Article: Physical vacuum distillation and high temperature simulated distillation of residual oils from different origin Journal: International Journal of Oil, Gas and Coal Technology (IJOGCT) 2018 Vol.17 No.2 pp.208 - 221 Abstract: High temperature simulated distillation (HTSD) of residual oils is not only faster but also more precise than the physical vacuum distillation (ASTM D-5236). However, the HTSD ASTM D-7169 method could report wrong results if it is not performed properly. A verification of the correctness of the HTSD analysis could be accomplished by comparison of the HTSD curve with the one of the physical vacuum distillation methods (ASTM D-1160 or ASTM D-5236).

The conversion of HTSD in ASTM D-5236 developed in this work is able to predict the distillation curve of the ASTM D-5236 vacuum distillation with almost the same precision as its repeatability of the method.

Abstract: High temperature simulated distillation (HTSD) of residual oils is not only faster but also more precise than the physical vacuum distillation (ASTM D-5236). However, the HTSD ASTM D-7169 method could report wrong results if it is not performed properly. A verification of the correctness of the HTSD analysis could be accomplished by comparison of the HTSD curve with the one of the physical vacuum distillation methods (ASTM D-1160 or ASTM D-5236). The calibration blend, design of the liner, the GC inlet temperature, and the concentration of heavy oil sample in CS₂ were found to have a considerable impact on the correctness of the reported results. The conversion of HTSD in ASTM D-5236 developed in this work is able to predict the distillation curve of the ASTM D-5236 vacuum distillation with almost the same precision as its repeatability of the method.
