Solvent regeneration issue

High motor current in the MDEA solvent regeneration reflux pump – what causes the excessive flow?
High current usually implies a high outlet flow rate, or an increase in the viscosity of the medium. The reflux tank at the top of the tower generally contains acidic water; if the concentration of amine solution is high, this phenomenon can also occur
What we encountered was caused by a clogged imported filter.
If the outlet flow does not increase accordingly, consider the possibility of a clogged control valve or outlet filter. Another reason is that in winter, when the backup pump is activated, part of the flow at the outlet of the anti-freezing/anti-condensation line returns to the pump inlet; as a result, the pump is actually overloaded yet the outlet flow does not increase.
The current is too high due to excessive load or a clogged outlet filter
