Fractional distillation is used to separate a mixture of two or more miscible liquids with a difference in boiling points of less than 25 K.For example, the distillation process is utilised for separation of various gases from air, various divisions of petroleum products etc. The oil is extracted by heating the plant material and distilling the vapour. Some facilities such as storage and effluent control may even have an index greater than 1.0. The United States is the world's leading consumer of petroleum. Fractional distillation. The only difference between this and a simple distillation set-up is the inclusion of a fractionating column (see close-up below) between the round bottom flask and the Y-adaptor. Effective separation can be achieved by using a long vertical column (fractionating column) attached to the distillation vessel and filled with glass beads. It can be performed in a continuous mode involving continuous sample feed to the column or a batch mode where a discrete batch of sample is placed in the boiling flask. CHAPTER I PROPERTIES OF EXPLOSIVES Definition An explosive is a material, cither a pure single substance or a mixture of substances, which is capable of producing an ex- plosion b Paraffin wax, diesel, lubricating oil, gasoline, kerosene and naphtha are the substances that crude oil contains. Storage is a serious problem with large plants. In this experiment, students use a crude oil substitute to model the fractional distillation of crude oil. After collecting four fractions at different temperatures, students test each one for viscosity, colour, smell and flammablility. Teachers will need to assess whether this activity can be done as a class experiment or as a demonstration. The components in a sample mixture are vaporised by the application of heat and then immediately cooled by the action of cold water in a condenser.
