[0038] Example
[0039] The examples illustrate the effect of the pressure feed crude oil distillation method provided by the present invention.
[0040] As attached figure 2 As shown, the desalted and dehydrated crude oil is heat-exchanged to 205°C, and then enters the initial distillation tower 1, the gasoline component is extracted from the top of the initial distillation tower, and the bottom oil of the initial distillation tower is pressurized by the pump and heated by the atmospheric heating furnace 2 to 360°C , Sprayed into the atmospheric tower through the pressure feed system, atomized into small droplets, the pressure feed system includes a flow distribution system and atomization equipment, the flow distribution system ensures that each atomization equipment has droplets sprayed, The atomization equipment is a swirling atomization nozzle. The swirl core is placed in the front of the nozzle. A single orifice plate is installed on the top of the swirl core. The swirling l...
