Chapter 16 Flashcards
3 types of extraction
Leaching, Washing, Liquid-Liquid extraction
Products that are very similar but have different chemical arrangements (ex: butane and isobutane)
Isomer
Extract is also known as the ____ phase.
heavy
Raffinate is also known as the ____ phase.
light
The contact area between the extract/heavy phase and the raffinate/light phase is the ______.
interface
Phase used to describe “one that bubbles through”
Dispersed Phase
Absorption and Adsorption both require ____ _____
intimate contact
a device used to remove selected components from a gas stream by contacting it with a gas or liquid.
Absorber
a device (such as a reactor or a dryer) filled with a porous solid designed to remove gases and liquids from a mixture
Adsorber
the second solution that is formed when a solvent dissolves a solute.
Extract
a process for separating two materials in a mixture or solution by introducing a third material that will dissolve one of the first two materials but not the othe
Extraction
the original solution to be separated in liquid-liquid extraction.
Feed
in liquid-liquid extraction, material that is left after a solvent has removed solute
Raffinate
a device used to remove chemicals and solids from process gases.
Scrubber
the material that is dissolved in liquid-liquid extraction.
Solute
a uniform mixture of particles that are not tied together by any chemical bond and can be separated by purely physical change.
Solution
a chemical that will dissolve another chemical.
Solvent
Which is heavier, the extract or the raffinate?
Extract
What are the three main types of extraction columns?
Packed columns, tray columns, and mechanical columns
Crystallization is often referred to as the opposite of what other common process?
Dissolving
