Abstract

Abstract:

The basic principle of the two-membrane theory as the mass transfer theory in absorption process was briefly stated．The principle was then used to investigate the absorption characteristics of SO 2 and NO x in the process of simultaneous desulfurization and denitrification from flue gas using urea／additive solution．The experimental results show thatin urea／additive solutionthe absorption process of SO 2 in flue gas going with quick irreversible chemical reactions is controlled by the gas membranewhile that of NO x going with slow irreversible chemical reactions is controlled by both the gas membrane and the liquid membrane．

Key words: urea, additive, flue gas, desulfurization, denitrification, absorption characteristic
