The Proii distillation tower is used to separate gasoline, kerosene, diesel, and other substances
Thread Content
In proii, distillation towers are used to separate gasoline, kerosene, diesel, etc. Can ordinary distillation towers not be used instead, and must a fractional distillation tower be employed? How is such a fractional distillation tower used, and does it need to be attached to the main distillation tower? Urgent, thank you!
That can’t be right. What you’re referring to is probably the distillation and separation of crude oil; a regular distillation tower will do for this purpose, with multiple side streams produced – gasoline at the top of the tower, followed by kerosene and diesel. There is no reboiler at the bottom of the tower; instead, high-temperature steam is used for stripping
Thank you for the reply from above. Then I would like to ask: does it require virtual materials for the output of the measurement line? I’m not very familiar with oil refining processes. Thank you
It is recommended to first find a book on oil refining and understand the principles before attempting simulations; otherwise, the simulations will be confusing. Simulation is merely a computational tool, not an end in itself.
Atmospheric and vacuum distillation is a very typical unit, with several mid-stage reflux streams on the main tower as well as several side streams from which products are extracted. A standard distillation column model can be used for the main tower, while a simple column model is sufficient for the side-line stripping column; the material stream from the side line can simply be led out through the corresponding section of the main tower. The side line is not virtual logistics.
I offer this suggestion for your reference: if you are analyzing the existing crude oil distillation tower and can use the available production data, you can directly apply a complex tower model； If you are designing a new tower, first use a simplified tower model to perform calculations and ensure proper material balance as well as the correct feeding location ； And then calculate using the complex tower model ； Additionally, the data must be accurate and complete. Please practice more and gain more experience.
