liquefy SF6 N2 Mixtures Zero emission

A gasification chamber is a high pressure/high temperature reaction vessel used to contain a mixture of O2, H2O, and coal (or other carbon containing materials) while it is converted into thermal energy and chemicals (H2, CO, and CH4). IGCC systems are expected to play a dominant role in meeting the Nation's future energy needs.

    This is a zero-emission technology, given that the combustion products contain only carbon dioxide and water vapor, enabling the complete capture of the CO2 produced. The use of oxygen-enriched air poses safety issues, since pure oxygen increases the laminar burning velocity and enlarges the flammability range with respect to air (Scott et al
