De-gumming tower
Thread Content
The boiling range of the feedstock is 125–210°C, with a gum content of 200 ppm. The gums are removed using a degumming column; the pressure at the top of this column is -0.07 MPa. This pressure forms naturally but varies significantly depending on the feedstock. As the initial boiling point of the feedstock decreases and after operation for some time, the efficiency of gum removal declines. Some studies suggest that gums, falling within this boiling range, are neither heavy nor light components; they accumulate in the distillation section of the column, and when there are fluctuations in column operation, they are discharged from the top of the column. Do anyone else have any other opinions?
What raw materials are used for degumming? And what are the principles and processes involved? Could you please explain it briefly?
