Characteristics Of Natural Gas Practice Test

What percentage of propane and heavier hydrocarbons does natural gas contain?

1% 2% 3% 4%

Correct Answer:

Explanation:

The amount of propane and heavier hydrocarbons in natural gas is typically very small, usually about 1% by volume. These heavier components (the C3+ fraction) can condense into liquids if present in larger amounts, which creates processing and pipeline handling challenges. Because gas must meet pipeline specifications and avoid liquid formation, it’s common to find and aim to keep this fraction around a modest, low level like 1%. Higher percentages would require more extensive processing to remove the liquids, which is why the standard value emphasized in many guidelines is about 1%.
