The Oil & Gas Engineering Quiz

Welcome to this presentation.

It will test you general knowledge as a Project Engineer.

Good luck!

Comments are most welcome ([email protected]),

which I will incorporate for the benefit of all.

The Heat & Material Balance (HMB) shows the flowrate, conditions and

composition of process and utility streams.

Right or Wrong?

Wrong, only the process streams. Utility streams, such as cooling water

flowrate etc., are defined later on, once equipment is sized.

Consider a process unit with an INPUT and OUTPUT.

The following is true:

� INPUT flow rate (kg/hr) = OUTPUT flow rate (kg/hr) – True (mass

balance)

� INPUT flow rate (kmol/hr) = OUTPUT flowrate (Kmol/hr) – False, if

chemical reaction has occured

� INPUT enthalphy (kJ/hr) = OUTPUT enthalpy (kJ/hr) – False, if heat or

mechanical work has been exchanged with outside

Which Engineering document do I need to estimate the cost of a

pressure vessel?

� The Process data sheet

� The Mechanical data sheet, as it indicates the equipment weight from

which I can estimate the cost (for pressure vessels, for instance, USD

4/kg for carbon steel and USD 12/kg for SS)
