The Development of a True Boiling Point Distillation Apparatus

摘要

A new true boiling point distillation apparatus was designed, fabricated, and tested as part of a larger research effort on characterization studies of condensate fluids. Mixtures from heptanes, C_6, to dodecanes, C_(12), were separated under atmospheric conditions and from tridecanes, C_(13), to nonadecanes, C_(19), under vacuum conditions. Benchmarking of the results from true boiling point analyses was performed by high-precision gas chromatography. Such data are not only scarce but those available indicate differences ranging from 20 to 30% mainly due to carryover of volumes outside the boiling range. This work has shown a difference of less than 10%, which indicates that this new true boiling point equipment is capable of producing results suitable for conducting reservoir fluids characterization studies.
