IPC Classification: C10G7/00
Abstract:
In methods for the Crude Distillation Unit, a desalted crude oil and water mixture is processed through a heating exchangers, cooling exchangers, and vapor-liquid phases separating vessels, fired furnace, superheated vapor steam, the liquid stream having a wide distillation boiling range and partially vaporized crude oil streams. These streams are processed in an atmospheric distillation column to generate the distillate products and long residue stream. The long residue generated from the ADC striping section is processed with steam in the separate vessel with plural trays or the new separation section with plural trays added to the existing ADC design. The methods result in simultaneous reduction in thermal energy, reduction in vacuum system load, opportunity to increase the crude throughput for a given diameter of ADC and eliminating need for a fired furnace for superheating the vapor stream to be used at bottom section of ADC.
