1. Figure below is a simplified block diagram of the crude distillation unit and the main units to process the distillation products. By considering this figure, answer the following questions: I. State the kind of pre-treatment that the crude oil receives, prior to entering the distillation column? II. List the main impurities found in crude oil? III. Identify the processing from 1 to 8 ?

Step 1
The pre-treatment that crude oil receives prior to entering the distillation column is **desalting**. This process removes salts and water from the crude oil. II. The main impurities found in crude oil are: - **Water** - **Salts** - **Sulfur compounds** - Show more…

The graph in Figure P11.4 describes the volume of distillate collected during the fractional distillation of a liquid. Answer the following questions about the process: (a) Is the sample a pure liquid or a mixture? (b) If it is a mixture: (i) how many components are in the mixture? (ii) What are the relative ratios of the volumes in the mixture? (iii) What are their approximate boiling points?
Crude Oil Place the following molecules, all of which are products of the distillation of crude oil, in order in which they would appear in the distillate during simple distillation: $\mathbf{C}_{6} \mathrm{H}_{14}, \mathrm{C}_{18} \mathrm{H}_{38}, \mathrm{C}_{12} \mathrm{H}_{26}, \mathrm{C}_{9} \mathrm{H}_{20}$
Use an Internet search engine (such as http://www.google .com) to locate information on fractional distillation of petroleum. List the names and boiling point ranges of six or more distillation fractions usually obtained from most crude petroleum.
