In a thermal siphon reboiler, the bottom product flows to the bottom of the reboiler by using:

A - Gravity B - Centrifugal force C - Convection D - Induction Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 5:

The component labeled "A" on the illustration of the horizontal fired heater shown is called the:

A - Stack B - Burner C - Breeching D - Firebox Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 6:

The reflux accumulator, or reflux drum, is part of the condensing equipment. The accumulator pressure corresponds to the bubble point pressure of the liquid at its temperature in the vessel.

A - True B - False Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 7:

If you were operating a tower where the bottom temperature is controlled by constant heat input to the reboiler, how would you control the tower temperature?

A - By adjusting the pressure difference between the rectifying and stripping sections B - By reducing the power consumption of the reflux pumps C - By changing the reflux flow D - By controlling the pressure differential between the top and bottom Correctness Rule: Single Correct Answer Required Answer(s) Given: C Correct Answer(s): C Marked as: Correct _______________________________________________

Question 8:

If the fractionator bottom temperature is too hot:

A - Some of the bottom product will be driven overhead B - The reflux accumulator must be shut down C - Some of the overhead product will condense out in the bottom product D - The tower temperature must be adjusted by changing the reflux flow Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 9:

Which type of heating equipment used in a fractionation system uses only convection to produce circulation?

Question 2:

A total condenser is:

A - Used to condense the entire vapour product coming from the top of the fractionator B - A heat exchanger containing finned tubes to increase the surface of the exchanger C - The part of the condensing equipment that receives the condensed overhead product before it is pumped back into the tower or to storage D - A partial condenser through which the flow of cooling water is regulated Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 3:

In a fin fan cooler, air is forced across the tubes by:
