Ammonia spraying cooling nozzle for ammonia synthesis plant
Thread Content
Recently, someone asked me to design a small nozzle for an ammonia synthesis plant. Its function is to add ammonia for cooling (liquid ammonia) at the appropriate time; let’s discuss what shape this nozzle should have to be most suitable ? I am not familiar with ammonia synthesis plants, and I hope to find answers and gain knowledge through everyone’s discussions. If anyone has expertise in this area, I would appreciate some guidance. I couldn’t find any relevant posts on the forum
In the case of continuous flow within a pipe, atomization is required as soon as possible to accelerate the vaporization of ammonia. If it is in a container, it is necessary to monitor the liquid level and pay attention to gas-liquid separation; no special requirements exist for the nozzle. But in terms of the manufacturing process, attention should first be paid to the chemical properties of ammonia and the medium
Is there any relevant material available? ? Share below
This is not a continuous flow; liquid ammonia is added for cooling only when the system temperature rises due to excessive heat generated by the continuous operation of the anti-surge mechanism or high flow rates
This nozzle should be the same as the boiler feedwater nozzle used for cooling superheated steam; there’s nothing special about it.
