Atmospheric and vacuum distillation unit
Thread Content
In a atmospheric and vacuum distillation unit, the temperature in the atmospheric furnace is around 350 degrees Celsius. How can atmospheric wax oil and atmospheric residue be separated?
Gasoline and diesel are separated from the atmospheric distillation column, while wax oil is separated in the vacuum distillation column.
The question isn’t quite clear. Does “the boiler temperature is known” refer to the temperature of the heat source that can be provided? This should have no direct relation to the separation of atmospheric wax oil and residue
Bro, what does Chang Sanxian release?
What is the boiling range of paraffin oil, and what is the boiling range of residue oil?
Changding gasoline HK-180; Chang first-line oil: 180-220; Chang second-line oil: 230-310; Chang third-line oil: 320-350; Chang bottom oil. Reduced pressure gas; reduced pressure oil; reduced first-line oil: 350-420; reduced second-line oil: 420-480; reduced third-line oil: 480-500; reduced pressure residue: >510
Bro, what’s the temperature at the outlet of the pressure relief furnace? Around 360°, right?
Normal furnace outlet: 365; Reduced furnace outlet: 400
Extract the fourth line connected to the constant pressure system, and try increasing the steam supply at the bottom of the constant pressure tower
Draw off four lines from the constant pressure column to increase the steam supply at the bottom of the column.
