Crude Oil Analyzer Combines DHA and SIMDIS Techniques
The analyzer combines DHA and SIMDIS techniques to provide accurate crude oil analysis. High temperature simulated distillation (SIMDIS) is used to determine the boiling point range of crude oil. As the sample is normally diluted with a solvent such as CS2, there is a quenching effect that influences the accurate determination of the light end of a crude oil. The detailed hydrocarbon analysis (DHA) method uses a single capillary column technology equipped with a pre-fractionator conform IP 344 to characterize the front end in crude oil. Both applications use an Agilent 6890 Series gas chromatograph equipped with a dedicated column, inlet or pre-fractionator, a flame ionization detector and an automatic liquid sampler. A set of calibration and reference samples completes the applications. The analyzer features a high temperature SIMDIS application and a DHA front end application, and it complies with ASTM D 7169, IP 545 and prEN 15199-3.
