Crude-oil pretreatment additives

Crude-oil pretreatment combines separation and contaminant-removal treatments before downstream refining. The application review considers crude blend, desalter behavior and contaminants of concern so that treatment functions can be assessed within the same operating context.

Application and function

Demulsifiers address oil–water separation, while calcium and iron removal additives address selected metal-related problems. The appropriate combination follows the observed operating issue and supporting analyses.

Review the current chemical program alongside desalter operation. Changes in crude blending, wash-water quality or interface behavior may affect which treatment needs attention.

Information for selection

  • Water, salt, solids and relevant metals in incoming crude
  • Oil–water separation, interface stability and effluent quality
  • Mixing, residence time, injection facilities and downstream constraints

Evaluation and technical review

Set separate criteria for separation and contaminant removal. Laboratory screening with representative material can inform selection, followed by a monitored plant evaluation.

Review treated-crude quality and separated water together, recording changes in feed and operating conditions.

Discuss product selection

Share the application, operating conditions and requirements that matter to your evaluation. Product-specific properties, use guidance and handling information are provided in the relevant product data sheet and safety data sheet.
