During the process, the parts, or fractions of crude oil are divided out successively by their increasing molecular weight. For instance, gasoline has a low molecular weight and vaporizes at a fairly low temperature. This means that at the appropriate temperature, while all of the rest of the oil is still in liquid form, gasoline may be separated out. The remaining oil goes... <figure class="wp-block-image aligncenter size-full"><img src="https://www.primacyebooks.com/wp-content/uploads/2024/09/Fractional-Distillation.png" alt="Fractional Distillation" class="wp-image-20890"/></figure> <div class="sign-up-notice-after-excerpt-two" style="background-color:powderblue;"> You are viewing an excerpt of this lesson.
