In general, condensate stabilization accomplishes several functions, including:

A - Sweetening the product by adding hydrogen sulphide and carbon dioxide B - Raising the condensate vapour pressure while lowering evaporation losses through storage or shipment C - Lowering the condensate vapour pressure and evaporation losses while the product is in storage or shipment D - Ensuring a consistently high pentane content in the lean absorption oil Correctness Rule: Single Correct Answer Required Answer(s) Given: C Correct Answer(s): C Marked as: Correct _______________________________________________

Question 3:

Stabilization by fractionation is a single tower process because:

A - Two specification products are required. B - Only one specification product is required. C - Precise production of liquid of suitable vapour pressure is not necessary in the process. D - The finished product from the bottom is composed mainly of butane. Correctness Rule: Single Correct Answer Required Answer(s) Given: B Correct Answer(s): B Marked as: Correct _______________________________________________

Question 4:

Stabilization by fractionation makes a cut between the heaviest gas and:

A - Butane B - Propane C - Pentane D - Ethane Correct Answer(s): C Marked as: Incorrect _______________________________________________

Question 5:

The removal of the methane, ethane, and propane from the stream and the reduction of butane content:

A - Increases the production of sales gas B - Raises the condensate vapour pressure and lowers evaporation losses C - Lowers the condensate vapour pressure but increases evaporation losses D - Decreases the production of sales gas Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 6:

Flash vaporization releases large quantities of vapour by:

A - Increasing the temperature in stages B - Increasing the pressure in stages C - Reducing the pressure in stages D - Reducing the temperature in stages Correctness Rule: Single Correct Answer Required Answer(s) Given: C Correct Answer(s): C Marked as: Correct _______________________________________________

Question 7:

In natural gasoline, the maximum allowable butane content, without a penalty, is usually:

A - 1.5% by volume B - 1.75% by volume C - 0.5% by volume D - 15% by volume Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 8:

Equilibrium vaporization occurs when the vapour and liquid phases are in equilibrium at the:

A - Inlet of the fractionation tower B - Highest point on the Reid Vapour Pressure scale C - Initial temperature and pressure of separation D - Final temperature and pressure of separation Correctness Rule: Single Correct Answer Required Answer(s) Given: D Correct Answer(s): D Marked as: Correct _______________________________________________

Question 9:

To ensure that the vapour pressure can be adjusted to the product customers desired level, gas plant finished gasoline contains small amounts of:

A - Methane B - Propane C - Octane D - Butane Correct Answer(s): D Marked as: Incorrect _______________________________________________

Question 10:

Stabilization by fractionation makes a cut between the lightest liquid component and:
