Ammonia emission kinetics of monoethanolamine (MEA) based CO2 absorption process

► NH3 emission rate is dependent on MEA, O2, CO2, H2SO3, HNO3, and temperature. ► Kinetic equation of NH3 emission in MEA based CO2 absorption system is proposed. ► The equation is useful to operators to quickly get NH3 release from CO2 process.
