Low-boiling tower feed temperature

We can’t see it here, but it should have some effect: the cold load at the top of the tower decreases when the temperature is low, and increases slightly when the temperature is high. It's sufficient to keep the temperature and pressure at the bottom of the tower stable.
A lower temperature of the monomer inside the distillation water separator offers several advantages. After all, the monomer in the water separator is acidic, has a high water content, and contains impurities such as rust; as a result, it tends to polymerize on its own. The lower the temperature, the less polymerization occurs. However, from the perspective of low-column temperature control, if the temperature is too low, more heat will be consumed, which can easily lead to insufficient hot water supply and affect the distillation efficiency.
