A specific pilot plant has been achieved based on absorption/desorption process using MonoEthanolAmine (MEA) solvent. Several experiments have been carried out at laboratory and industrial site. The pilot is fully instrumented to establish precise balances. Laboratory experiments allow to measure overall mass transfer coefficient K G a w for several pilot operating conditions. Long laboratory and industrial runs provide an estimation of MEA chemical resistance against waste incinerator flue gas. The experiments also allowed the analysis of NO 2 and SO 2 absorption through the solvent as well as the accumulation of Heat Stable Salts (HSS) for a full scale CO 2 capture unit fed by a waste incinerator flue gas.

“…In der Sprudelschicht kommt es zum Stoffaustausch zwischen Gas und Flüssigphase. Unter der Annahme, dass die Konzentrations-und Temperaturgradienten entlang eines Bodens, also vom Zulauf-bis zum Ablaufschacht, relativ klein sind, kann eine homogene Durchmischung der Sprudelschicht angenommen und der Stoff-und Wärmeaustausch wie in einem axialen Segment einer Packungskolonne beschrieben werden [12]. Für die in dieser Arbeit untersuchte Bodenkolonne ist diese Annahme zutreffend.…”

“…Till now, the NO2 absorption process using chemical reagents have widely been studied to develop the industrial scale process. Many absorbents such as Ca(OH)2, CaCO3, Na2SO3, (NH4)2SO3, and CaSO3 have been tested and the reaction mechanism have been probed [1,[14][15][16][17][18][19][20][21][22]. Among them, sulfite solutions have been considered as a cost-effective absorbent because of their high removal efficiency, their desulphurization byproduct characteristics, and their capacity of simultaneous removal of mercury and chlorine [23][24][25].…”

Abstract:The simultaneous removal of nitrogen oxides (NO x ) and sulfur dioxide (SO 2 ) by absorption is considered to be one of the most promising technologies for flue gas treatment, and sulfite is the main component of the absorption solution. To understand the chemical behaviors of the NO 2 absorption in sulfite solution, the absorption time dependences of concentrations of nitrogen and sulfur compositions in both gas phase and liquid phases were investigated by flue gas analyzer, Ion chromatography (IC), Gas chromatography (GC), and Fourier transform infrared spectrometry (FTIR) methods using a bubbling reactor. The mass equilibrium of the N and S compositions were also studied. The results indicate that sulfite concentration plays a vital role in NO 2 absorption. The main absorption products are NO 3 − and NO 2 − , and NO 2 − can be converted into NO 3 − in the presence of oxygen. Besides, about 4% to 9% by-products of S compositions are formed, and 4% to 11% by-products of N compositions such as NO, N 2 , N 2 O 5 , N 2 O, and HNO 3 in the gas phase were detected in the emissions from the bubbling reactor. On the basis of N and S compositions, a possible pathway of NO 2 absorption in sulfite solution was proposed.
