Abstract
The liquid level controlling system of ammonia cooler could not simultaneouly satisfy two production modes of the cold ammonia and the heat ammonia in the operation of synthetic ammonia plant.An auxiliary reacting regulator was added in the internal configuration.The results of application showed that the improved controlling system could be regulated stably in two production modes and could satisfy the needs of production process.
