What are the reasons for an increase in the pressure drop in a distillation column?

Changes in the top pressure are primarily influenced by factors such as the reaction feed and reaction depth, the compressor speed and its counter-rotational momentum, as well as changes in the top circulation reflux and cold reflux.

Salt formation occurs in the low-temperature area at the top of the tower, resulting in increased reflux inside the tower

There are no other adjustments required for normal production; a gradual increase in pressure drop is most likely due to salt deposition, which ultimately results in diesel not being able to flow out and the crude gasoline sample failing to meet the specifications
