Questions and Answers

What is the main challenge in predicting hydrate formation conditions for mixtures containing non-formers?

  • Non-formers tend to have low gas specific gravity, making hydrate formation less likely.
  • Non-formers tend to be light hydrocarbons, which can form hydrates more easily.
  • Non-formers tend to be heavy hydrocarbons, which may liquefy at hydrate formation conditions. (correct)
  • Non-formers tend to have high gas specific gravity, making hydrate formation more likely.

    • What effect can non-formers have on hydrate formation pressure in a mixture?

  • The hydrate formation pressure will always be lower than for the pure former.
  • The hydrate formation pressure may not follow any simple rules of thumb. (correct)
  • The hydrate formation pressure will be the same as for the pure former.
  • The hydrate formation pressure will always be higher than for the pure former.

    • Which of the following is NOT mentioned as a way to avoid hydrate formation in natural gas streams?

  • Add hydrate inhibitors.
  • Operate outside the hydrate formation region.
  • Increase the gas specific gravity. (correct)
  • Dehydrate the gas.
