10. Answer the questions

    1. What fuels does crude oil convert into during refining?

    2. What process units are commonly used in oil refinery?

    3. What causes the liquid to “fractionate”?

    4. Why is oil desalting used?

    5. What is the vacuum fractionation intended for?

11. Read and translate

  1. Water and chemical surfactants are added to the crude, heated so that salts and other impurities dissolve into the water, and then held in a tank where they settle out.

  2. The desalted crude is continuously drawn from the top of the settling tanks and sent to the crude distillation tower.

  3. The lightest fractions, including gasoline and liquid petroleum gas, vaporize and rise to the top of the tower, where they condense back to liquids.

  4. The amount of heat entering the column from the reboiler and with the feed must equal the amount of heat removed by the overhead condenser.

  5. The preheated high-boiling petroleum feedstock is combined with recycle slurry oil from the bottom of the distillation column and injected into the catalyst riser where it is vaporized and cracked into smaller molecules of vapor.

  6. The main fractionator offgas is sent to the gas recovery unit where it is separated into butanes and butylenes, propane and propylene, and lower molecular weight gases.

  7. The mixture is heated by heat exchange with reactor effluent and by a furnace and enters a reactor loaded with catalyst.

  8. After passing the heat exchanger, the reaction products are cooled in air coolers and routed to a product separator, where the hydrogen is the main gaseous product.

  9. When heavy oil fractions are passed in gas phase through a bed catalyst at a suitable velocity, the catalyst and the gas form a system that behaves like liquid.

  10. The liquid feed is pumped up to the reaction pressure and is joined by a stream of hydrogen-rich recycle gas.
