Who can determine whether the reboiler of the atmospheric tower in a three-column distillation system is leaking using the simplest method?
When the conditions of temperature and pressure are normal, unsatisfactory results in the analysis of the product and residue from the pressurized tower are usually due to a leak in the reboiler of the atmospheric pressure tower
You need to accumulate long-term operational experience by listening and observing more
If the reboiler of the atmospheric pressure column leaks, it will cause the temperature and pressure at the bottom of the column to increase, the liquid level at the bottom of the column to rise, and the liquid level in the reflux tank of the pressurized column to drop
Turn on the drain valve and check whether a methanol smell can be detected
If the analysis of the adjusted residue is still unsatisfactory or extremely high, it indicates a leak inside the reboiler of the atmospheric pressure column; this is equivalent to having the feed inlet at the lower part of the column, with no stripping section.
