In the regeneration section of a teg plant the solution is heated in a coil immersed in the glycol surge tank and then discharged into the:

A - Still column B - Flash drum C - Absorber D - Pump suction Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 10:

An operator wishes to increase the dew point depression from 30°C to 36°C on a plant's TEG dehydration unit. The action required to reach this is:

A - Increase reboiler temperature B - Decrease gas flow rate C - Increase circulation of glycol D - Reduce operating pressure in absorber Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct Question 1:

In the glycol regeneration section of a teg plant, with the stripper:

A - Glycol-rich vapour from the reboiler rises in intimate contact with descending water-rich liquid from the absorber B - Water-rich vapour from the reboiler descends in intimate contact with rising glycol-rich liquid from the absorber C - Water-rich vapour from the reboiler rises in intimate contact with descending glycol-rich liquid from the absorber D - Water-rich vapour from the absorber rises in intimate contact with descending glycol-rich liquid from the reboiler Correctness Rule: Single Correct Answer Required Answer(s) Given: C Correct Answer(s): C Marked as: Correct _______________________________________________

Question 2:

In the regeneration section of the TEG plant, the reboiler temperature requirements are:

A - Higher than in a DEG plant B - The same as in a DEG plant C - Lower than in a DEG plant D - Dependent on the design limits of the reflux equipment Correctness Rule: Single Correct Answer Required Answer(s) Given: A Correct Answer(s): A Marked as: Correct _______________________________________________

Question 3:

In the regeneration section of a TEG dehydration plant the rising water-rich vapour is in intimate contact with the descending glycol in the:

A - Surge tank B - Stripper column C - Contactor D - Separator Correctness Rule: Single Correct Answer Required Answer(s) Given: B Correct Answer(s): B Marked as: Correct _______________________________________________

Question 4:

In the regeneration section of a TEG plant the solution is heated in a coil immersed in the glycol surge tank and then discharged into the:

A - Absorber B - Flash drum C - Pump suction D - Still column Correctness Rule: Single Correct Answer Required Answer(s) Given: D Correct Answer(s): D Marked as: Correct _______________________________________________

Question 5:

Preventive dehydration controls the moisture content in gas by injecting certain inhibitors or chemicals. One drawback of ammonia inhibitors is that they:
