Reflux device of the packed tower
Thread Content
Dear experts, I would like to ask: what should be done if the condensate from the condenser of a hydrochloric acid stripping column cannot return to the column? The pumps are all in good condition, and the temperature of the gas-phase output is also normal. (Condensation is carried out via an external condenser, with a return pump.)
By \"not being able to return to the tower,\" does it refer to phenomena such as flooding? If so, it is recommended that you recalculate the packing flux and gas velocity
It’s either flooding or simply an inability to return the liquid to the tower; the liquid level in the reflux tank doesn’t drop and keeps rising steadily, so the only option is to discharge it externally.
Are the process settings correct? For example, things like blind flanges and whether the pipelines are unobstructed; in theory, if there is an obstruction, the pressure will be very high
The flow is unobstructed and the tower pressure is normal; it’s just that the material can’t return to the tower. A major shutdown for maintenance is likely required
