Detailed description of the invention
By further illustrate technological means that this utility model taked by reaching predetermined goal of the invention and
Effect, below in conjunction with accompanying drawing and preferred embodiment, is hydrocracked according to the one that the utility model proposes
Device its detailed description of the invention of fractionating column feed system, structure, feature and effect thereof, describe in detail such as
After.
Referring to Fig. 1, it is this utility model embodiment one hydrocracking unit fractionating column feed system
Structural representation, this feed system include stripper 1, stripper base oil/product heat exchanger 2,
Stripper base oil/recycle oil heat exchanger 3, fractionating column charging separatory tank 4, fractionating column feed pump 5, fractional distillation
Tower charging heating furnace 6, fractionating column 7 and oil circulating pump 8.Wherein the tower bottom outlet of stripper 1 passes through
Pipeline is sequentially connected with stripper base oil/product heat exchanger 2, stripper base oil/recycle oil heat exchanger 3,
Then fractionating column charging separatory tank 4 it is communicated to；The gas outlet of fractionating column charging separatory tank 4 is communicated to point
Evaporating tower 7, the liquid outlet of fractionating column charging separatory tank 4 is sequentially connected with fractionating column feed pump 5, fractionating column
Charging heating furnace 6, fractionating column 7；The tower bottom outlet of fractionating column 7 is sequentially connected with oil circulating pump 8, stripping
Tower base oil/recycle oil heat exchanger 3.
This utility model one hydrocracking unit fractionating column feed system, makes stripper base oil through stripping
After tower base oil/product heat exchanger and stripper base oil/recycle oil heat exchanger heat exchange, enter into point
Evaporate tower charging separatory tank, enter fractionating column, from fractional distillation from the fractionating column charging isolated gas of separatory tank
The tower charging isolated liquid of separatory tank is fractionated into the boosting of tower feed pump, fractionating column charging heating furnace heating
Enter fractionating column later；Fractionating column base oil carries out heat exchange with stripper base oil after oil circulating pump boosts.
In the process, stripper base oil through stripper base oil/product heat exchanger and stripper base oil/
Recycle oil heat exchanger heat exchange, improves the feeding temperature of fractionating column, thus decreases fractionating column charging and add
