CE Instruments - Simdist

Besides the boiling point distribution report , a quality control report is available as well. This report shows the conformity with reference samples, and is therefore very important for the overall reliability of the method. See table 3: 'LIM' shows the allowed deviation, while 'DIF' is the actual difference.

Simdist reporter provides several correlations such as :

• ASTM D86 and D1160, giving you the correlation for respectively atmospheric and vacuum distillation of your samples.
• DIN 51.581 (NOACK) is reporting the evaporative loss in mass% of lubricants at 250ºC.
• ASTM D 6417 (MOV) is reporting the evaporation loss in mass% of lubricants at 371ºC.
• ASTM D54 Reid vapor pressure (RVP) is reported for samples analysed according.
• Correlation to ASTM D56, reports Flashpoints of the varous methods used.
• Cut point tables can be user added to the Simdist report when required.

Simulated distillation (Simdist) is a GC method, used to characterize petroleum products, fractions, lube oil and crude oil. Simdist determines the boiling range distribution in a quick, automated and reliable way. This method replaces the laborative and dangerous D86/1106 methods. True boiling point (TBP) data is vital information for improving refinery profit margins.
Samples are analysed on a non polar column, separating hydrocarbons in order of their boiling points. These are correlated with the retention times from a range of n-alkanes eluting under exact the same conditions and in the range of the sample. A blank analysis is subtracted from the sample chromatogram in order to correct for column bleeding. It is of great interest that the GC instrument has a very good run to run reproducibility.
Results are reported as a correlation between the boiling points and the percentages of the sample eluted from the column. The results are confirmed by running a well known standard sample as external standard. The Simdist data correlates with ASTM D86 or D1160.
The determination of boiling point distribution of petroleum products and crude oils by conventional GC is a rapid and reliable tool, which is widely used to replace conventional distillation methods. This proven technology is supported by several standard methods..
