METHOD FOR DETERMINING TRUE BOILING POINT FOR CRUDE OILS

摘要

This invention relates to a method for rapidly determining weightand volume percent true boiling point curves for crude oils and fractions thereof.The method involves at least a partial separation of the crude oil or fraction intoconstituent chemical components, obtaining mass spectra of the chemicalcomponents, correlating retention time windows with boiling points for standardhydrocarbon mixtures, and converting the total ion current obtained from themass spectra for selected components to weight and volume percent true boilingpoints by comparison with data obtained from a standard crude oil or fractionthereof.
