Carbon dioxide is the major atmospheric contaminant leading to temperature increase caused by greenhouse effect. From 1750 until 1998 the concentration of CO 2 in the atmosphere has increased from 280 ppm to almost 380 ppm. Known anthropogenic sources account for 7 billion metric tons per year. The principal anthropogenic source is the

Electrostatic Separation of Carbon Dioxide by Ionization in Bifurcation

ABSTRACTCarbon dioxide is one of the major green house gases as well as impurities in process gases used for various manufacturing industries. In the present work our recently developed ionization separator (Ito et al. Ind. Eng. Chem. Res. 42 2003) was applied to the separation of carbon dioxide from inert gases. As a result it was found that carbon dioxide can be separated
