大気汚染物質除去に関する研究 : (4)FeSO_4水溶液による脱硝

Abstract

The kinetics of absorption of NO in aqueous FeSO_4 solutions were checked for wide operating conditions, i.e., for exposure times of 0.2-5000 s and NO concentrations of 100 ppm-99% by volum. For this purpose, three different types of absorbers, a wetted wall column, a quiescent liquid absorber, and a stirred tank absorber with a plain gas-liquid interface, were used. It was concluded that the chemical absorption process could be predicted satisfactorily by a theory of gas absorption with reversible reaction of the form of A + B ⇆ E using existing information on reaction on kinetics and statics.
