What is the reason for the high viscosity of the washing oil and how to deal with it? Thank you! ! ! ! ! ! !
The distillation amount of wash oil decreases before 270~C, and increases at 270~300~C. The content of heavy components is high, including more components such as fluorene, oxyfluorene, and acenaphthene. Causes the viscosity of the washing oil to be high
Strengthen regenerator operation and timely discharge of slag； Improve the quality of the incoming washing oil to ensure that the distillation range of the incoming washing oil is not less than 75% before 270°C, and there are no 15°C crystals.
The process has a high dry point and contains heavy to heavy fractions of anthraquinone.
