Calcium Removal from Crude Oil via Desalter Acidification
Carol El-Halabi, M.Sc. - Technical Consultant, Veolia Water Technologies & Solutions
This presentation discusses a unique approach to desalter acidification in which a proprietary acid blend is applied to a two-stage desalter system to extract organometallic calcium from incoming raw crudes. Veolia supplemented their proprietary acid program with heavy crude oil emulsion breaker technology to optimize crude dehydration and demulsification. The results achieved the KPI target of calcium in desalted crude and mitigated calcium deposition in downstream effluent equipment. The presentation concludes with future improvements for enhanced performance and processing opportunities.
