Simulated Distillation (SimDis) based on gas chromatography is one of the most common used analysis techniques in the petrochemical industry. A SimDis report gives valuable information on the boiling point distribution of crude oils and petroleum feeds. This information is essential for refinery engineers to determine the most efficient way to operate and control the distillation process. Therefore a good, robust and reliable SimDis analyzer is an essential tool for the optimal (and economical!) operation of a refinery unit.
Many different methods have been standardized for oil samples with different final boiling points. These methods sometimes require different columns, different analytical parameters and reference samples.
