Welcome to this assessment

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?


HERVE BARON



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 and are shown on the Utility consumptions list.

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

As per the piping code for Oil & Gas plants (ASME/ANSI B31.3), the wall thickness of a line

Is proportional to the line diameter

Is proportional to the square of the line diameter

Is proportionally to the line pressure

Is proportionally to the square of the line pressure

Depends on the manufacturing process of the line pipe
