Abstract In view of the situation that acid mist can not meet the emission limit requirements in Beijing, Tianjin and Hebei areas after the tail gas from sulphuric acid production is treated by high gravity technology and ammonia absorption process ,the process has been improved.The acid mist can be remedied by improving the absorption device, replacing ammonia with alkali solution and adding high precision fiber mist remover or electric mist remover.
