AbolishedStandard test method for distillation of heavy hydrocarbon mixtures(Vacuum potstill method)
重烃类混合物蒸馏试验方法(真空釜式蒸馏法)
Application Summary AI generated
This standard specifies a vacuum potstill method for determining the boiling range distribution of heavy hydrocarbon mixtures that decompose at atmospheric pressure. It is applied in the petroleum and petrochemical industries for testing crude oil residues, heavy fuel oils, and other high-boiling-point fractions. The method is used in quality control and product specification verification to ensure accurate distillation data without thermal cracking.
