ActiveStandard test method for distillation of heavy hydrocarbon mixtures—Vacuum potstill method
重烃类混合物蒸馏试验 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 industry for quality control and process evaluation of products such as crude oil residues, heavy fuel oils, and lubricating oil base stocks. The method is particularly relevant for testing samples with initial boiling points above 150°C under reduced pressure to prevent thermal cracking.
