, the raffinate is the liquid stream which remains after solutes from the original liquid are removed through contact with an immiscible liquid. In metallurgy, raffinating refers to a process in which impurities are removed from liquid material. In pressure swing adsorption the raffinate refers to the gas which is not adsorbed during the high pressure stage. The species which is desorbed from the adsorbent at low pressure may be called the "extract" product. (en)
  • Em extração com solvente, um rafinado é uma corrente de líquido que mantem-se após a extração com o líquido imiscível para remover solutos do licor original (solução contendo a inicialmente pretendida substância a separar). Original do francês raffiner, para refinar. Na extração por solvente (uma típica extração líquido-líquido), os dois líquidos devem ser imiscíveis. Isso permitirá a separação do produto rico extraído e o rafinado empobrecido. (pt)
