ABSTRACT:
A process for absorbing SO.sub.2 from a gas in a packed column employs a low aqueous sulfite feed rate of 0.05 to 1 gallon per minute per square foot of tower cross section, or preferably 0.1 to 0.3 gallons per minute per square foot. Lower capital costs and lower operating costs result because of less tower equipment, lower pressure drop, reduced oxidation to sulfate, and elimination of pump around as compared to the conventional processes. Also disclosed is an improved liquid distributor.
