White powder appears in the silicone light separation tower
Thread Content
There is no leakage in the condenser of the light fractionation tower. This powder clogs the filter of the light fractionation reflux pump, preventing the pump from functioning properly; it needs to be cleaned from time to time. Additionally, it blocks the gap between the rotor and stator of the shielded pump, causing the pump to burn out. It also adheres to the packing, so the packing must be cleaned as well. This powder is white and soluble in water. Does anyone know what could be causing this?
It may be that the light components have a lower boiling point and are more volatile; there might also be issues with the pump’s sealing, which could lead to contact with small amounts of moisture and subsequent hydrolysis.
There must be moisture that has gotten in and caused hydrolysis; otherwise, such a thing wouldn’t occur
