Precipitation, electrostatic spent acid decomposition

Fig. 6.2. Dehydration of metallurgical and spent acid decomposition furnace offgas. Dehydration is done after (i) H20(g) has been condensed by gas cooling and (ii) aqueous mist has been removed by electrostatic precipitation (not shown). The gas leaving dehydration contains 50 milligrams of H20(g) per Nm3 of gas. The acid plant s main blower is situated immediately after dehydration.
