Cryogenic Pollutant Balances Extended Abstract

摘要

A side benefit of cryogenic carbon capture is the removal of other pollutants such as Hg, HCl,SO_2, SO_3, NO_2, and NO. While cryogenic carbon capture alone is an expensive process, theability to remove these other pollutants within the same cycle provides an added economicbenefit. This process, however, would not be economical by itself if only used to remove thesepollutants. Although Hg, HCl, SO_2, SO_3, NO_2, and NO are common pollutants, not much isknown about their properties at -135°C. The partial pressures of these pollutants had to beextrapolated from the data found on the DIPPR but give a good estimate of when these pollutantsshould be removed. The data supports a 99 percent removal of both CO_2 and SO_2 by the time thesystem has reached temperatures of -135 °C. The process is ready for a larger scale version formore testing to get the technology ready for plant scale operation.
