Is it feasible to install a vacuum tower in a naphtha distillation unit?
Thread Content
Colleagues, currently there is a shortage of heating sources for the naphtha distillation unit; it is necessary to lower the boiling points in order to operate the distillation tower under reduced pressure. Is this feasible from a design perspective? Are there any successful cases?
The cost is too high; try air lift blowing
It is necessary to calculate the strength of the structure below the tower; the tower should not be completely deformed and rendered unusable as a result
By the way, it’s possible to conduct research on using the distillate from the tower top as a heat source for heat pumps; this should be feasible. —— Qingdao Xinhuiquan Technology Development Co., Ltd. Yang 13792908929
Could you share the process flow and operating procedures for the naphtha distillation unit? It’s also possible to send it via email to 18454601744@163.com
Reducing the operating pressure is feasible, but negative pressure operation is not possible without recalculating the tower. The biggest problem after reducing the pressure is that the load on the tower will decrease significantly, which may result in it failing to meet the required processing capacity.
