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.
