Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the watergas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.

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).

Pre combustion process is related to the treatment of synthesis gas (syngas) composed principally of CO and hydrogen [6].Precombustion rate is premised on the production of syngas, removal of CO 2 and combustion of H 2 [7].In some ways it is oxymoron because CO 2 is obviously not normally available for capture prior to combustion, as CO 2 is a product of coal combustion, not a natural precursor.

The first commercial interest in the separation of CO 2 from flue gas was its application for enhanced oil recovery (EOR) (Herzog et al., 1997).Application of CO 2 for EOR started in the 1970s and has proved to be an effective economic approach over the years (Long et al., 2006).When the amount of CO 2 product from natural gas purification is insufficient, the CO 2 from flue gases emitted from ...

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 ...

This work attempts to address the quest of removing carbon dioxide from flue gas streams to help preserve the environment. It is based on a model that is able to describe the solidliquidvapour and solidvapour phase equilibria for the ternary system of N2O2CO2 at pressures from 5 to 130 bar and over a wide range of temperature (140 to 220 K). Furthermore, a corresponding stateofthe art ...
