Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain separation processes by principle, equipment, selection, efficiency and safety, for education and engineering.

A method that converts a mixture of substances into two or more distinct product streams, such as distillation, filtration, centrifugation, chromatography, crystallisation, extraction, drying and membrane separation, used in laboratories, industry and everyday life.

What it is for: Purification, recovery and analysis of materials.

It can be choose a separation method for a mixture; explain the physical principle used; estimate efficiency and yield; operate equipment safely.

Distinguishing features

Exploits differences in properties

Produces separate streams

Often energy-intensive

Core unit operation

What it looks like

Columns, filters, centrifuges, evaporators, membranes and dryers.

How it is recognised

Distillation columns and filters

Chromatography columns

Chemical reactions change substances rather than separate them
