Feb 08, 2022 The crude oil fractions with higher boiling points: have more carbon atoms. have higher molecular weights. ... The reason that fractional distillation gives better separation between the liquids is because the glass beads in the fractionating column provide “theoretical plates” on which the refluxing liquid can condense, ...

May 01, 2009 Molecular distillation of bio-oil at 70 C, 100 C and 130 C were investigated in this study to explore the effects of the evaporation temperature on the separation of compounds. The bio-oil was divided into three fractions: light, middle and heavy fractions. All samples were kept under − 4 C in the refrigerator.

Oct 15, 2018 Distillation examples . The refining of oil . . To separate the various hydrocarbons and petroleum derivatives , a fractional distillation method is carried out that allows each of these derivative compounds to be stored in different layers or compartments, from the cooking of the crude oil. The gases rise and dense substances such as asphalt and paraffin fall separately.

Oct 31, 2019 Advantages and applications: Maximum yield is obtained. Minimal loss of oxygenated components maximum yield as compared to water distillation. Disadvantages: More time consuming due to due to the low pressure of rising steam. Water on the substance to be distilled causes it to vaporize in delayed time [10].
