WETTED BALLS COLUMN FOR WATER-ABSORPTION OF GASES FROM PHOSPHORYL NITRIC ATTACK

The mathematical model for water absorption of NOx, HF, SiF4, CO2 and H2O interphase transport consists of nine differential equations. Plug flow for gas and plug flow with axial mixing for liquid are considere d. Interesting relations are used for liquid mixing parameters calcula tion. Mass transfer coefficients are obtained from criterial equations established by authors. The model accepts that NO oxidizes to NO2 in gaseous phase. Experimental data fortify the mathematical model reliab ility.
