Abstract:

The conditions of scale formation of the waste water containing oil and ammonia in he stripping system and the principle of scale prevention and removing with quantum tube passage clearing ring are described. According to the features of the scale in the ammonia liquor stripping system, a quantum tube passage clearing ring is installed on the main pipeline for incoming ammonia liquor. Through 4-year continuous running, it is proved that the quantum tube passage clearing ring can remove the existing scale, prevent the formation of new scale effectively and ensure the stable operation of the ammonia liquor stripping system.
