Condensate, Raffinate and Cut Products

Condensate is a generic term that many use to describe a variety of light petroleum streams that range from NGLs to light crude oil. Strictly speaking, a condensate is a mixture of hydrocarbons that exists in a gaseous state in an underground gas reservoir but condenses under atmospheric conditions.

Raffinate is a product which has had a component or components removed. The product containing 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.
