Abstract:
     Desulfurating liquor contains sodium carbonate (1.5-3.5g/l), sodium dicarbonate (5.0-10.0g/l) and PDS (0.5-2.5 ppm (Wt.)]. The desulfurating process for gas includes counter-current contact of sulfurating liquor at 30-50 deg.C with gas at 25-30 deg.C in a ratio of liquor to gas of 25-36 l/cu.m and spray density of 28-32 cu.m/sq.m, and continuous addition of PDS solution to desulfurating liquor, and features low cost, high desulfurating effect and no pollution.
