The graph below is an example of a typical positive displacement compressor. Which of the numbered points would best be described as when the cylinder is full of gas at suction pressure?
If an unusual condition appears, compressor control systems have instruments that will shut down the compressor safely. Which of the shutdown classes below is best described as having no time limits, and armed when the process is in operating limits, and
In a SIS, the collection of redundant components must be connected in a specific way. Which of the terms below is used to describe this arrangement?
Responses from feedforward controls have different times. Which of the answers below is not a timed response?
There are several common problems that can arise during a distillation columns operation. Which of the problems below can be described as an accumulation of liquid that can block vapour from rising?
Because steam demands can vary, there are several control methods that work in concert to ensure efficient boiler operation. Which of those strategies would be to control the water level in the steam drum?

Which of the terms below is best describes when the other control loop is in manual, the disruption in the PV with a change in Co?
SAMA has various symbols for the elements or functions of a boiler. Which of the answers below correctly identifies "A"?
A system of control is needed in a reciprocating compressor to have consistent pressure. Which of the control systems below is best described as one that changes the compressors capacity?
There a some conventional distillation column control strategies. Which of the strategies below is best described as a direct setting of one of the output flows?
There are many different parts and processes to a distillation column. Which of the processes below can be best described as the residual liquid exiting the tray at each stage?
There are many different parts and processes to a distillation column. Which of the design feature below can be best described as the section that concentrates the heavier component in the liquid phase.
Surge is the worst conditions that a centrifugal compressor can have, so some control strategies have been developed to mitigate this. Which of the strategies below can be described as a control that functions despite the surge controller not operating?
Compressors are split into general categories by how they produce downstream pressure. Which of the answers below would a centrifugal compressor be classified as?
