Extraction distillation tower
Thread Content
What are the effects of the pressure difference at the lower and upper parts of the extraction distillation tower, and what causes a sudden increase in the pressure difference at the lower part? How to adjust it, and what impact does it have on the pressure at the top of the tower?
It should not be a big problem; the vapor-liquid load in the lower section of the extraction distillation column is high, especially the liquid-phase load. The increase in pressure drop may be related to the design of the internal components
