What is the purpose of filling the high-pressure air cooler with water?
Thread Content
Water is injected into the high-pressure air cooler because only in the presence of water can hydrogen sulfide and ammonia react and be removed; or is the purpose of water to remove ammonia? In other words, if there isn’t enough hydrogen sulfide in the system, won’t using water alone be ineffective for removing ammonia? Thank you
To prevent blockages caused by ammonia salt crystallization, water injection can be effective in prevention.
The crystallization temperature of ammonium chloride is 179 degrees, while that of ammonium sulfide is around 130 degrees; therefore, water needs to be added before these crystallization temperatures occur in order to prevent the formation of ammonium salts
Prevent ammonium salt crystals from clogging heat exchangers, pipes, and air-cooling tube bundles
It mainly reacts with ammonium salts to prevent salt buildup in the pipelines; it has nothing to do with hydrogen sulfide.
Water injection at this location is primarily to prevent blockages in the pipes caused by the crystallization of ammonium thiocyanate.
Wash away the ammonium salts to prevent crystallization after cooling, which could block downstream pipes and equipment
Prevent ammonium salt crystallization from blocking pipes
To effectively prevent ammonium salt crystallization, there should also be a certain cooling effect.
Water injection is used to prevent the crystallization of ammonium hydrosulfide from causing blockages in the pipes
