Abstract:
ASTM D664 and ASTM D3227 are among the most widely applied titration methods in petrochemical and refining laboratories, providing critical information for product quality, process control, corrosion prevention, and asset protection. This course reviews the principles and practical implementation of potentiometric titration for Acid Number (ASTM D664) and Mercaptan Sulfur (ASTM D3227) determinations. Attendees will learn best practices for sample preparation, electrode selection, method optimization, and troubleshooting common challenges. The session highlights how automated titration improves accuracy, repeatability, and laboratory efficiency while ensuring reliable results across diverse petrochemical samples.
