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.

Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Coal mining - Prospecting and exploration | Britannica

Coal mining - Coal mining - Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam.

Coal continues to play a major role in the economic development of a country, especially in metallurgical industries and conventional power generation plants. For effective utilization of high ash coals, it is necessary to beneficiate them. The wet beneficiation process for coal cleaning is currently the predominant method of purification of coal in the world.

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 ...
