H2S and NH3 Steam Stripper
Hydrocarbon gas at 160F had 8500 ppm of Hydrogen Sulfide and 7700 ppm of Ammonia. Due to very high inlet concentration Steam Stripping with two towers in series were used to remove H2S and NH3. Simulation results shows that 3 Theoretical stages are required with 17 ft packing height of 40mm VSP® or IMTP® in Stainless Steel. Tower diameter of 10 ft was calculated. In first tower, simulation results showed that 3 Theoretical trays (stages) are required to achieve 99% H2S removal and some of NH3, packing used was 40 mm VSP® in SS with packing height of 17 ft. In second tower, simulation results shows that 5 Theoretical trays (stages) are required to achieve 99% NH3 removal, packing used was 40 mm VSP® in SS with packing height of 5 ft.
