Wrong

The correct answer is: The oil pressure in the system falls

Before starting the circulation of lube oil, the oil level in the oil reservoir must be:

  a) Higher than normal
  b) Normal
  c) Lower than normal

Wrong

The correct answer is: Higher than normal

During the pre-startup operation, the compressor should be started before the lube and the seal oil circulation has commenced.

  a) True
  b) False

Wrong

The correct answer is: False

If the seal oil pressure is lower than the gas pressure, what would happen?

  a) The seal oil temperature will increase too high.
  b) The gas temperature will increase too high.
  c) The gas will leak through the seal.
  d) All the above

Wrong

The correct answer is: The gas will leak through the seal.

Maintaining the oil level in the seal oil head tank at the design value is important to:

  a) Ensure pressure difference between the seal oil and the gas
  b) Avoid damage to the head tank
  c) Ensure that the seal oil pressure is the same as that of the lube oil pressure

During the oil circulation, the lube and the seal oil filters should be inspected to ensure that:

  a) No air is trapped inside the filters
  b) The differential pressure across the filter is normal
  c) Both a and b

The purging of the compressor casing is done to:

  a) Remove any oxygen that may be present in the casing
  b) Remove inert material from the casing
  c) Introduce oxygen into the casing
  d) Introduce inert gas into the casing

Wrong

The correct answer is: Remove any oxygen that may be present in the casing

When the oil level in the seal oil head tank fluctuates rapidly, it may indicate gas leak through the seal.

  a) True
  b) False

Wrong

The correct answer is: True

The gas must be introduced slowly to the compressor because:

  a) There may be an excessive increase in the temperature of the compressor
  b) There may be fluctuations of the oil level in the seal oil head tank
  c) There may be some condensate trapped in the casing

Wrong

The correct answer is: There may be fluctuations of the oil level in the seal oil head tank

The air present in the surface and the gland steam condensers is usually removed by:

  a) An ejector
  b) A pump
  c) A turbine
  d) A compressor

Wrong

The correct answer is: An ejector
