The present research study investigated the effect of time duration on crude fractions corrosivity in high temperature experiments performed in a flow through apparatus with continuous replenishment. The experiments duration varied from 1 to 7 days and assessed the corrosivity as function of time for three different vacuum gas oils (VGO). Along with the metal loss evaluations, naphthenic (NAP) acids and sulfur species concentrations were monitored by potentiometric titrations and X-Ray Fluorescence spectrometry (XRF), respectively. Corrosion damage of the metal surfaces and the scales formed on them were analyzed by Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS). The study provided valuable information on NAP acids and sulfur species corrosivity and their chemical evolution during long time experiments by integrating metal losses with feed and product analyses.

Key words: naphthenic acid corrosion, sulfur corrosion, crude fractions, time effect, high temperature
