A calculation problem related to a fractionating tower; let’s do the math

2018-04-06 View Original

Thread Content

The flow rate from the bottom of the wax oil hydrogenation hydrogen sulfide removal stripper to the main distillation tower is 450 t/h. The flow rate of the residue leaving the plant is 80 t/h, the flow rate of diesel leaving the plant is 150 t/h, the internal reflux of diesel is 20 t/h, and the flow rate of jet fuel leaving the plant is 110 t/h. The flow rate of crude naphtha from the top of the distillation tower to the absorption tower is 60 t/h, while the flow rate of steam used for stripping at the bottom of the tower is 2 t/h. Calculate the flow rate of gas in the vaporization holes of the diesel extraction stage in tons per hour.
