Q1:

A typical yield of kerosene in straight run distillation of crude oil may be about __________ percent.

A 4

B 10

C 18

D 26

ANS:B - 10

A typical yield of kerosene in straight run distillation of crude oil is about 18 percent. Here’s an explanation:

  1. Straight Run Distillation: In crude oil refining, straight run distillation is the initial process where crude oil is heated and separated into fractions based on their boiling points.
  2. Fractional Yield: Kerosene is typically obtained as a middle distillate fraction during this process. The yield of kerosene depends on the specific characteristics of the crude oil being processed and the refining conditions.
  3. Typical Yield: On average, the yield of kerosene from straight run distillation is approximately 18 percent of the total crude oil processed. This yield can vary based on factors such as crude oil composition, refining technology, and desired product specifications.
Therefore, a typical yield of kerosene in straight run distillation is around 18 percent, indicating the proportion of crude oil that is separated and collected as kerosene during the initial refining stages.
