What harm does excessive ammonia or water in acidic gas cause to the equipment? Answer: ① Acidic gas contains excessive ammonia: If, in devices other than (II) sewage stripping acidic gas, the ammonia concentration in the acidic gas is greater than 5%, hydrogen sulfide and ammonia crystals will precipitate from the acidic gas, causing blockages in pipelines and equipment ； If the ammonia concentration in the acidic gas entering the reactor is higher than 8%, it exceeds the allowable level for ammonia in the ammonia combustion process within the reactor. As a result, ammonia does not burn completely upon entering the reactor, and sulfuric acid amine crystals form in the areas of the equipment where the temperature is lower, leading to blockages in the pipelines and equipment of the facility. ②Acidic gas contains an excessive amount of water: the normal vapor content of water in acidic gas is 5.8% (V), and the absence of condensed water has no impact on the equipment. However, if the water content in acidic gas exceeds 5.8% (V), it will cause an increase in the pressure within the system, fluctuations in the temperature of the reaction furnace, increased gas consumption by the equipment, and a decrease in sulfur conversion rate; in severe cases, this can lead to accidents. Therefore, the dehydration process in the acidic gas degassing tank must be enhanced to prevent acidic gas containing free water from entering the reaction furnace.

Reduced conversion rate, increased load on the furnace, excessive system pressure, rapid drop in furnace temperature, catalyst prone to pulverization
