Crude Pretreatment — Metal Removal

Calcium and iron removal additives support crude-oil pretreatment in the desalter. Selection depends on the metals present, crude blend and separation conditions, within the existing desalting and effluent-handling program.

Application and function

Metal-containing material in crude oil can contribute to desalter-interface problems and carry contaminants into downstream processing. Treatment options assist the transfer of targeted metals and solids into the separated water phase.

Formulation chemistry and suitability should be considered against the contaminant profile. Review metal removal together with oil–water separation, wash-water conditions and the existing demulsifier program.

Information for selection

  • Calcium and iron analyses for incoming crude and treated oil
  • Crude-blend changes, interface behavior and solids loading
  • Wash-water quality, effluent constraints and chemical compatibility

Evaluation and technical review

Compare candidate treatments using representative crude and wash water before a monitored plant evaluation. Review metal reduction, separation quality and the condition of the aqueous phase together.

Record operating changes during the evaluation so they can be distinguished from treatment effects.
