Crude Distillation Operations
Overview:
Operators must properly monitor and control the distillation process in the crude unit so that the products leaving the unit meet process specifications. This course provides an overview of the operation of a crude distillation unit. The steps that crude oil goes through in the crude unit, process variables, and conditions that affect unit operation will also be examined. This course will also consider problems that might arise in the crude distillation unit and how to correct them.
Duration:
60 hrs.

    • Operation of a typical desalter
    • Desalter operation
  • Topic III: Crude Distillation
    • Flash drum and a pre-fractionator
    • Atmospheric distillation tower
    • Vacuum distillation tower
  • Topic IV: Process Variables
    • Charge heater
