Desalting and Vacuum Distillation Principles in Petroleum Refining

Desalting is a critical process within the workflow, the application of which is contingent upon specific criteria.
Determination Criteria: A refinery must determine whether to proceed with desalting based on the composition of the crude material.
Salt Deposit Thresholds: The decision to undergo desalting is directly linked to the density of salt found in the deposits. Specifically, if the material exhibits "higher salt deposits," it is mandatory to perform the desalting process.

Operational Methodology: The process referred to as "vacuum installation" functions by altering physical environmental variables rather than increasing thermal energy.
Temperature Control: Unlike standard distillation, the vacuum installation does not involve an increase in temperature.
Pressure Reduction: The core mechanism of this process is to "decrease the pressure."
Rationale for "Value Insulation": The underlying "sense" or goal of employing these methods is the optimization of output.
Product Yield Increase: By decreasing the pressure, the refinery is able to extract and secure a higher quantity of petroleum products than would be possible under standard conditions. Specifically, the speaker notes that "you get more petroleum products out of it."
