Atmospheric And Vacuum Distillation Unit Vacuum Distillation Tower Design
Abstract: Tower equipment is an important unit operation in the production process equipment, it is widely used in chemical, oil refining, pharmaceutical, food and environmental protection industries. This design mainly for atmospheric and vacuum distillation unit vacuum distillation tower equipment design, atmospheric and vacuum distillation unit is generally referred to as the atmospheric distillation and vacuum distillation. Atmospheric and vacuum distillation is called the atmospheric distillation and vacuum distillation, atmospheric and vacuum distillation basic is a physical process. Vacuum distillation is the separation can be one of the methods of purification of organic compounds. It is especially suitable for those who failed to reach the boiling point at the atmospheric distillation is thermal decomposition, oxidation and polymerization of substances. Main process is: crude oil desalting and dehydration; Atmospheric distillation. Vacuum distillation.
KeyWords: packed tower;Float the tongue;Vacuum distillation tower;Pressure vessel
