Standard Test Method for Determination of Light Hydrocarbons and Cut Point Intervals in Live Crude Oils and Condensates by Gas Chromatography

Importancia y uso:

5.1 This test method determines methane (nC₁) to hexane (nC₆), cut point carbon fraction intervals to nC₂₄ and recovery (nC₂₄+) of live crude oils and condensates without depressurizing, thereby avoiding the loss of highly volatile components and maintaining sample integrity. This test method provides a highly resolved light end profile which can aid in determining and improving appropriate safety measures and product custody transport procedures. Decisions in regards to marketing, scheduling, and processing of crude oils may rely on light end compositional results.

5.2 Equation of state calculations can be applied to variables provided by this method to allow for additional sample characterization.
