An Introduction to CO2 Separation and Capture Technologies

An Introduction to CO2 Separation and Capture Technologies Howard Herzog MIT Energy Laboratory August, 1999 In general, to economically sequester CO 2 produced from power plants, one must first produce a relatively pure, high pressure stream of CO 2 1. There are exceptions to this rule, some of which will be explored later in this paper.

Air separation - Wikipedia

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.. The most common method for air separation is fractional distillation.Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.

Jig concentrators - Wikipedia

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ...
