Synthesis tower drum

What is the impact of scaling in the vapor drum of the methanol synthesis tower on the by-product steam?
Scale formation in the drum indicates poor control of boiler water quality; the possible consequences include 1) excessive levels of sodium ions or silica in the by-product steam. 2. Poor quality of boiler water can lead to azeotrope formation between steam and water, resulting in liquid being carried in the by-product steam. 3. If the quality of the by-product steam does not meet the standards, it can affect the on-line monitoring instruments or the equipment used by steam consumers. 4. Scaling of the drum leads to uneven heating of the drum, affecting its lifespan and safety.
