What is raffinate?

What is raffinate?

Definition of raffinate : a liquid product resulting from extraction of a liquid with a solvent also : the less soluble residue that remains after extraction (as in refining lubricating oil)

What is raffinate oil?

Mixed C4s, also known as Crude C4, Raffinate 1 or Raffinate 2, are colourless gases (liquid under pressure), with a mild, petroleum-like odour. Raffinate 1 is the product remaining when butadiene is extracted from a lower olefin stream (known as crude C4).

What is raffinate in chemistry?

raffinate in Chemical Engineering A raffinate is the liquid which comes out of an extraction process involving two liquids. In solvent extraction, a raffinate is a liquid stream that is left after the extraction with the immiscible liquid to remove solutes from the original liquid.

What is extract and raffinate?

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. The species which is desorbed from the adsorbent at low pressure may be called the “extract” product.

What is a raffinate stream?

raffinate in Chemical Engineering In solvent extraction, a raffinate is a liquid stream that is left after the extraction with the immiscible liquid to remove solutes from the original liquid.

What is raffinate phase and extract phase?

Liquid extraction is the separation of the constituents of a liquid by contact with another insoluble liquid called solvent. The constituents get distributed between the two phases. The solvent rich phase is called extract and the residual liquid from which the solute has been removed is called raffinate.

What is extract and raffinate in extraction?

Liquid extraction is the separation of the constituents of a liquid by contact with another insoluble liquid called solvent. The solvent rich phase is called extract and the residual liquid from which the solute has been removed is called raffinate.

Is raffinate flammable?

Hazard statements : Extremely flammable liquid and vapour. May be fatal if swallowed and enters airways. Causes skin irritation. May cause drowsiness or dizziness.

What is raffinate gasoline?

Glossary Terms ยป Raffinate. The residual product left after a reforming process. The term also has been more generally used in reference to any low octane product left over after any secondary refining process. Preferable to natural gasoline in ethanol/gasoline blends because of the low RVP (4 to 8).

What is the meaning of raffinate in chemistry?

Raffinate. 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.

What is raffinate in solvent extraction?

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.

What is raffinose?

The portion of an original liquid that remains after other components have been dissolved by a solvent. [French raffiner, to refine; see raffinose + -ate .]

What is meant by raffinating in metallurgy?

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.
