Factors affecting the proper operation of circulation machines
Thread Content
What are the harmful effects of increased inlet gas temperature and elevated ammonia content on the circulator?
A high inlet temperature of the circulator affects its air delivery capacity; if the temperature is too high, it can also impact the service life of the valves and the cylinder body； If the ammonia content is high (i.e., what is commonly referred to as having ammonia present), it will affect catalyst operation, as well as the catalyst’s activity and lifespan.
An increase in the inlet gas temperature of the circulator leads to a higher outlet temperature, rising pressure, and a decrease in the air delivery volume； An increase in the ammonia content of the incoming gas can easily lead to the formation of ammonium carbonate crystals if there is a slight excess of copper in the washing process.
High inlet gas temperature can cause damage to the circulator valves, result in high current levels, reduce the air inflation volume, and increase the load on the heat exchangers in the synthesis tower. High ammonia content in the inlet gas leads to poor reaction performance in the synthesis tower, high pressure, low yield, and valve damage.
