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

Question 6:

A partial condenser is an overhead product water-cooled condenser:

A - Through which the flow of cooling water is regulated B - Receives the condensed overhead product before it is pumped back into the tower or to storage C - Is used to condense the entire vapour product flow coming from the top of the fractionator D - Containing finned tubes to increase the surface of the exchanger Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 7:

When the overhead product contains light ends having a high vapour pressure, the gases will not be condensed but will need to be pressure-controlled from the:

A - Reflux accumulator B - Bottom heat exchanger C - Overhead condenser D - Reboiler Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 8:

The component used with a fractionation tower that provides a volume of overhead condensed liquid to the tower is called the:

A - Reboiler B - Bottom heat exchanger C - Reflux accumulator D - Overhead condenser Correct Answer(s): C Marked as: Incorrect _______________________________________________

Question 9:

The component used with a fractionation tower that provides reflux to the tower is called the:

A - Bottom heat exchanger B - Reboiler C - Reflux pump D - Overhead condenser Correctness Rule: Single Correct Answer Required Answer(s) Given: C Correct Answer(s): C Marked as: Correct _______________________________________________

Question 10:

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

A - Atmospheric pressure B - Convection C - Compressors D - Fans Correctness Rule: Single Correct Answer Required Answer(s) Given: D Correct Answer(s): D

Question 1:

A total condenser is:

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

Question 2:

With the flooded condenser, the tower pressure is controlled by the rate the product flows to the reflux accumulator from storage.

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

Question 3:

When the overhead product contains light ends having a high vapour pressure, the gases will not be condensed but will need to be pressure-controlled from the:
