Oil Treating and Desalting Systems

Desalting provides protection capital intensive refinery equipment by removing the salt component from crude oil.  There are many significant variables to control in the crude oil operation therefore the desalting operation 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.
