During frictional distillation, which of these components of crude oil does not condense on any of the trays in the fractioning column?

Options

A. Gasolin
B. Paraffin wax
C. Petroleum gas
D. Naphtha

Answer

To solve the question regarding which component of crude oil does not condense on any of the trays in the fractionating column during fractional distillation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Fractional Distillation**: Fractional distillation is a process used to separate a mixture into its component parts based on differences in boiling points. In the case of crude oil, it is separated into various fractions such as gasoline, kerosene, diesel, and others.

2. **Identify the Components**: The components mentioned in the question are:
- Gasoline
- Paraffin wax
- Petroleum gas

3. **Analyze Each Component**:
- **Gasoline**: This is a liquid at room temperature and has a relatively low boiling point. It condenses on the trays of the fractionating column.
- **Paraffin Wax**: This is a solid at room temperature and has a higher boiling point. It typically condenses at higher temperatures and may not condense until the lower trays.
- **Petroleum Gas**: This consists mainly of gases like propane and butane, which have very low boiling points. They remain in the gaseous state and do not condense on the trays of the fractionating column.

4. **Conclusion**: Since petroleum gas remains in the gaseous state and does not condense on any of the trays in the fractionating column, it is the correct answer to the question.

### Final Answer:
The component of crude oil that does not condense on any of the trays in the fractionating column is **Petroleum Gas**.
