| titleOfInvention | Desulfurization purification process for acidic water stripped ammonia gas |
| abstract | The invention provides a desulfurization and purification process of acidic water stripped ammonia gas, which mainly comprises a heater and H along the flow direction of the ammonia gas 2 The system comprises a direct oxidation reactor S, two condensers which are connected in parallel or can change the serial sequence, and two catalytic oxidation adsorption desulfurization towers which can be connected in series and parallel; front setting of heater H 2 An S concentration online analyzer, an oxygen distribution pipe and a mixer are fully and uniformly mixed and then enter a heater; h 2 S direct oxidation reactor filling TiO 2 Recovering a catalyst based on sulfur, and filling a catalytic oxidation adsorption desulfurizing agent prepared by modifying activated carbon in a catalytic oxidation adsorption desulfurizing tower; h 2 The temperature of the inlet air of the S direct oxidation reactor is 190-210 ℃, and the space velocity of the catalyst is 100- ‑1 The bed temperature is 210-260 ℃, and H in ammonia gas at the outlet 2 S 200‑500ug/g NH 3 ，SO 2 ≤300 ug/g NH 3 (ii) a The temperature of the inlet air of the catalytic oxidation adsorption desulfurization tower is 10-50 ℃, and the air speed of the desulfurizing agent is 10-100h ‑1 And H in the outlet ammonia gas 2 S≤3ug/g NH 3 ，SO 2 ≤1ug/g NH 3 Organic sulfur is less than or equal to 1ug/g NH 3 。 |
