1. Lubricants differ in properties depending upon the hydrocarbons they contain. 2. By processes similar to those we considered earlier the residual oil vapour is fractionated in the column into cuts. 3. Any mineral a metal can be obtained from is called an ore. 4. We find rock beneath the soil the surface of the earth is covered with. 5. The process oxygen takes part in is known as oxidation. 6. Some polymers the scientists discovered possess remarkable properties.

 

8. , (What, Where, When, How, etc.):

1. The liquid part of the petroleum passing downwards through the bubble plates forms residual oil. 2. Superheated steam is supplied at the bottom of the column. 3. The processes of evaporation and condensation repeated on plate after plate make for the better fractionation of the petroleum. 4. As they pass through heat exchangers, the cuts give up their heat to petroleum about to enter the pipe still. 5. The cuts are then purified by means of sulphuric acid and alkali. 6. Cuts, after purification, yield various lubricants. 7. The atmospheric unit serves to distill petroleum.
