This study proved the technical feasibility of a CO{sub 2}separation process based upon the regenerable noncatalytic gassolid reaction between CaO and CO{sub 2} to form CACO{sub 3}. Such a process operating at 650{degree}C and 15 atm with 15% CO{sub 2} in the coal gas has the potential for removing in excess of 99% of the CO{sub 2} fed.

This process results in the production of a flue gas that is highly concentrated in CO2, thus simplifying the CO2 capture process. An oxygen production plant is necessary. The third way to capture CO2 from a coal power plant is by IGCC with precombustion capture. This method also requires an oxygen production plant.

The primary goal of this research program was to demonstrate, in a field test, the ability of a membrane process to capture up to 90% of CO{sub 2} in coalfired flue gas, and to evaluate the potential of a fullscale version of the process to perform this separation with less than a 35% increase in the levelized cost of electricity (LCOE).

Terminology. The term carbon capture and storage (also known as carbon dioxide capture and storage) refers to a process in which a relatively pure stream of carbon dioxide (CO 2) is separated ("captured"), compressed and transported to a storage location for longterm isolation from the atmosphere.: 2221 Bioenergy with carbon capture and storage (BECCS), is a related technique that ...

1. Introduction. The first commercial membrane gas separation system was developed by Monsanto in 1979 for the separation of H 2 from CH 4, N 2, and Ar in purge gases in ammonia and chemical plants and refineries [1, 2].Since then, a number of other applications were established, including air separation by Generon (1982), H 2 purification in synthesis gas plants by Ube Industries (1987), and ...

1. Background and Motivation The total US CO2 emissions for 2006 were 5934 million metric tons (Mt). Of this, the electricity sector was responsible for 2344 Mt (%). Coalfired power plants produced 83% of the electricity sector's CO2 emissions, with most of the remaining emissions from natural gasfired power plants (EIA, 2007).
