On the scaling problem in distillation towers
Thread Content
How does your factory address the scaling problem at the lower part of the distillation tower (crude benzene)? (Oil side)
It should be resolved at the root level to prevent water from entering the oil
Improving steam quality can reduce scaling.
3# Lao Qiu: I believe that the scaling in this case is mainly caused by the heavy components in the oil being distilled out, resulting in the formation of substances such as asphaltenes. It is recommended that you check the temperature inside the asphalt distillation tower, the temperature of the steam entering the tower, as well as the amount of asphalt produced. You should also examine the naphthalene content in both the rich and lean oils.
