RPCH024 - Oil Desalting System

Programme Overview

Oil desalting systems provide protection to capital intensive processing equipment by removing the salt component from crude oil.  There are many significant variables to control in the crude oil production process.  This course provides participants with knowledge necessary to understand that the desalting operation is one that must constantly be adjusted to maintain optimum performance.

The course will move from the fundamentals of the desalting process, through to the various design options and major process variables.  Discussion will also include topics on electrical desalting and the types of desalting systems.

As the course progresses, discussion will focus on design considerations, components, operation, performance, and troubleshooting tactics used in desalting operations.

Who should attend

Engineers, senior operation personnel and technical supervisors interested or involved in the operation, optimization and monitoring of crude oil atmospheric distillation and residue vacuum distillation units.

By the end of this training course, participants will:

  • grasp fundamental process control and the impact of each controller on the process and on the characteristics of the cuts produced,
  • analyse desalter operation and corrosion monitoring,
  • detect potential deficiencies by troubleshooting.
